Accu-Rated Generator Power
Self-Calibrating Digital Meters with Maintenance Displays
- Preset and actual weld amperage/voltage for precise setting and monitoring.
- Engine hour meter to track machine usage.
- Oil change countdown indicates how many hours are left before an oil change is due making maintenance tracking easy.
- Front panel fuel gauge is the most convenient location.
- Engine RPM display is convenient for servicing.
Independent Weld and Generator Power
Superior Arc Performance
- Four preset DIG settings (Stick) to make the arc softer or stiffer depending on electrode and operator preference.
- Adaptive Hot Start (Stick) ensures easy arc starts regardless of operator technique.
- Excellent MIG/FCAW arc performance to run smoothly with solid and flux-cored wires.
- Lift Arc TIG with Auto-Crater and Auto-Stop. Lift Arc minimizes/eliminates contamination when starting, Auto Stop prevents arc flare at the arc end and Auto-Crater eliminates the need for a remote control by automatically ramping down amperage at the end of a weld to fill in the crater.
