Upgradeable and expandable

Front panel memory card data port provides the ability to easily upgrade software and expand product features.

Pro-Set™

Eliminates the guesswork when setting weld parameters. Use Pro-Set when you want the speed, convenience and confidence of preset controls. Simply select the feature and adjust until Pro-Set appears on the display.

Sleep timer

Conserves electricity by powering down the machine if it sits idle for a specific time.

Auto-Line™ power management technology

Allows for any input voltage hookup (208–575 V) with no manual linking.

Cooler Power Supply (CPS)

An integrated 120-volt dedicated-use receptacle to power the Coolmate™ 1.3. The power switch on the Maxstar also activates the receptacle to help prevent torch failure.

Cooler-On-Demand™

Feature operates the auxiliary cooling system only when needed, reducing noise, energy use, and airborne contaminants pulled through the cooler.

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.

Wind Tunnel Technology™

Protects internal electrical components from airborne contaminates, extending the product life.

Meter calibration

Allows digital meters to be calibrated for certification.

Fan-On-Demand™

Power source cooling system operates only when needed, reducing noise, energy use and the amount of contaminants pulled though the machine.

DC TIG Features

Exceptionally smooth and precise arc for welding exotic materials.
Pulse. Pulsing can increase puddle agitation, arc stability and travel speeds while reducing heat input and distortion.

DC Stick Features

DIG control allows the arc charac teristics to be changed for specific applications and electrodes. Lower the DIG setting for smooth running electrodes like E7018 and increase the DIG setting for stiffer, more penetrating electrodes like E6010.
Hot Start™ adaptive control provides positive arc starts without sticking.
Stick-Stuck detects if the electrode is stuck to the part and turns the welding output off to safely and easily remove the electrode. Menu selectable.
