Details & Inspection Notes

The Miller Maxstar 400 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

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.
