drag gun thermal dynamic plasma cutter

You need a BIG HEAVY EXPENSIVE plasma unit to cut much of anything.

"I should have known better" but I bought the HorridFreight 600 dollar cutter. Junk.

You really push it to cut, let's say, 5/16" material, and the torch parts are very lightweight, plan on buying a lot of torch consumables.

I later found a Thermal Dynamics unit used for 500 and it works well

Mine is called a "Cutmaster 51" and I believe it was 12--1500 bucks new, originally. It's rated for "genuine cut" of 1/2" and "maximum" of 5/8. This is a big, heavy unit, and requires 220V

That unit you are looking at...............if all you want is sheet metal, "maybe."
