Features

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.
Heavy-Duty Low-Speed Mitsubishi S4L2 Industrial Diesel Engine
Used in industrial applications around the world, the S4L2 is designed to run 10,000 hours before major overhaul. Backed by worldwide support and service.
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.
Superior Stick Arc Performance
Even on the difficult-to-run electrodes like E6010
Remote Amperage Control
Provided through 14-pin receptacle on front of the machine.  This permits use of standard and wireless remote amperage control devices.
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.
High Efficiency
Three-Phase, rotating-field generator requires less fuel and horsepower to operate.
Vandalism Lockout Kit
Lockable hinged steel panel protects front control panels and ignition switch.
