Optional MIGRunner™ Package Now Includes A Free Bernard Q-Gun & Centerfire Consumables.

Inverter arc control technology provides greater puddle control for superior 6010 Stick electrode performance.

Process selector switch reduces the number of control setup combinations without reducing any features.

Large, dual digital meters are easy to view and presettable to ease setting weld output.

Pulsed MIG capabilities with optional Optima™ control reduces spatter and distortion, allows better out-of-position puddle control, and provides potential reduction of fume particle emmision.

Lightweight, aerospace-grade aluminum case offers protection with the benefit of reduced weight.

Optional - 115 VAC auxiliary power provides 10 amps of circuit-breaker-protected power for water circulators, etc.

Auto-Link® automatically links the power source to the primary input voltage being applied (230V or 460V) or (460V or 575V), without the need for manually linking primary voltage terminals.

Fan-On-Demand™ operates only when needed reducing noise, power consumption, and the amount of airborne contaminants pulled through the machine.

Lift-Arc™ TIG allows DC/TIG starting without the use of high-frequency. Starts the arc without contaminating the weld with tungsten.

Wind Tunnel Technology™
Internal air flow that protects electrical components and PC boards from dirt, dust, debris... greatly improving reliability.

LVC™ Line Voltage Compensation
keeps output of the power source constant regardless of fluctuation in input power ± 10%.

Adaptive Hot Start™ for Stick automatically increases output amperage at the start of a weld should the start require it and prevents the electrode from sticking and creating an inclusion.

Drop-Down Panel
Easy-to-use controls are "under the cover" of the XMT 304 CC/CV.

Compatible with the Wireless Remote Hand Control. Improve productivity, eliminate clutter and cord tangles in the work area. Eliminate cord failure and associated downtime/repair costs and extend the operator's welding range without adding cord extensions.
