Portable. Professional. Rugged. Affordable.

The 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. It features 120/230V auto reconnect operation and can operate from a portable generator. It can also plug into a 200 ft. (61 m) 230V extension cord so you can weld just about anywhere.

• Two stick modes, SOFT and CRISP, provide the right arc characteristics for different types of electrodes.
• Fan-As-Needed™ (F.A.N.™) reduces noise and dust inside the machine.
• Auto-Adaptive Arc Force minimizes electrode sticking in the puddle without compromising arc stability or increased spatter.
• Automatic Hot Start boosts the current during starting to make striking an arc easier.
• Touch Start TIG® mode - it’s like getting a TIG welder for free!
