325 EFI Kohler Engine Welder/Generator

Miller's Trailblazer 325, in its EFI Kohler configuration, pairs stick, MIG, flux-cored, and TIG welding with an independent generator power system, built for heavy industrial, career-welder-level work rather than occasional hobby use.

What it's for

Auto-Speed technology is standard on this unit, automatically lowering engine speed when less total power is needed and ramping it back up as demand increases, whether that shift comes from changing weld processes or drawing more generator power. Maximum amperage output is rated at 325 amps on single-phase DC, with a 100 percent duty cycle at 325 amps.

What to check before buying

At 460 pounds, plan your mounting and lifting setup around this unit's weight, and note it is built for heavy industrial applications rather than light or home use. The engine and generator packaging on this model is positioned toward the front of the chassis to reduce sound level and footprint, which this maker states improves jobsite communication and leaves more room for other equipment on a truck or trailer. It runs on single-phase DC power, so confirm that matches your shop or jobsite setup before ordering.

Condition and coverage

Sold new rather than used or refurbished, this model carries the Prop 65 label that California law requires on many welding machines, and the manufacturer backs it with a 3-year warranty. Its process coverage spans stick, MIG, flux-cored, and TIG, so confirm that matches the work you have planned.
