Update & Expand

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


Eliminates the guess work 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. This programmable feature will power down the machine if it sits idle for a specified time.

VRD Functionality

Comes with Voltage Reduction Device (VRD), compliant with AS1672.2 2007 Category C Environment. Please note: VRD can be disabled in Advanced Tech Menu by pressing a combination of unmarked buttons.

Auto-Line Power Management Technology

Allows for any input voltage hookup (210 – 480 V) with no manual linking, providing convenience in any job setting. Ideal solution for dirty or unreliable power. Will run on single phase and 3 phase power. Tolerant to lower generator output.

Cooler Power Supply (CPS)

An integrated 120 volt dedicated-use receptacle for the Coolmate™ 1.3.


This 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.

Meter Calibration

Allows digital meters to be calibrated for certification.

Wind Tunnel Technology™

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


Variable speed fan adjusts to match cooling requirements - reducing noise, energy use and the amount of contaminants pulled through the machine.
