EcoRenovator - View Single Post - I bought a Chinese plasma cutter 50Amp 120/240 Volt.

I would not try to cut anything over about 3/8 inch thick with that unit. The thing might be tough enough to get the job done slowly, but it's really easy to try to make plasma cutters work too hard. Before you know it, you burn an electrode and/or nozzle up, or get flashing lights on the box. Then it's too late. On thicker material, an oxyfuel cutting torch is faster anyway.

For sheet metal and thin plate, plasma cutters rule. They cut better than a jigsaw and faster as well. Very little grinding or sanding is needed after the fact. No extinguishing or restriking like a gas torch. Just pick it up, do what you need to, and set it down. For complex patterns or fabrication of many parts, they really speed up your day.
