Lincoln Electric K5256-1 MIG Welder: 120 V

What it welds

The Lincoln Electric K5256-1 MIG Welder is a MIG / gas 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: MIG and Flux Core. Most multi-process machines' TIG is DC lift-arc, so no aluminium unless AC is stated. Choosing a process.

It runs solid wire under shielding gas for the cleanest wire-feed welds; most machines like it also run flux-core wire outdoors.

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 10 or darker for typical MIG work here. Shade chart.

Also on the listing: a weight of 19 lb.

Warranty, per the listing: 1 year.
