What's Included

Electronic Engine Display
Electronic engine display simultaneously displays fuel level, engine hours, coolant temperature, oil pressure, battery volts, and engine RPMs. Also tracks oil change intervals and displays engine diagnostics for quick and easy servicing.
Deutz D2.9 L4 Tier 4 Final Compliant Diesel Engine
The cleanest/greenest power available. Utilizes Diesel Oxidation Catalyst (DOC) technology to keep the air clean with NO exhaust aftertreatment maintenance.
Infinite Arc Control
Infinite arc control allows the arc characteristics to be changed for specific applications in Stick, MIG and FCAW.
Thermal Overload Protection
Prevents machine damage if the duty cycle is exceeded or airflow is blocked.
Auto Remote Sense™ (ARS)
ARS detects if a remote control is plugged into the 14-pin receptacle and eliminates confusion of a remote/panel switch.
Low OCV Stick (VRD)
The Low OCV stick welding function is a simple design that reduces the open-circuit voltage to 15 volts when the welding power source is not in use without compromising arc starts.
The Vault
The Vault allows for the ultimate control board reliability in CC/CV models. Hardened solid-state control technology, housed in a sealed vault. The vault's sealed connections are made through watertight plugs that make these components impenetrable to dust and moisture.
Other Standard Features
Remote oil drain to prevent spills and make servicing easy, digital preset weld meters, automatic idle, and 120V block heater for cold environments.
