Best Cheap Plasma Cutter Buying Guide

Manual Plasma Cutting

As there are a variety of plasma cutters available today, it can be quite confusing for you to pick one that’s best suited for your needs. That said, there are a few features that you need to consider before going forward with the purchase. Keeping these factors in mind will help you in finding the right tool for your needs.

Here’s a quick buyer’s guide showing you what you should pay attention to before buying a plasma cutter:

Power Source

This is a key factor to consider before you purchase a plasma cutter. These tools can use either electricity or air pressure to cut through metal. While both are equally powerful and feasible for most usage, knowing the power source for the tool is important. If the place you work at has limited electrical outlets, then air pressure models work best.

Regardless of which cutter you go for, it’s also important to know what gas type it needs to run. Also, make sure if the place you work at has 110V/220v power outlets. Moreover, you’ll need to see if the breakers at your workshop have adequate amps to resist the unit’s amperage and also the air compressor.

Duty Cycle

This is another important feature to consider before making your purchase. Simply put, the duty cycle indicates how long the tool can perform under certain loads. Usually, it depends on the welder’s amperage and it comes in a percentage format, which can be found printed on the box.

To purchase plasma cutters with high-performance, you must check the average thickness it can cut through. If you go for one with a low duty cycle, it’ll only run for a limited period. For heavy-duty work, you’re going to need a tool with a higher duty cycle. You’ll be better off with plasma cutters that offer 50-60% duty cycle.


Consumables refer to the parts of the unit that will deteriorate with time. Generally, plasma cutters use 5 different consumables, namely-nozzle, swirl ring, shield, electrode, and retaining cap. The shield safeguards the other consumables from sparks and molten metals. A drag shield will be better if you aren’t familiar with such machines. The retaining cap helps in keeping the consumable stack together. The nozzle’s key role is to focus on the plasma arc.

Similarly, the other consumables have their own functions. The point here is to pick a tool that is compatible with affordable and readily-available consumables.

Plasma Cutter FAQs

Plasma cutting process

In this section, we’ll be answering some of the most commonly asked questions that people have about plasma cutters.

How Hot is a Plasma Cutter?

Plasma cutters can get heated up pretty intensely up to 45,000°F, which is 25,000°C. This is why you’re advised to not look straight into the flame or it may damage your sight permanently.

Can You Cut Aluminum with a Plasma Cutter?

Yes, Plasma cutters can cut aluminum. In fact, you can use it for cutting any conductive metal such as stainless, mild steel, etc. This is because the tool doesn’t depend on oxidation to perform. However, cutting aluminum does pose some unique challenges, particularly concerning chemistry and crack sensitivity. Consequently, you’re required to follow a proper gas selection and cutting technique.

Do Plasma Cutters Use Gas?

Yes, plasma cutters make use of electrically conductive gas for transferring energy to any conductive material from the power supply, which results in a quicker, cleaner cutting process.
