01. Cutting Mechanism:
Hobart Airforce 27i can be used to cut different types of steel and aluminum thanks to its amperage settings. You set the amperage to suit the type of metal that you are cutting.
With the machine, you will be able to cut not just thin sheets of metal but 3/8″ and sever 5/8″ steel plate.
You can use the Hobart Airforce 27i to cut different types of metal. You need to set the amperage setting on this machine depending on the type of metal you are cutting.
If it is thin, then set it for lower amperage. If it is thicker, like 3/8" or 5/8", then you need higher amperage.
This way, not only will you get a clean cut but also save time when building your project.
02. Inverter Technology
This technology is one of the best. It makes Hobart 27i one of the most economical cutting machines.
You can compare the input current that it draws with the power output, and you will see that this machine is very effective.
It offers more power than other models but weighs half as much.
03. Amp Ratting
The 27i is a very powerful machine that comes with a rating of 27 amps maximum output for 240V and can cut 3/8″ steel.
You might find that a 27 amp machine can cut 5/8″ steel. BUT it will go very slowly. If you need to cut 5/8″ steel, then use the 27 amp machine.
This machine can be turned up to 20 amps. At 20 amps, you can cut a maximum thickness of 1/2 inch metal. It will not be fast, but it is doable.
04. Perfect Clean Cut
According to the manufacturer, the Hobart 27i can only cut cleanly up to 3/8 of an inch. If you want to cut a piece of half-inch steel with this machine and thickness rating is greater than its maximum size, it will sever through the metal but not be as neat in cutting straight without slag build-up on the bottom or slower speed movement while operating.
Just remember that these ratings are for the best conditions and we often push past those. The machine will not break if you do, but it won't provide a nice, clean-cut cut.
05. Duty Cycle
The unit's rated output is 27 amps at a 35% duty cycle. That means it could only be used for 3.5 minutes out of 10.
But if you are cutting 16 AWG metal at full capacity, you can cut up to 56 feet of metal at 80% capacity.
On the other hand, If you are cutting a 1/2 inch thick piece of steel, it will take 21 inches for the machine to need a break before continuing.
If you are cutting a 1/4 inch thick piece of steel, it will only take 82 inches before the machine needs a break. When cutting, it usually takes about one minute to reposition if all goes well.
In that time, you will be able to cut an eight-foot long 1/4 inch thick steel piece with three repositions without having the 27i shut off. This is not the best way to do things, but it shows that 1/4 inch steel can be cut with a 27i without too much trouble.
06. Pilot Arc
The Hobart 27i has a pilot arc, but it isn't the full-blown pilot arc you would see with a machine in this price range.
It is just starting to have a pilot only. When you start cutting, it will act like it has a pilot and turn on the torch's arc. However, if you don't cut anything for a while after starting your process, then it will stop working.
You need to cut something every so often for about 5 minutes or so; otherwise, the machine will stop and you'll have to start over with another piece of metal.
07. Easier to store and move
Your old cutting machine is big and heavy. You cannot find a place to put it. It might be hard to move it around or put it in the place you want it. This new model is 50% smaller so you will be able to find a space for your machine easier. It weighs 30% less than the previous model, so moving your machine will also be easier.
08. Dual-Voltage capability with MVP (Multi-Voltage Plug)
This is a machine that can plug into a regular outlet and also plug into a power outlet with more power. It is good for when people do not have enough power in their house.
The machine would be used when someone needs to cut through metal and needs more power than the regular outlet provides.
This machine has an option for 120v or 240v, but it will work better with 240v because 120v does not give the full amount of power to this machine.
This plug lets you use power at most places without any tools. Choose the one that fits the place.
09. XT30R torch
XT30R torch design for increased comfort. It has ergonomic trigger safety, more efficient cooling, and economical replacement cutting tips. The Hobart Replacement Plasma Cutter Tips for XT30R Series Plasma Torch is designed to work with the Hobart AirForce 27i plasma cutter for running at optimum efficiency.
10. Wind Tunnel Technology™ and Fan-On-Demand™
When there are lots of dust or metal shavings in the air, it can be hard for machines to work. But the Hobart Airforce 27i plasma cutter has Wind Tunnel Technology™ and Fan-On-Demand™ that makes them works better.
Wind Tunnel Technology is a way to cool the machine without blowing over the electronic parts. This way, you don't have dust from grinding settle on your important parts.
Fan-On-Demand means that the fan only runs when it is needed. This reduces the amount of dust coming out of the machine. The air supply for hand-held plasma cutters is usually ordinary air.
In mobile applications, contractors often use bottled nitrogen. Nitrogen is cheaper than air and also less wet than compressed air. Nitrogen is used to cut metal and some people believe that it produces less oxygen than compressed air, which makes it better for cutting steel.
11. Power factor correction (PFC) circuitry and LVC™ line voltage compensation
The Hobart 27i plasma cutter has a technology called Power Factor Correction. Using power semiconductors chops the DC into a higher frequency and higher voltage.
The current is then stored in a much smaller coil. This means that the inverter plasma cutters with PFC have PF numbers close to unity (1).
It draws 30% less amperage than other machines for the same work. When you use an extension cord, the PFC will help you to do work. It also won't make the circuit breaker trip like it does when there is low voltage.
12. Safety and Cooling
You can use this machine because it has a lot of great features. It will not overheat and you cannot accidentally press the trigger to cut anything, so there's nothing that could go wrong!
In addition, if your machine starts overheating or too hot for some reason but still really needs to be used until it cools down again - as long as you're careful about how much work is being done on the machine at any given time--it won't happen. There are also two things that help with cooling: post-flow air cooling after cutting metal pieces; wind tunnel cooling helps keep dust out from going into your equipment while additionally ensuring quick temperature drops when needed most.
13. Compatible with engine-driven welders
When you have an engine-driven welder, you can cut anything. It is the best way to do work quickly and well. No matter what size job, it will be done better with an engine-driven welder/generator paired up with a 240V receptacle of 4 kW or more.
