Lincoln Electric K5255-1 Flux-Core Welder: 120 V

What it welds

The Lincoln Electric K5255-1 Flux-Core Welder is a flux-core only on 120-volt input; its listing doesn't state an output range, so check the rating plate.

The maker's thickness claim reads "welds up to 1/4"".

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.

As a flux-core machine it runs self-shielded wire with no gas bottle, which suits outdoor work; expect slag to chip off and less finesse on thin sheet.

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 10 for most of this machine's range. Full table.

Also on the listing: a weight of 15 lb.

Warranty, per the listing: 12 months.
