Kohler Welder/Generator with Gfci

This Miller Bobcat, a three-phase welder/generator built around a Kohler engine with GFCI protection, pairs a 210A stick, MIG, flux-cored, and TIG welder with a generator sized to run single- or three-phase loads, which makes it suited to farm and ranch settings that need backup or field power as much as a welding arc.

Who it suits

Miller designed this generation of Bobcat around quieter running: the engine sits rotated toward the front for more efficient airflow, which cuts sound level and lets crews start earlier or work later near houses and job sites without complaint. Daily maintenance is handled from the front panel, with toolless panels, a single-side fuel fill and oil drain, and maintenance displays that flag service needs before they become problems.

Generator power and layout

On the generator side, output is rated at 11,000 watts of usable peak power (12,000 with EFI), sustained for at least 30 seconds, enough for plasma cutting, running Millermatic MIG welders, or starting motors. The ten-degree skewed-rotor design is built to smooth that power rather than deliver spikes, and the reversed airflow layout keeps internals cooler and reduces hot-air recirculation when the unit is parked in a tight spot. The frame is also sized and shaped to take up less space on a truck or trailer than earlier Bobcat generations, with grab bars positioned for safer lifting.

Common questions

What welding processes does it run? Flux-cored, MIG, Stick, and TIG at up to 210A with a 100% duty cycle rating. Does it include GFCI protection? Yes, as the name states. This unit is subject to a California Proposition 65 warning label.
