Multiprocess Capabilities
MIG, flux-cored, DC stick and DC TIG processes, allowing you ultimate versatility.
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).
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.
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.
Cooling system operates only when needed, reducing noise, energy use and the amount of contaminants pulled through machine.
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.
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.
