What are the advantages of a multi-process welder?

Multi-process welders for saleVersatility

Whether you run a shop or work out of your truck, a multi-process welder offers tremendous versatility for anyone whose work varies from day to day. The multi-process machines we carry let you easily switch between Stick, MIG, TIG and Flux Core.

Master of All

All the multi-process welders we carry defy the old adage “Jack of all trades, master of none.” These machines from Miller, ESAB, Tweco and Thermal Arc have the respect of serious welders in a wide range of businesses. If they didn’t, we wouldn’t carry them.

Lighter and Smaller

The new breed of multi-process welders have evolved to a much smaller footprint than older ones—by as much as 40 percent. They’re lighter, too, so you won’t feel as though you’re lugging around a boat anchor. And these new multi-process welders are built to withstand the dust and dirt of job sites, as well as extremes of hot and cold. Check out the Big Blue 400 Pro (Kubota) with ArcReach for an easy to use, fuel-efficient multiprocess welder.

Click around and you’ll see some great incentives on select Miller multi-process welders—like rebates up to $200 and a free helmet and gloves.
