Plasma Cutter Buying Guide
Torch Type

The torch model on a listing tells you more than it looks like it does. It signals the machine's amperage class, how ergonomic the cutting will feel, and — most importantly — how easily and cheaply you'll find replacement consumables three years from now. Consumables are a recurring cost; the torch determines that cost.

  • PT31 — The classic budget contact-start torch, typically paired with 30–40 A machines. Consumables are everywhere and dirt cheap, but it's a contact-start design, so tip life is shorter and it can struggle on rough or coated material.
  • AG60 — Probably the most common torch on affordable pilot-arc machines up to about 60 A. Consumables are inexpensive and widely stocked on Amazon, and the pilot arc handles rust and expanded metal well. A safe, practical choice for the average buyer.
  • IPT40 — A compact, comfortable torch for roughly 40 A machines, favored for detail work and tight access. Good ergonomics and generally decent consumable availability.
  • IPT60 — The 60 A sibling: a bit more capable, still comfortable, and common on mid-range machines. A solid middle-ground option for general shop work.
  • P80 — A heavier 80 A torch built for thicker plate. Bulkier in hand and less suited to delicate work, but it handles sustained cutting on heavy material without complaint.
  • SG55 — A widely used 50–55 A torch found on many imported machines. Consumables are cheap and plentiful, though quality varies significantly by supplier — buy from the machine's manufacturer when you can.
  • PT80 — A common 80 A workhorse torch for fabrication-class machines. Robust, well-supported, and a familiar sight in production shops.
  • PT100 — Heavy industrial torch for 100 A and up. Built for thick plate and long cuts; overkill for anything a home shop is likely to do.

Before buying, search Amazon for that torch's consumable kits and check price and availability. A cheap machine with an obscure proprietary torch stops being cheap the first time you need tips and electrodes and can only get them from one seller.

Frequently Asked Questions
Expect to spend $250 to $500 for a capable entry-level machine that will handle most home garage work, $600 to $1,200 for a mid-range fabrication-class cutter, and $1,500 and up for premium American-made units. The purchase price isn't the whole story, though — consumables are a recurring cost, and a cheap machine with expensive or hard-to-find tips can end up costing more over a few years than a better cutter would have. Budget an extra $50 to $100 for a spare consumable kit right at the start.

Buy a machine rated to cut about twice the thickness you work with most often. If you mainly cut sheet metal and 1/8 in stock, a 40 A machine is plenty; if you regularly work with 1/4 in to 1/2 in plate, look at 45 to 60 A. Running a cutter at the absolute edge of its rating means slow, dirty cuts and rapid consumable wear, so a little headroom pays for itself.

Often, yes. Machines above roughly 45 A generally need a 220/240 V outlet, typically a NEMA 6-50, which may mean hiring an electrician if your garage doesn't have one. Dual-voltage machines are the popular workaround — they run on a standard 110 V household outlet for lighter work and switch to 220 V for full power. Just check the required breaker amperage before buying, because the outlet is usually the more expensive part.

Most plasma cutters require an external air compressor, and the listing will specify a CFM at PSI requirement — commonly somewhere in the range of 3.5 to 7 CFM at 60 to 90 PSI. Your compressor needs to deliver that continuously, not just in short bursts. If you don't own a compressor and don't want one, look for a machine with a built-in compressor, but understand that those trade away cutting capacity and duty cycle for the convenience.

For occasional light work, many of them genuinely are. Value brands can deliver solid performance at a fraction of premium pricing, and plenty of home shops run them for years without issue. The real trade-offs are inconsistent quality control, thinner customer support, and consumable availability — so before buying, search for that machine's torch type and confirm replacement tips and electrodes are cheap and readily stocked.

Was this helpful?

For most buyers, yes. A pilot arc lets the machine start cutting without the tip touching the metal, which dramatically extends consumable life and makes cutting rusted, painted, or expanded metal far easier. Contact-start machines are cheaper and fine for clean plate, but if you'll be cutting grating, farm equipment, or anything less than pristine, the pilot arc is usually the single best upgrade for the money.

Rated cut (sometimes called quality cut) is the thickness a machine cuts cleanly at a reasonable speed. Sever cut is the absolute maximum it can burn through — slowly, with a rough edge and heavy dross you'll spend real time grinding off. The big headline number on Amazon listings is usually the sever cut, so shop by the rated figure and treat the sever number as a technicality rather than a capability.

If your shop does a bit of everything and space is tight, a combo unit that pairs plasma cutting with TIG or stick welding offers excellent value and saves floor space. The trade-off is that combo machines rarely match a dedicated cutter at any single process, and a fault takes all your capabilities offline at once. If cutting is your primary need or you cut daily, a dedicated machine is the better long-term buy.
