Miller Maxstar® 400 TIG Welder 907716
The Miller Maxstar® 400 is a 400 amp DC TIG welder that 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 auxiliary TIG torch cooling system only when needed, saving power and unnecessary wear and tear on the optional 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.
Direct replacement for the Miller Maxstar® 350.

Auto-Line™ allows for any input voltage hookup
(208 Volt to 575 Volt) with no manual linking,
providing convenience in any job setting.
Ideal solution for dirty or unreliable power.
Meter calibration allows digital meters to
be calibrated for certification.
Cooler Power Supply (CPS)
is an integrated 120-volt
dedicated-use receptacle for
the Coolmate™ 3.5.
Wind Tunnel Technology™
protects internal electrical
components from airborne
contaminants, extending the
Fan-On-Demand™ power source
cooling system operates only when
needed, reducing noise, energy use
and the amount of contaminants
pulled though the machine.
Lift-Arc™ provides AC or DC
arc initiation without the use of
Blue Lightning™ high-frequency (HF)
arc starter for non-contact arc initiation.
Provides more consistent arc starts
and greater reliability compared to
traditional HF arc starters.
Program memory features nine
independent program memories
that maintain/save your parameters.
Auto-postflow adjusts the length of
postflow time based on the amperage
setting, shielding your tungsten
and eliminating the need to set the
