Lincoln Electric K1170 Stick Welder: 120 V

What it welds

The Lincoln Electric K1170 Stick Welder is a stick inverter 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.

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: dimensions of 14.75 x 18.75 x 26.38 inches; 99 pounds and a weight of 99 lb.

Warranty, per the listing: Manufacturer Warranty.
