LOTOS LTP5505D Plasma Cutter: 55 A

What it welds

The LOTOS LTP5505D Plasma Cutter is a plasma cutter rated by its maker at up to 55 amps on 110 or 220-volt input.

The listing doesn't state a cut capacity, which is the main way to size a plasma cutter. Makers mix rated, clean and severance figures; compare like with like. Cut capacity explained.

Check the air requirement in the manual; your compressor has to deliver that flow continuously at that pressure.

Arc start: Pilot Arc. Pilot-arc and non-contact starts help on rusty or painted steel and expanded metal.

OSHA's minimum lens for light plasma cutting is shade 8, and its fire rule wants combustibles 35 feet away or shielded. Shade chart.

Also on the listing: dimensions of 10 x 10 x 10 inches and a weight of 16 lb.
