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

Product Description

The LINCOLN ELECTRIC K5255-1 is a portable, single-phase flux core wire welder designed for light-duty MIG-style welding on 120-volt household current. It delivers an output range of 20 to 120 amps with an open circuit voltage of 46 volts, making it suitable for welding mild steel with gasless flux-cored wire in diameters from .030 to .035 inches. The unit operates on a 30 percent duty cycle and is built for hand-held portability, measuring 13.6 inches in length, 8.9 inches in width, and 18.1 inches in height. At 18 pounds, it is light enough for field transport. Licensed electricians, welding contractors, and experienced tradespeople are the typical installers.

The K5255-1 is suited for residential repair work, light fabrication, and maintenance welding where a 120-volt outlet is available. It uses gasless flux-cored wire, eliminating the need for a separate shielding gas cylinder, which simplifies setup in outdoor or field environments. The welder ships complete with a gun and 10-foot cable, ground clamp with 6-foot cable, .030 and .035 contact tips, a gasless nozzle, and a drive roll configured for flux-cored welding. An instruction manual is also included. This unit is CSA certified and carries UNSPSC code 23271408.

Installation Notes

Installation and operation should be performed by qualified welding personnel familiar with applicable electrical and safety codes. Before servicing or changing wire, disconnect the unit from the 120-volt power source. Always verify the outlet and circuit breaker rating are adequate for the unit's input amperage draw before connecting. Follow all applicable ANSI and AWS safety guidelines for personal protective equipment and ventilation when welding with flux-cored wire.
