08. YESWELDER TIG-250P AC DC 250 Amp TIG Welder

A good TIG welder is a powerful tool that can be used to weld metals together. I'll talk about the YesWeld 250P AC/DC TIG Welding Machine because it's an excellent example of what a top-of-the-line TIG welder should be.

The first thing that you'll notice when you look at the machine is its compact size, meaning that this machine is perfect for working on small projects like jewelry and art pieces.

I love the way this machine operates because there are two modes: AC and DC. There's also a built-in gas valve which means no more fumbling around trying to find the valve or struggling with how to turn it off.

Besides this, YESWELDER TIG-250P AC DC 250 Amp TIG Welder is a Software Controlled Square Wave AC/DC TIG inverter welder is one that is controlled with software. You can choose what level of control you want. It has a digital set of the press, start current, upslope, and down slope time.

It also includes post gas time and finishes the current level. There are 2T or 4T trigger functions that allow for the welder to be controlled efficiently from start to finish.

A very cool feature is, the device saves your last welding parameters when it's turned off so that you can just turn it back on to have the same settings as before. The device also has an auto-recovery feature that will automatically set the same parameters as your last weld.

This is a great feature to have because it can help you get better at welding without having to worry about setting your welder up every time.

Although, it has settings for both DC and AC welding, as well as being able to weld aluminum. The TIG feature is easy to use, with a 0.5Hz-200Hz pulse frequency setting.

The air channel has a unique airflow design that helps increase the heat dissipation of power elements, control circuits, and minimizes dust absorption. The heat dissipation of these parts prolongs the welder’s lifespan and increases its reliability.

The beautiful and weird thing about this product is, Automatic-off when the trigger is released (the flow stops). The punch pulse indicator in the display panel keeps the user informed on timing punch impulse activation and electric output current during the punching process for efficient arc starting with low distortion.

Since it comes with accessories such as an argon hose, gloves, feet coverings, eye protection gear, and more- everything you need for welding except the shielding gas itself.

This is also a great portable option; the welder runs on 220V of power and weighs less than 30kg when fully assembled. It has an automatic off feature when it is not in use so it doesn't keep draining electricity from your circuit even if you aren't using it at the time.

Although this product has many great features, it does have a few downsides. The machine is not powerful enough to weld steel or stainless steel without having to go back and forth with the pedal or switch back to AC mode.

I also found that the machine didn't come with any instructions on how to set it up so if you're not familiar with welding or electricity in general, there's a small chance you might have some trouble determining how to connect the appropriate wires.

09. Miller Electric Maxstar welder

Miller Electric Maxstar welder is one of the best all-around welders on my list. I have been using it personally since I got it and really love the performance. The machine is a little expensive, but it is worth every penny of your money. This welder comes with some great features. Here are just some of them:

When you purchase this welder, you will find it to be an asset when welding with aluminum. Having a duty cycle rate of 35% when using 100 amps and 30% when using 150 amps, it can handle any welding project you throw at it.

Its super easy to the voltage and power settings, this welder is perfect for professionals who work in different parts of the world because it comes with dual input voltages of 230 volts and 115 volts. It also has a built-in gas solenoid for TIG welding which eliminates the need for a TIG torch with a gas valve.

Moreover, this welder is very lightweight so you can take it just about anywhere without worrying about carrying straps or heavy machinery. One great thing about this machine is that it starts arcs easily and has no problems with the weld puddle.

It also helps with welding smaller or deeper objects because it has a powerful high-frequency start. Welds will penetrate deeper and freeze faster when using the Advanced Squarewave AC with automatic post-flow protection around the weld. Auto-post flow helps protect the weld from contamination.

The biggest problem that most of the Miller's MiniMax owners have is that when they buy this welder, they don’t realize it isn’t a heavy-duty machine. So if you are looking for a welding machine for commercial use then this really isn’t the one you should purchase. However, it is great for small projects or things like motorcycle repair in your garage or maybe even your race car.

Overall, the Miller Electric Maxstar is mostly considered a good welder by its users because it surprisingly does not smoke much which makes it easier to see what you are doing when working on different projects like pole barns where there may not be much lighting.

How Does TIG Welding Works?

TIG welding works by using an inert gaseous environment in order to protect the weld pool from the atmosphere. This type of weld is more precise and easier for a novice to learn, as opposed to other types of mechanical welds. The gas covers the molten metal while it is being pulled into the joint, which gives you time to work without worrying about oxidation or contamination. With TIG welding, there's no grinding or polishing after the weld has been completed. Most of the time, it can be done in one pass.

How to choose the best aluminum TIG welder for the money?

This article will provide readers with information on how to choose the best aluminum TIG welder for the money. The article will explore factors such as price, power source, duty cycle, and more. Readers should be able to make a decision on which welding machine they would like to purchase after reading this article.

As with any product, readers should first determine what features are the most important to them. That way they can then find the product which has these features.

Being a professional TIG welder is not easy and it requires a lot of skill and practice in order to be one. Therefore, choosing the right machine for an aspiring welder is vital. We want to buy machines that don't damage easily or have some components which will break down after heavy use, thus losing all their value. In addition, we also need machines that allow us to learn how they work without much trouble as well as produce quality welds while making sure our safety is taken into consideration at all times.

The same goes for aluminum TIG welding: if you want to get great results, you need a machine that will help you achieve these goals.

Some of the things to consider when choosing an aluminum TIG welder are:

  • The cost of the machine

This is one of the most important factors. For some people, money isn't too much of an issue but for others, it might be one of their main concerns. So before buying any product, make sure you have enough cash to buy this product and still have some leftover for other expenses such as materials and repairs, etc. Money can be saved if readers choose a used machine instead of spending hundreds or thousands on something brand new, so make sure you do your research before deciding which welding machine to purchase.

If possible try out machines in order to get a feel for them. In the end, it will be your decision on which machine you want to buy and if you are happy with it then don't let anyone else tell you otherwise.

  • The power source of the machine

Mobile aluminum TIG welders are more popular because they give users the ability to move around easier than something that is highly portable. But what about those who need something bigger in order to do their job? If this is the case, then you might want to consider purchasing large models instead. They are stationary but can offer much more flexibility when it comes to using different types of electrodes and materials such as metals and non-metals alike. 

Some machines have both qualities so you can take them not only to work but also for recreational purposes or traveling on long trips.

  • The duty cycle of the machine

Before purchasing an aluminum TIG welder, make sure it has a good duty cycle so it can last longer and save you money in the long run. Duty cycles give users information regarding how much welding each machine can do before it needs to be cooled down. Higher quality machines have higher standard duty cycles which allow us to weld more with them without damaging them during our work.

You will find that some machines only have one duty cycle while others might have anywhere from 5-20 different ones depending on their model. It all depends on what you are going to use your machine for and how frequently you will need to use it throughout the day.

  • The kind of electrode that it uses

This is also very important depending on what you are going to use your machine for. Many models still have the old TIG torch design which isn't as effective as newer style machines, so if this is a major concern then I would advise against buying these kinds of products. If you just want to do some DIY work at home or in your garage and don't really plan on using your machine frequently, then older models should suffice just fine. 

However, if you want to do something more with your aluminum welding machine such as heavy-duty construction projects around the house or at work, then I would recommend looking into one that has a new technology attached to it. You will find that these kinds of machines have an excellent warranty and can produce quality welds if used in the right way.

  • Its durability

This is another important aspect to keep in mind. Most aluminum welding machines are made out of strong materials such as oxygen-free copper alloys, titanium, etc. So if you plan on purchasing a new machine then make sure it is durable enough so you don't need to spend too much money fixing it over time or replacing parts that often wear out with use. 

Also, note that those who live in areas where there are rugged terrains should consider buying heavy-duty models instead of something lightweight due to the extra weight they carry around everywhere they go. These models also come with better motors which means a greater weld output and more options to do other tasks around the house.

  • The design of the machine

Some machines have a compact size which makes them easier to carry around in your truck, car, or even storage. This is excellent for those who need something lightweight that they can take on the go without struggling with it so much. Other machines on the other hand might be large and stationary but also come with some high-tech components built into their systems such as an inverter power source and a multi-voltage TIG torch system. They are often used by professionals who work in construction but could easily be used at home as well, however, they can be quite expensive depending on what you are looking for in a certain model.

  • Are All TIG Torches The Same?

Not necessarily, but this depends more than anything else on the quality of the machine in question as well as its design. You can find cheaper ones with between 5-10 amps while others might have up to 20 amps or more. Of course, these kinds of machines will be much heavier and not exactly portable, so keep this in mind when shopping around for a new product to purchase. 

  • Its Temperature Capacity

The temperature capacity refers to how hot it can get while welding aluminum without damaging or damaging the metal in question. You will want to check this out as well before making the final purchase so make sure you get a machine that can handle that kind of extremes without any problems and keep it cool enough so your hands don't burn whenever you use it for an extended period of time.

  • The capacity of Aluminum Welding

Pure aluminum has a low strength. It also measures less weight, making it easy for welding or casting. This means aluminum is only used in low-temperature applications unless mixed with other elements. To join it, one can either braze or weld it. Therefore it’s combined with conventional methods applied to other metals. On the other hand, particular methods may be required. The strength needed, appearance, and alloy will determine the choice of technique.

  • Versatility

There are two methods used in TIG welding; Alternating current and Direct current. The DC modes work on all metals apart from aluminum. On the other hand, the AC suits both magnesium and aluminum. This means you must choose a welder capable of Alternating current. The AC set at high frequency gives consistency heat on the electrode. The DC models result in excess heat and low oxide cleaning.

  • Required Input Voltage

Where you intend to weld aluminum plays a crucial role in finding the best TIG welder. A voltage input of 220V can ideally supply enough power for a welder of 115v AC. This works best when welding indoors. The majority of TIG welding machines function correctly on this voltage input. Therefore the welder can either function on a single or three-phase plan.

  • How Many Welding Amps And Voltage Does The Machine Have?

Always consider the output Amperage when choosing your ideal welding machine. A higher amperage means a wide range of materials to weld. When it comes to aluminum TIG welder, one amp translates to 0.001 mm of material thickness. The more the output amperage, the more and thicker the materials to weld. A TIG welder with a maximum of 200 amp works best for thin aluminum materials of 65mm.

After you know what kind of work you will be doing with your machine, the next thing to consider is its welding amps and voltage. Some machines come with a standard 80-100 amps but some high-end models might have up to 120 amp or even more depend on the model and how it was engineered. Of course price wise they are going to cost significantly more than those that only have 80 amp systems attached to them

  • Portability

How portable is the welder machine you intend to buy? A portable TIG welder is more comfortable to carry from one point to the other. It should also be lightweight for a more comfortable movement when using it. You can go the extra mile and consider those welder with two carrying handles for great convenience.

  • IGBT Technology

Advancement in technology has seen a rise in powerful and efficient TIG of such latest innovations is the IGBT technology that allows for additional power and safety. This gives the welder a unique ability to produce both thin and thick materials. In addition, the technology gives the machine reliable, lasting arc stability. The TIG welder can work for many hours without any mechanical complications.

Can any TIG welder weld aluminum? What rod do I use for aluminum TIG welding?

TIG welding is far the best technique for welding. However, there are different types of TIG welders. While it’s true any TIG welder can correctly work, there are several considerations likely to affect the quality of your final work. Some of such factors include the amperage and current. To weld aluminum, one can use the following rods;


This is far the most suitable rod for AI-5Si weld metal deposits. It can be used with Ar shield gases for aluminum castings.


This type of rod can be used with Ar shield gases as it contains AI-12Si deposits and 12% silicon. The rod also rarely cracks as it flows better.


The 5356 rod contains Al-5Mg deposits can also be used with shield gases.

How to TIG weld aluminum.

It takes both skills and practice to achieve high-quality welds. Below are four main steps used to tig weld aluminum.

Step 1: torch and hand positioning.

Hand placement is the first primary control in this game. Use the base of your hand and brace the welding torch firmly on your wrist all the way to your last finger. Now in a forward position, hold it against the table and keep it steady. Place the torch in a slight backward position while pulling the tungsten near to your work piece. Keeping the tungsten at a far distance from the work piece will cause much overheating. As a result, you are likely to lose puddle control.

Step 2: Movement coordination

Once you master torch control and hand placement, next is the flow and movement. Do it using gloves like typical welding. Firmly hold the torch with moderate pressure on the hands. Now in a smooth but motion, move your hands across the table. Move the whole hand, and not just fingers. This way, you quickly bring into line the hand movement and space of the tungsten. Next, push the torch forward to the filler metal. Ensure the filler rod is on the edge of the puddle for easy control. Use one hand to dab the filler metal, and the other remains steady. Do not deposit the filler metal while striking an arc.

Step 3Puddle control

Since aluminum absorbs heat fast, it’s essential to find the puddle and control it. Do not add the filler metal while doing this. Once the aluminum gets too hot, maintain the puddle width by slowly releasing the foot pedal. The reason for this is that too much heat tends to wash out the puddle fast. Easing on the foot pedal is the key to control the sinking heat. On the same line, less heat makes the arc erratic. Practice the art of maintaining speed by laying the puddle down without the filler.

Step 4: Adding the Filler Metal

Consistency is the key when introducing the filler metal. In a dab and move wave, slowly add the filler to the puddle. Avoid unnecessary torch movements when introducing as this creates the bead shape. Once you take control of the puddle, introduce the filler metal the margin. Create your rhythm at the same time you do it on the movement. Provided you keep a steady rhythm with consistent torch movement, the results will be impeccable. Keep doing this over and over again for perfect weld beads.

When Do You Need a TIG Welder for Aluminum?

If you need to create a clean edge on your aluminum, or need to join metal and aluminum together, then you'll need a TIG welder. These welds are necessary if you're repairing sheet metal.

A TIG welder works well with aluminum because its silvery surface can be cleaned, and it's difficult to burn.

However, some welders have a hard time creating a strong joint with aluminum because of the poor heat conductivity of this type of metal. This is especially true if you're welding pieces together that aren't overlapped or connected.

If you're a beginner, then you might want to consider buying an aluminum TIG welder that doesn't have gas controls. This makes your machine easier to use because it eliminates an entire set of controls. You can choose between a manual or automatic mode for joining pieces together, and this should give you the confidence needed to create clean welds.

What is a shielding gas for TIG welders? Why is it important?

Shielding gas is a gas that protects the tungsten electrode and molten weld puddle from the atmosphere. The shielding gas is often an inert gas such as argon or helium because these are chemically stable and inert to most other elements.

For instance, if a welder is welding stainless steel, his/her goal would be to create low carbon steel without any other alloying metals in it. The oxygen in the atmosphere could cause issues when welding this type of steel. The oxygen could react with some of the metal oxides on the surface of the metal which would reduce its effectiveness, cause corrosion, or even make it brittle. A shielding gas prevents this by keeping most of the atmospheric gases away from our weld area.

What are some common problems encountered when TIG welding aluminum?

The common problems that are encountered when TIG welding aluminum are: the difficulty of starting the weld, overheating the weld pool, and hot cracking.

You must use a proper mix of shielding gas that is rich in argon and has helium added to it to reduce the heat input into the weld puddle. If you are using a direct current TIG process, try increasing your travel speed and make sure that your torch angle is correct for aluminum.


A good welder can meet all your welding needs. It not only makes the work more comfortable but also enjoyable. Picking the best aluminum TIG welder for the money is a critical decision that requires commitment. While it may take much of your time, its always worth the effort, well, now you can figure out the right approach to make the best choice.

[sc_fs_multi_faq headline-0="h3" question-0="What Gas To Use For TIG Welding Aluminum?" answer-0="Pure argon is a suitable gas to use. Unlike helium, argon is less expensive and makes it easier to clean the arc. Also, this gas is sufficient as it contains no oxygen that may oxidize the aluminum. TIG welding aluminum is a bit more tricky than welding steel, because aluminum has a much higher thermal conductivity. This means that it conducts heat away from the weld area much more quickly, which can make it difficult to create a strong, consistent weld.

There are a few things you can do to help offset this, though. First, make sure you're using a gas that has a high enough flow rate. This will help to keep the weld area cooler and prevent the heat from dissipating too quickly.

Argon is the most common gas used for TIG welding aluminum, and it generally works well. If you're having trouble getting a consistent weld, though, you may want to try using helium. Helium has a much higher flow rate than argon, which can help to keep the weld area cooler and improve the quality of your welds.

Another thing to keep in mind when TIG welding aluminum is that you'll need to use a different electrode than you would for welding steel. Aluminum requires the use of a pure tungsten electrode, rather than the thoriated tungsten electrode that's common for welding steel.

Thoriated tungsten can actually contaminate the weld area when used on aluminum, so it's important to make sure you're using the right electrode. Pure tungsten gives off less contamination and helps to create a stronger, more consistent weld.

Finally, you'll need to use a lower welding current when TIG welding aluminum than you would for welding steel. This is because aluminum has a lower melting point than steel, so you need to use less heat to weld it.

If you use too much heat, you'll actually end up melting the base metal, which will weaken the weld. By using a lower welding current, you can help to prevent this from happening and create a stronger, more consistent weld." image-0="" headline-1="h3" question-1="What Polarity For TIG Welding Aluminum?" answer-1="TIG welding uses straight polarity or the DC electrode negative for the latest models. The work is set at positive while the torch connection remains negative. The torch serves to prevent excess heat on the tungsten." image-1="" headline-2="h3" question-2="What Kind Of TIG Welder For Aluminum?" answer-2="The needs of certain applications and the skills of the welder are the main determinants of the welding method used on aluminum. With high conductivity and low melting point, aluminum is soft and can easily twist in a feeder." image-2="" headline-3="h3" question-3="How To Clean Aluminum For TIG Welding?" answer-3="Simple! First, remove oils. Second, clean the oxide. Use organic cleaners such as soap to remove the oil quickly. The oxides can be removed using an acid or a steel wire. Finally, dry the aluminum." image-3="" headline-4="h3" question-4="Can You TIG Weld Cast Aluminum?" answer-4="Yes! However, you must first consider the composition of the particular casting. Also, check on how the castings were created." image-4="" count="5" html="true" css_class=""]
