MILLER MAXSTAR 400 DC TIG WELDER

The MILLER

MAXSTAR 400 DC TIG WELDER

is a powerful, compact power source capable of welding up to

5/8 inch

material. Its high-speed pulse control provides maximum productivity and weld quality while conserving energy compared to traditional welding machines.

DC TIG Features



Blue Lightning – High-Frequency Arc Starter


For more consistent non-contact starts and greater reliability compared to traditional HF arc starters.

120 V Auxiliary Power


The Maxstar 400 has a 120 V auxiliary power receptacle for the cooling system or small tools.

Auto-Line Power Management Technology


Allows for any input voltage hookup (208 – 575 V) with no manual linking, providing convenience in any job setting. Ideal solution for dirty or unreliable

Other TIG Features


• Exceptionally smooth and precise arc for welding exotic materials.

• High-speed DC TIG pulse controls; Pulse frequency capable of pulsing 5000 pulses per second. Pulsing adds arc stability, reduces heat input and warpage and can increase travel speeds. Other parameters include peak amperage, peak time and background amperage.

Stick Features (DC)



Program memory


Program memory features 9 independent program memories that maintain/save your parameters.

Meter Calibration


Allows meters to be calibrated for certification.

Other Stick Features


• Tailored arc control (DIG) allows the arc characteristics to be changed for specific applications and electrodes. Smooth running 7018 or stiffer, more penetrating 6010.

• Hot Start adaptive control provides positive arc starts without sticking.

Cart with the following features:


• Single cylinder rack
