What it welds
The Everlast Power Equipment PowerArc161STH DC TIG Welder is a DC TIG with a maker-stated output of up to 140 amps on 240-volt input.
Miller's starting rule, 1 amp for each 0.001 inch of steel, puts 140 amps at roughly 0.140 in of steel in one pass; thicker work means bevels and more passes. Run the amperage selector.
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: tig & stick. Check which torches and guns come in the box; a TIG torch or spool gun is often extra. Process guide.
It's DC TIG: steel, stainless and chromoly, but not aluminium.
It needs a 240-volt circuit; have a licensed electrician install the receptacle the manual specifies. 120 V vs 240 V.
Eye protection: OSHA's minimum is shade 8 for most of this machine's range (shade 10 for stick above 160 A). Full table.
Also on the listing: dimensions of 20 x 12.5 x 13.5 inches and a weight of 30.9 lb.
