Used Lincoln Electric Invertec V350-PRO: Sell or Buy at Auction

Lincoln Electric is the world's largest welding manufacturer, with a comprehensive range of welding machines, wire feeders, and robotic welding systems. Lincoln Electric is the dominant brand in North American welding, making Lincoln equipment highly liquid in the used market with active buyer demand.

The Invertec V350-PRO is one of Lincoln Electric's most widely used multi-process inverter power sources, rated 350 amps at 60 percent duty cycle and 300 amps at a full 100 percent duty cycle, with output that adjusts from a few amps up past 400 for heavy passes. From a single machine it runs Stick, MIG, TIG, flux-cored, and air carbon arc gouging, and it accepts a range of input voltages (208, 230, 460, and 575 volt, three phase), so a crew can move it between processes and job sites without matching it to one supply. Lincoln's Chopper Technology gives the V350-PRO true CC and CV output in one unit, which lets a shop cover structural, pipe, and gouging work that would otherwise take several separate transformer-based welders. That versatility is why structural steel fabricators, shipyards, and pipeline contractors standardize fleets on the model, and why used units are a known quantity in the field before a listing goes live: bidding on a V350-PRO tends to be immediate rather than exploratory. KD Auctions regularly moves these units through its network of 500,000+ industry contacts, where fabrication shops and pipeline crews watch specifically for this model and its wire feeder and running gear pairings.
