Update & Expand

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

Pro Set

Eliminates the guesswork when setting the 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 display.

Sleep Timer

Conserves electricity. This programmable feature will power down the machine if it sits idle for a specified time.

Blue Lighting™

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.

Auto-line Power Management Technology™

Allows for any input voltage connection (120 – 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.

DC TIG Features

  • Exceptionally smooth and precise arc.

AC TIG Features

  • Balance control provides adjustable oxide removal which is essential for creating the highest quality aluminium welds. DX models provide extended ranges.
  • Frequency controls the width of the arc cone and can improve directional control of the arc.

AC/DC Stick Features

  • Hot Start™ adaptive control provides positive arc starts without sticking.
  • AC frequency control adds stability for smoother welds when AC Stick welding.
  • 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.
