Multiprocess

Multi-process welders/cutters are unique in design and innovation. LONGEVITY was the leading company to design machines known as all-in-one welders to feature an AC/DC TIG + STICK + PLASMA cutter in one machine called the WELDALL! In addition to the WELDALL series, LONGEVITY has a WELDMAX series that includes DC TIG + STICK + PLASMA and a PROMTS series that features a MIG + TIG + STICK combination welder.

If you are looking to save space or for a machine that can do it all, look at LONGEVITY's multiprocess welders and cutters.
