The Lincoln Electric Lincoln Invertec V155 Stick Welder is a compact, inverter-based Stick (SMAW) welder designed for professional maintenance, repair, and light fabrication work. Delivering reliable DC output for electrode welding on structural steel, carbon steel pipe, and common alloys, the Invertec V155-S provides the arc stability and portability that field technicians, maintenance welders, and hobbyists depend on.
Lincoln Electric's Invertec line employs advanced inverter technology to deliver smooth, consistent arc performance at a fraction of the weight of traditional transformer-based machines. The V155-S supports a range of stick electrodes including E6010, E6011, E6013, E7018, and E7024, making it versatile across maintenance, repair, and light structural applications. The U2605-1 is a low-hour factory demo unit carrying Lincoln Electric's performance certification at a substantially reduced price.
