7. Hobart 500565 Airforce 27i 240-Volt Plasma Cutter

Best Plasma Cutter for Stainless Steel

Okay, so we’ve saved the most expensive plasma cutter until last. This Hobart model is excellent at cutting stainless steel to a thickness of 0.625 inches. What is also impressive about this cutter is that it has wind tunnel technology, which prevents particles and dust from damaging the internal components.

The cost may be prohibitive to some, leading us to conclude this plasma cutter will interest the professional and experienced fabricator market rather than the hobbyists. That said, it does have a multi-voltage power supply, so it caters to 120 and 240 volts.

The fan-on-demand feature kicks in when dust or debris are in danger of clogging the internal components.

What We Like

It can slice through stainless steel like a knife through butter. Depths of 0.625 inches are impressive, meaning you can work on sheet material and thicker metal, increasing your cutting prowess.

Lasts a Lifetime

Hobart welders and plasma cutters are renowned for their quality and resilience, and this model is no exception. If you want to spend a little more to get the plasma cutter of your dreams, you should look at Hobart.

Dual-Voltage Plug

This is very much a professional tool, but there is no reason you can’t use this at home. The dual voltage plug allows you to access the domestic power supply for home and workshop use and then switch to 240 volts when you are back on the job site.

What We Don't Like

Incredibly Expensive

There is no escaping that price. This is truly an eye-watering sum to spend on a plasma cutter. We know they are good, but that good? Reputation is everything, and Hobart is literally banking on theirs.

What Is a Plasma Cutter?

A plasma cutter is a tool that utilizes gas to send an electric arc through a constricted opening, located on the end of a torch. The gas can be argon, air, or nitrogen, and it elevates the temperature, helping the cutter achieve the 4th state of matter. Whoa! Now we’re getting heavy.

The 4th state of matter is neither gas, liquid or solid. It is the state when there is the same number of positive and negatively charged particles produced when the atoms in the gas ionize. It is more common than you think. Plasma naturally occurs on the surface of the sun, and 99 percent of visible matter in the universe is thanks to plasma.

Plasma is produced naturally everywhere, except on earth.

What Does a Plasma Cutter Run Off?

Plasma cutters use electricity to form the arc, and gas is added to increase the intensity of the heat to make metal-cutting possible. You also need an air compressor, unless your cutter unit has one built-in.

What Should I Look for When Buying a Plasma Cutter?

Plasma cutters are a great addition to any fabricator’s arsenal of tools, but what should you look for when shopping for a plasma cutter. Here are the most important considerations.

What Are You Cutting?

The type of cutting you undertake is the biggest consideration. If you are cutting through sheet metal, you don’t need a 200-amp machine designed to cut 0.75-inch steel. You could get away with a smaller, less expensive plasma cutter that runs on 110 volts.

Equally, if you are cutting thicker material, you should try and max-out the amps and get the most powerful cutter you can.

Compressor or Built-In Air Source

Some cutters have built-in compressors, negating the need to purchase a separate compressor. These are more expensive but you don’t have to pay extra for a compressor. If you have to buy an air compressor, mitigate the expense by getting one that can adapt to power spray guns and air tools.

What About the Power?

Power levels are also important because the smaller, 110/120-volt machines produce less impact than the larger, 230/240-volt cutters. This is another factor in deciding what type of cutter to get. The simple answer is to opt for a dual voltage machine; then you can switch between 110 and 240 volts to adapt to the thickness of the material.

Look for Advanced Features

Some plasma cutters are better than others. There are a few convenient features that make life that bit easier.

  • Arc Starting: Some machines start the arc by touching the base metal while others drag the torch like a scratch start on a welder. Beware when buying no-touch varieties as they can interfere with electrical devices like tablets and smartphones.
  • Air-Flow Adjustment: Having the ability to adjust the air-flow means you can continue to flow air when cooling the metal. You can get automatic adjustments as well as manual.
  • Automatic Settings: Some cutters have computerized controls that detect changes in conditions and adjust the temperature and electrical current setting to accommodate. Others have a factory setting that you preselect before you start cutting.
  • Automatic Arc Restrike: This function allows the torch to cut across large gaps in the metal. Electromagnetic sensors detect changes in the metal surface being cut, and shut the torch off automatically as you pass over the opening, and restrike when you are over metal again.

How Much Do You Spend?

The budget is always one of the most crucial factors when choosing anything new. Plasma cutters are expensive, and so you need to make sure your dollars get you the very best machine you can. Research is the key, and knowing what you will use the device to cut brings us back to the very first point.

How Long Is the Warranty?

The warranty is the ideal way to test the manufacturer’s faith in its product. Longer warranties indicate that they are confident the machine will last the distance, whereas shorter guarantees usually mean the opposite.

How Do You Use a Plasma Cutter?

Here is a simple to follow guide to using a plasma cutter. It is not the definitive version. For this exercise, we’ll assume you will need an external air compressor.

1. Connect the Air

Recede the flange of the outer flange of the female connection and connect the male section. This ensures there is enough air-flow to keep the plasma stream under sufficient pressure. Now plug the machine in and turn on the air.

2. Ground Clamp

Attach the ground clamp to the base metal to create the circuit. Now turn on the machine.

3. Set the Current

For this exercise, we will set it to 25 amps for 18-gauge sheet metal.

4. Cut the Metal

Activate the plasma cutter by depressing the trigger. You need to lift the safety before pressing the trigger. Keep the cutter end of the torch close to the material and make the cut. Take care to move slowly but steadily.

5. Power Off

Always switch the cutter off and unplug it to make sure no accidents occur. And don’t forget to disconnect the ground clamp. Now turn off the air and disconnect.

Plasma Cutters FAQs

Do You Need Gas for a Plasma Cutter?

You need gas to maintain pressure on the plasma stream and increase the heat as it flows through the narrow opening. You can use air, argon or nitrogen.

Is a Plasma Cutter Better Than a Torch?

Plasma cutters outperform torches because you don’t need to preheat the metal before cutting, and you can cut in greater detail for fine lines. Also, plasma cutters cut stacked metal more efficiently, which can speed up your work rate.

What Size Air Compressor Do I Need for a Plasma Cutter?

You should get an air compressor rated at 1.5 times the cubic feet per minute of your plasma cutter. When it comes to plasma cutters, the golden rule is the bigger the compressor, the better.

How Thick Can a 50-Amp Plasma Cutter Cut?

A 50-amp plasma cutter typically cuts approximately 1-inch deep, but this does vary depending on the material you are working on.

Can You Cut Wood With a Plasma Cutter?

The short answer is no. You need the material to be electrically conductive. Unfortunately, wood is not conductive, and so cannot be plasma cut.

Making the Cut

Which plasma cutter is right for you is down to personal choice. Budget, cutting prowess, and what type of material you are cutting all have roles to play. The best plasma cutter isn’t necessarily the most expensive, nor is the cheapest the worst.

Value for money is a personal thing. Do your research and make sure you get it right when you make your choice.
