Features

Multi-arc Welding
One dependable engine—two independent arcs with up to 400 amps each. Or plug in additional inverters for a true multioperator work platform! Example: Two additional XMTs equals four operators, up to 200 amps each. Premium-quality arcs allow operators to work independently with no arc interaction. Multioperator welding has never been easier or more versatile.
More Power & Increased Efficiency
33 percent increase in rated output equals 800 amps of weld power and 27,000 watts of generator power. More arcs and better fuel economy equal increased profits for your business. Estimated savings are 34 percent with dual-operator unit versus two single-operator units.
Electronic Engine Display
Simultaneously displays fuel level, engine hours, coolant temperature, oil pressure, battery volts, and engine RPM. Also tracks oil change intervals and displays engine diagnostics for quick and easy servicing.
Heavy-Duty Low-Speed Deutz TD2.9 L4 T4F Industrial Diesel Engine
The cleanest, greenest diesel power available. Utilizes Diesel Oxidation Catalyst (DOC) technology to keep the air clean with NO exhaust aftertreatment maintenance.
Air Compressor - Ingersoll Rand
Ultra-reliable industrial rotary screw air compressor. 30,000-hour life expectancy. Independent on/off control for applications not requiring compressed air — allows greater fuel savings and longer compressor service intervals.
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.
Low OCV Stick (VRD)
Reduces the open-circuit voltage to 15 volts when the welding power source is not in use, increasing operator safety without compromising arc starts. Remote Oil Drain Prevents spills and makes servicing engine and compressor oil easy.
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) Detects if a remote control is plugged into a 14-pin receptacle and eliminates confusion of a remote/panel switch.
Other Standard Features
Digital preset weld meters, automatic idle, vandalism lockout kit (protects control panel and receptacles), and lockout/tagout battery disconnect switch.

Welding Technology Makes Impact on Petro-China WEST-EAST III Pipeline Project
With the drive to construct more efficient oil and gas pipelines in increasingly remote areas, more owners are turning to high-strength steel to meet the demand. Materials like API 5L Grade X80 steel are a common choice. In addition to providing increased strength and pressure tolerances, which allow more materials to pass through, high-strength pipe also offers the ability to work with thinner wall thickness (as little as 18 millimeters). This wall thickness decreases the weight of the pipe and offers considerable savings in terms of transportation cost and labor. Specifically, it minimizes fuel usage and cost for hauls to the jobsite, and also reduces the amount of welding to complete a weld joint.
Maximize Efficiency and Space with Dual-Operator Engine-Driven Welder-Generator
It's increasingly important for companies to complete jobs on schedule and on budget, and fuel and material costs — along with increasing governmental regulations — all play a part in that.
