Intuitive Interface LCD Display
Ensure proper machine setup and parameter selection with informative on-screen explanations and dynamic images.
Program Memory
Allows easy naming, saving and recalling of favorite weld settings.
Pro-Set Feature (professional settings)
This feature eliminates the guesswork when setting weld parameters. Use Pro-Set when you want the speed, convenience and confidence of pre-set controls. Simply select the feature and adjust until Pro-Set appears on the display. The Pro-Set feature is available for Balance, Frequency, Pulse and DIG parameters.
Locks and Limits
Provides control of the weld parameter ranges minimizing deviations from the welding procedure specifications (WPS).
USB Port
Provides the ability to easily update software, back-up settings and transfer saved weld programs from one unit to the next.
Auto-Line™ Technology
For portability and reliability this inverter power supply allows for any single-phase input voltage hookup (208–600 V) with no manual linking, providing convenience in any job setting. Ideal solution for dirty or unreliable power.
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. Hot Start™ adaptive control provides positive arc starts without sticking.   Learn More
CV output of the power source gives this unit MIG process capabilities when paired with an ArcReach® 8 or 12 (or other voltage-sensing feeder).
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.
Feature operates the auxiliary cooling system only when needed, reducing noise, energy use, and airborne contaminants pulled through the cooler.   Learn More
Cooling system operates only when needed, reducing noise, energy use and the amount of contaminants pulled through machine.
