1. PRIMEWELD Premium & Rugged 50A

Image of the PrimeWeld 50D

Some cheap plasma cutters just aren’t up to the job but this is a high-quality dual voltage model that will provide serious value for money.

It uses a high-frequency DC current that will cut through thicker materials than the average cutter and with a greater level of cut quality too. The 60% duty cycle is very reasonable too.

It’s very easy to operate and you should have no problems setting up this quality plasma cutter and you can be assured it will get the job done.

Though I’d note that if you want to cut thick materials – you might want to crank up the power to 220 Volt input. It is also supported with a decent warranty and comes with some of the best customer support that we’ve seen for welding products.

Finally, at just over 10Kg this unit is relatively portable and you can use it pretty much wherever you have metals to cut. If you want welding functionality, however, you might want to check out its big brother the Primeweld CT520d.

2. SUPER DEAL DC

image of the Superdeal CUT50

If you want a super deal then this SUPER DEAL DC plasma cutter is exactly that. This isn’t the best plasma cutter to choose for a machine shop, it’s clearly aimed at the hobbyist market and has a price tag to match.

But if you want good quality cutting in a very affordable box, this is probably the ideal choice. That’s not to say that this purchase doesn’t have some cons as well as pros.

Firstly, when I took it out of the box – there were no imperial measurements on the table included for working out the power. You can look them up easily but that’s not ideal.

It also doesn’t seem to power down until a few seconds after you switch it off. Ignore that though and it works well. I found the contact tips were fine and that the non-touch pilot arc wasn’t needed for most projects you’re likely to do with this.

3. PRIMEWELD 3-in-1 CT 520D

image of primeweld 3in1 plasma cutter

If you want more than just a plasma cutter and feel like a stick welder and tig welder would come in handy then you should check out this plasma cutter under $500. The Primeweld CT520d is an excellent product.

There’s no non-touch pilot arc but again, for the project’s that you’re working on with this kind of cheap plasma cutter – you probably won’t care very much.

However, it’s a pretty good all-rounder and for TIG Welding I was surprised at the quality of the weld that the Primeweld CT520d produces. It was great working with mild steel.

As for cutting? The cutting speed is fine. I found that the Primeweld CT520d provides a nice clean cut and it’s very easy to use.

It’s quite a heavy-duty model when you compare it to some of the other cutters in our review and that also makes it heavier than some of the other models – at nearly 20 Kg, it is portable but you might want a hand when moving it around.

While it’s not the cheapest machine in my tests, it’s a low-cost option when you consider just how much functionality you can get out of this cutting machine and welding machine.

4. SUNCOO Plasma Cutter Cut 50

image of Suncoo plasma

This cut 50 plasma cutter under $500 comes with a decent but not outstanding 1-year warranty and despite the low price, it’s great for cutting metal.

In my tests, it cut easily through steel alloy, stainless steel, copper, aluminum, brass, and cast iron without any difficulties at all.

In fact, there are very few material specifications that it can’t handle (assuming they are OK to be cut with plasma cutting machines – it doesn’t work miracles).

It will only cut to a maxim of 1/2 inch thickness, so if you need something that will go to 2-inch thickness this won’t get the job done. It will give very easy clean cuts up to near its maximum cut thickness though.

It is fully dual voltage and you get 110 220v input power support as standard and it’s quite easy to drag around as it weighs a very portable 25 lbs.

They use an energy-saving technology that allows the use of fewer consumables and less power, allegedly. Overall, for the price range, this is a solid plasma cutter with a decent duty cycle that will suit any hobbyist and potentially those with light plasma cutter needs in a workshop too.

5. Lotos LT3500

image of LT3500 plasma cutter

Another 110 220v plasma cutting machine is the Lotos LT3500. This is an air plasma cutter than can handle 2/5″ cuts. It is a super cheap plasma cutter that will suit any hobbyist with occasional needs for a plasma cutter that works with their air compressor.

It uses digital inverter technology to provide up to 35 amps of power. To get air pressure you just connect it to the NPT 1/4″ D Plug on your compressor.

The duty cycle isn’t great but it shouldn’t matter too much as long as you’re not expecting high cutting performance levels.

It will cut alloy steel, stainless steel, copper, aluminum, brass, and cast iron, and while you won’t get the best cutting performance compared to more expensive models, on high power the cutting torch is more than good enough to give you cutting power for the jobs you are likely to tackle at home.

In fact, I’d say this is a strong contender for the best cheap plasma cutter on the market. Don’t forget that you will need to buy an air hose separately to attach the source of compressed air, this is a very “basic” model. There’s no air filter in the box, either.

With less expensive models I like to make sure that the customer support is responsive and I can confirm that Lotos deal with any problems you have in a fast and efficient manner.

6. VIVOHOME 3 in 1 Multi-functional Plasma Cutter

image of Vivohome CT520DF Blue

The second, of our 3-in-1 plasma cutters, is the VIVOHOME Model. You won’t get a high cutting speed as with some of the specialist plasma cutters but a severance thickness of 3/4″ is nothing to be sneezed at.

The stick and TIG welding functions are very good and, in fact, the TIG welder side of things was one of the best performances from a cheap welding machine that I’ve seen with a welding current of 200 amps, it’s surprisingly efficient. If you want an easy weld experience this is a great way to go about it.

This is a full non-touch pilot arc plasma cutting solution and it will cut metal easily and consistently.

You can select your own input power with both 110 v and 220 v sources working just fine thanks to the dc inverter technology they use. The duty cycle for all 3 functions won’t break any records but should be more than enough to handle most small jobs too.

As you probably already know, working with a pilot arc plasma cutter can give you a lot of control over the cut and this is what I found with this model.

This is one of the best budget plasma cutting machine options if you want tig/stick support and it’s nice to find an affordable dc tig welder, in particular, included in this very reasonable price. The consumables are also fairly low cost as long as you keep your orders down to what you need rather than trying to lay in large stocks “just in case”. There’s even a 1-year warranty supplied.

7. Goplus CUT-50

image of Goplus CUT-50

Right in the center of the price range for these plasma cutters is the Goplus CUT-50. It needs a constant air pressure of 8.8-11 lbs. which ought to be easy to provide with a home compressor.

It uses dual voltage 110 and 220 volts input sources and works using a high-frequency oscillation drag torch technology to provide a solid level of performance.

The duty cycle is pretty much what you’d expect for something at this price point.

The construction is a little flimsy but we found that it worked fine to cut metals and that’s really all you’re going to be worried about when you buy a system like this. The 50 amp output range is one of the standard features of the best plasma cutters.

I had no problem when cutting mild steel with these cheap plasma cutters and though it would tackle 1/2 inch, it sliced cleanly through 1/8″ as though it wasn’t there.

It was nice to have some consumables in the box with this, though they won’t last long. So, make sure to buy extra materials when you order it. There is also a 1-year warranty provided by the manufacturer. The cut 50 plasma cutter is a solid budget option.

8. ZENY DC Inverter Plasma Cutter 50AMP CUT-50

image of zeny machine

This super cheap plasma cutter was not the best plasma cutter that I tested but it wasn’t bad, either.

The duty cycle of 60% was very much the standard for most plasma cutters in this test group and the pilot arc system worked very well, indeed.

It is also a dual voltage set up and the Zeny Cut 50 is a machine that cuts different materials without any real problems.

One of the big cons of this unit though is that the build quality isn’t great. Another one of the cons is that you won’t receive world-class customer support but let’s be fair about this – this what you pay for with other models.

On the pros side of the equation, this is a 50 amps plasma cutter that does what it says it will on the box. Another pro is that the Zeny Cut 50 comes with a 1-year warranty. Not every plasma cutter does. If you want easy cutting power that slices through metal in occasional work projects? This will do fine, just don’t expect it to last forever.

9. Vipercut 30amp Plasma Cutter

image of the VIPERCUT-30

This unit has an inverter that only produces 30 amps of power and that means a much lower duty cycle than other plasma cutter options.

A 30 amp plasma cutter isn’t quite as puny as you might expect though and it will cut through 3/4″ materials with a little effort and it can handle most metal to a thickness of 1/4″.

One thing I did like about this plasma cutter was that they included a ground clamp in the box and not every plasma cutter manufacturer pays attention to small details like this.

The cutting work on metals that I tested this on was clean and it was no less effective even it was a little slower to start with and required a bit more pressure to finish the job.

For a low-cost unit, this comes with enough features, a passable warranty, that even if it’s not the best plasma cutter ever made, it’s more than good enough as a plasma cutter for a keen hobbyist. The Vipercut 30 is a solid choice.

Frequently Asked Questions [F.A.Q]

What is the difference between air-cooled and water-cooled TIG torches?

A: Yes, in fact, a plasma cutter is quite capable of cutting galvanized steel and it often provides the best finish too. There is, however, a problem – using plasma cutting on this kind of steel will release poisonous smoke that if inhaled will result in “metal fume fever” (thanks to the Zinc in the smoke).

This means that you need to work with plasma and galvanized steel in a very well-ventilated area (consider the use of a respirator) if you want to do this. You might be better off using an angle grinder or reciprocating saw, otherwise as they won’t create anywhere near as many fumes.

Conclusion

As you can see, you have plenty of great value plasma cutter options under $500. In our opinion, the best of them is the PRIMEWELD Premium & Rugged 50 Amps model.

If you want a cheap entry-level plasma model then you might want to go with the LOTOS 3500 which offers impressive plasma cutter technology at a very affordable price.

Alternatively, if you want to add a little more functionality to your home workshop then you could consider the PrimeWeld 3-in-1 CT-520D which brings you a TIG welder and Stick welder for a little extra investment in your plasma cutter.
