Invertec® V155-S 120/230/1/50/60
Portable. Professional. Rugged. Affordable.

Product Number:  K2605-1

The NEW Invertec® V155-S offers much more than you would expect from a welder this size. Weighing in at just under 15 lbs. (6.8 kg) the Invertec® V155-S is no lightweight contender. It packs the full punch of a heavyweight professional that you can take to the most demanding job sites. With 120/230V auto reconnect operation, the Invertec® V155-S can operate from a portable generator. It can also plug into a 200 foot (61 m) 230V extension cord (not included) so you can weld just about anywhere. The tough dent resistant case is IP23 rated for outdoor use.

Backed by a 3-Year Lincoln warranty, this tough reliable welder is packed with innovative unique features like built-in Hot-Start™, Auto Adaptive Arc Force™, stick soft, stick crisp and Touch Start TIG® DC modes. The Invertec® V155-S is available in two models: a base unit with stick accessories or a complete Stick/TIG ready to weld package in an Easy-Store/Easy-Carry Suitcase.
