Miller Maxstar® 400 Complete with Foot Control 951692
The Miller Maxstar® 400 Complete W375 is a 400 amp DC TIG welder package that comes complete with remote amperage foot control, TIG torch with accessories, water cooler with 4 gallons of coolant, shielding gas regulator with hose and running gear with cylinder rack. It features pulsed TIG welding, and operates on either single phase or three phase input power. Miller's Auto-Line™ technology allows connection to any input voltage in the world while using half the power of a non-inverter welding machine.
The Maxstar 400 offers design improvements over previous Maxstar 350 models. New design benefits include: increased resistance to adverse environmental conditions, memory card port for easy software updates or expansion. The Cooler-On-Demand™ feature operates the Coolmate™ TIG torch cooling system only when needed, saving power and unnecessary wear and tear on the water cooler. The Pro-Set™ feature automatically sets welding parameters for you, eliminating guesswork. The Maxstar 400 can also be run in manual mode, allowing you to customize your own welding parameters.
