Forney Easy Weld 100ST DC TIG Welder: 120 V

What it welds

The Forney Easy Weld 100ST DC TIG Welder is a DC TIG on 120-volt input; its listing doesn't state an output range, so check the rating plate.

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: Stick and TIG. 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.

A 120-volt machine runs from a household circuit, usually a 20-amp one per the manual. 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: a weight of 13.7 lb.

Warranty, per the listing: 12 month warranty against manufacturer defect.
