This wiki has been updated 13 times since it was first published in February of 2018. Most people are familiar with solids, liquids, and gases, but there is an additional form of matter that is especially useful for cutting metal. A powerful alternative to oxyacetylene torches, plasma cutters use a strong burst of electricity to turn pressurized air into an incredibly hot arc. They can slice through steel up to about an inch thick, and some also allow for TIG and stick welding. When users buy our independently chosen editorial recommendations, we may earn commissions to help fund the Wiki. Skip to the best plasma cutter on Amazon.

Editor's Notes

May 12, 2019:

Plasma cutters can be simple, drag-operated units that don't cost much, or fancy, pilot-arcing devices suited for professional use. The hallmark of either, though, is resilient and reliable wiring inside. If you only need to cut things occasionally, the Lotos 3500 and PrimeWeld CUT50 are tough to beat, because they're remarkably inexpensive, though they don't leave the cleanest edges. The PrimeWeld CT520, another affordable option, is an all-in-one choice for those who undergo a lot of welding as well. Clear on the other end of the slicing-only spectrum are the Hobart, Miller, and Powermax 30, which are designed for contactless operation and suited for full-time use by the most skilled workers. They're awfully expensive, though.

Some of the most worth checking out, however, are in the middle of road. The Lotos 5000 is one of the most affordable pilot arc models, while the PrimeWeld CUT60 is almost impossible to beat in terms of price to performance. And at right around $1000, the AHP and Everlast both perform at a level nearly equal with those twice as expensive.
