Lincoln Electric Invertec V155-S Stick Welder

The V155-S accepts both 120V and 230V input with auto-reconnect operation. Two separate power cords disconnect from the rear panel without tools. It also runs from a portable generator or a 200 ft 230V extension cord for remote job site flexibility.

The V155-S weighs 15 lbs (6.8 kg) making it one of the lightest professional stick welders available. It includes a fully adjustable shoulder strap for carrying to elevated or confined work areas. Despite the compact size it delivers full professional arc performance.

Yes. The built-in Touch Start TIG mode provides DC TIG capability at no extra cost. Touch Start uses contact initiation instead of high frequency so no additional equipment is needed. It handles basic TIG work on steel and stainless steel.

Soft mode delivers a smoother quieter arc suited for 7018 and other low-hydrogen electrodes. Crisp mode provides a more aggressive dig arc for E6010 and E6011 cellulose electrodes that need deeper penetration. Switching between modes takes one button press.

Yes. Auto-Adaptive Arc Force adjusts dig current automatically to prevent the electrode from freezing in the puddle without increasing spatter. If the electrode does stick, Stick-Stuck detection senses it and shuts off welding output so you can safely remove the rod.
