ARCCAPTAIN 205A DC TIG Welder: up to 205 A, 120 V

What it welds

The ARCCAPTAIN 205A DC TIG Welder is a DC TIG with a maker-stated output of up to 205 amps on 120-volt input.

By Miller's rule of thumb of 1 amp per 0.001 inch of steel, 205 amps reaches about 0.205 in in a single pass. Amps by thickness.

The listing doesn't give a duty cycle with its amperage, which makes long beads hard to plan; the rating plate or manual should state it. Why it matters.

Processes, per the maker: ARC/Lift TIG. Most multi-process machines' TIG is DC lift-arc, so no aluminium unless AC is stated. Choosing a process.

It's DC TIG: steel, stainless and chromoly, but not aluminium.

Household 120-volt power caps its output; check the circuit size the manual asks for. What input voltage changes.

Use a lens of at least OSHA's minimum shade for the current: shade 8 or darker for typical TIG or stick work here. Shade chart.

Also on the listing: a weight of 14.52 lb.

Warranty, per the listing: 3 Years.
