Lincoln Invertec 160-T TIG Welder (K1845-1)

Lincoln's Invertec 160-T (model K1845-1) is a compact, 39 lb DC machine built for fabrication or field maintenance work where portability matters as much as having both TIG and Stick in one box.

Who it suits

Weekend warriors who need to move a welder between jobs, rather than leave it bolted to a bench, are the target user here. Integral gas and power connectors keep torch hookups simple, and switching between TIG and Stick welding takes only a quick change rather than a full setup. Despite the small footprint, it's rated to 160A on a 100% duty cycle at 90A (TIG, 115V input) or 100% at 130A (TIG, 230V input), so it isn't limited to light-duty passes.

Features that matter day to day

Selectable touch start gives high-frequency TIG starting across a range of conditions without needing a separate HF box, and a built-in pulsing function adds more control on thin material. This model also auto-reconnects across 115/230V and between 50/60Hz power, cutting out a wiring mistake that trips up less experienced operators. The whole unit packs into a rugged, lightweight case with a fully adjustable shoulder strap for carrying it to the job.

Common questions

What's included? A 115V input cord with plug, a 20A plug adapter, an adapter that mates either the PTA-9 or PTA-17 one-piece torch style, a shoulder strap, and a work clamp with cable. Does it run on both 115V and 230V? Yes, with auto-reconnect handling the switch. This item is sold with a Proposition 65 notice attached, as welding machines commonly are.
