The Lincoln Electric Invertec® V155-S is a testament to the fact that size does not dictate power. Designed for the rigors of industrial maintenance, pipeline support, and mobile fabrication, this machine packs a professional 155-amp output into a chassis weighing less than 15 pounds (6.7 kg). For technicians who move from the workshop to the field, the V155-S offers unmatched versatility with its 120/230V auto-reconnect input power. This feature allows the unit to operate seamlessly on standard household power or high-voltage industrial lines without manual switching, ensuring you are ready to weld wherever the job takes you.
Beyond its physical portability, the V155-S is engineered for arc performance. It features two distinct stick welding modes: "SOFT" and "CRISP." The Soft mode produces a smooth arc with reduced spatter, ideal for running E7018 electrodes on clean steel. The Crisp mode delivers a more digging, penetrating arc, perfect for E6010 or E6011 cellulosic electrodes often used in pipe and root pass applications. This dual-mode capability ensures that professional welders have the right arc characteristics for the specific electrode and base material they are working with.
Reliability in harsh environments is a core component of the Invertec design. The machine utilizes Lincoln's Fan-As-Needed™ (F.A.N.) technology, which operates the cooling fan only when the system's thermal demands require it. This reduces the amount of conductive dust and debris drawn into the machine during idle times, significantly extending component life in grinding-heavy environments. Additionally, the unit is fully generator compatible, making it an excellent choice for remote sites where grid power is unavailable.
The V155-S is not just a stick welder; it also features Touch Start TIG® capability. This allows for DC TIG welding with a lift-arc start technique, avoiding the tungsten contamination associated with scratch starting. Whether you are repairing stainless steel process piping or fabricating mild steel railings, the Invertec V155-S delivers consistent, high-quality results in a rugged, portable package.
