What is the purpose of a spool gun?
The spool gun has been well designed to help connect to the HIT140/MMIG140 only. It can be used on feeding wires that are very difficult to feed using the standard MIG torch. In most cases, this is usually used for aluminum wires although any wire type can be used. The spoon guns will help in improving the feed ability of the aluminum wire.
How do you weld Aluminum with a spool gun?
Here are steps that will guide you on welding aluminum using a spool gun.
- Clean the Metal
It is possible to weld at times without cleaning the metal especially when it is new or does not have any residues on it. It is always appropriate to start your aluminum welding using a spool gun by cleaning the metal using an angle grinder or a wire brush.
- Welding Angle
In most cases, a 10-15 degree angle will ensure a job is effectively done. As is the case with most welding projects, when you get this wrong, there could be more problems with the weld than you could experience when welding steel. Attention to detail is very important when you are maintaining the right angle.
- Set Wire speed and voltage for Aluminum welding
The wire speed and amperage are the first places you can start with your adjustments before you start welding aluminum. Lots of heat and too much wire will do a number on the weld and leave you with lots of mess to clean up. Make use of the chart that comes with the welder so as you can experiment with a few different voltages and wire speed settings before you start working.
- Use a Gas Flow for Aluminum Mig welding
In case the arc is hissing too much or jumping around, there is a better chance you will have to adjust the gas flow shielding. Lots of shielding gas will always cool off the weld puddle.
- Check metal temperature for welding Mig Aluminum
You can consider preheating the aluminum as it will give you a neater and cleaner weld. In case you are working on a cold climate, ensure you consider preheating the metal before you strike the arc.
- Keep testing the settings
Even the experts will always have to conduct a number of tests to ensure they get the right welding setting. No one will want to cover their welding work with burn or spatter. This is why you need to always test the gas flow, stick out length, and burn up speed and the amperage.
How To Choose The Best Spool Gun For Aluminum Welding?
There are a number of things you need to consider when shopping for the best spool gun for aluminum welding in the market.
- Material Quality
Before you settle on any spool gun, it is important that you check on the quality of materials used in making the product. For instance, a higher quality of MIG welder will work quickly and more efficiently.
Top quality material is made using heavy duty materials. Some of the quality materials used in making a spool gun is stainless steel, aluminum, iron and mild steel.
- Wire Size
It is highly advisable that you are aware of the wire size and the type of material used in making the wire. Determining the width and length of the wire is important. It does not matter if you are a hobbyist or a professional, it is important that you always have a great idea about the wire speed, diameter and type of material used.
- Power Supply
The Spool guns are known to work by consuming power while feeding wire electrode to help in creating heat that will attach the metal. Power supply is usually categorized into two types. There is the input and output power. Most of the spool guns are known to use constant voltage power supply.
The industry level welding will require higher input power to enable it melt the heavy duty metals quickly. Considering the material thickness, input power will need to be adjusted always.
- Duty Cycle
Duty cycle refers to the time limit that will help prevent overheating. Overheating is capable of over melting and changing the metal. Depending on the type of metal and heat amount, always check if you can adjust the heat and set a time limit. The duty cycle feature will help you to automatically control the temperature. In most cases, an ordinary pool gun will have a 10 minutes duty cycle.
- Controls
Any typical spool gun will comprise of a power cable, control switch and an electrode conduit. Always go for a spool gun that has fewer manual control and more controls that are automatic which will enable you have an easier work.
Most of the machines today have been designed to have more of the automatic controls that can work fast and are simple to use. In case you are a newbie, the automatic controls will be very easy to use and help save your time and energy.
- Size and Weight
Size and weight of the spool gun do matter as it will determine if the machine is versatile and portable. It is advisable to always go for a machine that weighs lesser if you will be using it from your home or on simple projects. However, the industrial level spool guns need to be made of heavy duty materials which make them quite heavy.
Go for a machine of reasonable size which you can easily transport and store in case it is not in use.
- Durability
No one will want to get back to the market a few weeks after spending lots of cash to get a new best spool gun for aluminum welding. It is important that you check on how durable the machine is. You can determine this by looking at the quality and type of materials used in making it.
Price and warranty period will also help tell if the spool gun is durable or not. Spool guns that are very cheap in most cases never last for long due to the quality of materials used in making them. Spool guns with short warranty period are in most cases not that durable.
- Wire Feed Speed
The spool gun wire feed speed is an important aspect since it decides how accurate and fast welding can be done. Different welders are known to have different wire feed speed. You can always make your choice depending on your preferences.

FAQ
Do you have to use a spool gun to weld aluminum?
For successful welding of aluminum, you need a very stable arc. Spool gun do have a short feed distance that offers a reliable and steady feet. Having a smooth feed to weld is one of the key things behind getting a smooth arc.
What welder is best for aluminum?
MIG welding is widely known to be best when it comes to dealing with thinner aluminum sheet gauges. This is due to the amount of heat required. When you are selecting a shielding gas, 100% argon is considered as the best for MIG welding aluminum.
What gas do I use for aluminum spool gun?
Since aluminum is a non ferrous metal, it does require a 100% argon shielding gas.
Can you use 75/25 to weld aluminum?
75/25 basically means 75% of Argon while the remaining 25% is CO2. Pure argon will always give perfect results when it comes to aluminum welding. It is very possible to use 75/25 in welding on aluminum.
How many amps do you need to weld aluminum?
When welding aluminum, it is advisable that you use 1 amp for every 0.001 of material thickness. This means that the material welding base is 1/8 inches thick will need about 125 amps.
What polarity do you need to stick weld aluminum?
When it comes to stick welding of aluminum, the DC+ polarity is most often used. It will always produce a better bead profile with a much higher penetration level.
Can all TIG welders weld aluminum?
The most basic method of welding aluminum is TIG welding. Any TIG welder is capable of welding aluminum.
