DC 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.

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 350 has a 120 V auxiliary power receptacle for the cooling system or small tools.

Auto-Line Power Management Technology

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 power.

Stick Features (DC)

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.

Program memory

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

Meter Calibration

Allows meters to be calibrated for certification.
