The Vantage® 400 is one of the most compact 400 amp engine-driven welder/ generators in the construction, pipe or rental fleet market today. It's also one of the most quiet, with the smooth running 4-cylinder Perkins® or Kubota® diesel engine. Use this multi-process welder for arc gouging with up to 5/16” carbons, stick welding with up to 1/4” electrodes and CV wire welding with up to 3/32” wire. You'll value the superior arc performance delivered by Lincoln Chopper Technology. You'll also appreciate VRD™ (Voltage Reduction Device™), which reduces OCV (open circuit voltage) in the CC-Stick weld mode for added safety. This model efficiency generates 19,000 watts (peak) of 3-phase or 12,000 watts of 1-phase AC generator power for your lights, grinders and power tools. And, it's housed in a rugged, low maintenance stainless steel enclosure and loaded with many innovative service features. That all totals up to an excellent value!
