Features

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.
 

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
 

High Efficiency

Three-Phase, rotating-field auxiliary power unit requires less fuel and horsepower to operate.
 

Remote Amperage Control

Provided through 14-pin receptacle on front of the machine.  This permits use of standard and wireless remote amperage control devices.
 

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.
 

Vandalism Lockout Kit

Lockable hinged steel panel protects front control panels and ignition switch.
