Quiet Operation
At just 72.2 decibels at 23 feet (7 m), it’s quieter than most single-operator models, improving jobsite communication and safety. Learn More
Adaptive Hot Start™ For Stick Arc Starts
Automatically increases the output of a weld should the start require it. Prevents the electrode from sticking and creating an inclusion.
High Efficiency
Three-Phase, rotating-field auxiliary power unit requires less fuel and horsepower to operate. Learn More
Remote Amperage Control
Provided through 14-pin receptacle on front of the machine. This permits use of standard and wireless remote amperage control devices. Learn More
Multi-function Fuel Gauge
Displays fuel level and engine hours, and can be customized to set oil change interval reminders. In the case of high coolant temperature, low oil pressure, or low fuel level, the engine will shut down to prevent damage, or make restarting easier.
