More Jobsite Productivity and Efficiency

AC/DC CC/CV multiprocess equipment means always having the right equipment for the job. This also simplifies logistics and translates into less time locating and moving equipment and more time welding.

Reduced Training Time

Reduced training time by utilizing one piece of equipment, saving labor costs and helping to keep projects on schedule.

More Operator Control

Weld operators can quickly and easily adjust parameters, reducing the risk of operators trying to get by with less than ideal settings. Also, state-of-the-art TIG functions such as pulse, high-frequency starting, and AC (for aluminum) allow for optimization for virtually any material type.

Improved Jobsite Safety

Portable welding equipment allows for easy movement of equipment to point of use. The chances of slip, trip or fall injuries are virtually eliminated because there is no need to travel through multi-story and cluttered jobsites back to the power source since adjustment is point of use.

Increased Uptime

Low power draw can mean additional welding equipment on the same circuit, getting work done faster by reducing the chances of power outages from tripped breakers or blown fuses.


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


CV output of the power source gives this unit MIG process capabilities when paired with an ArcReach® SuitCase® feeder (or other voltage-sensing feeder). The feeder is powered off the arc voltage of the power source and can run both solid and flux-cored wires

AC/DC Stick

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.
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.
