325 Kubota Diesel Welder/Generator

This engine-driven welder/generator is built around a 25 HP Kubota diesel and a Miller-built power section rated for 325 amps, with 12,000W of peak generator output and 10,500W continuous. It covers stick, MIG, flux-cored, DC TIG, and air carbon arc cutting and gouging from a single trailer-mounted unit, which suits shops that need both an arc and site power in one trip.

How the controls behave

A built-in speed control tracks the weld load and steps the engine through four preset speeds instead of running flat-out the whole shift, which helps on long days where the load changes often. Two items are factory options rather than standard equipment: a 2,400-watt, 120-volt inverter output for sensitive gear at idle, and feeder-side remote control of the power source without running a control cord back to the machine.

Numbers worth checking before you order

• DC stick output spans 30 to 325 amps, MIG runs 10 to 35 volts, and DC TIG covers 10 to 325 amps
• Sound measures 75 dB at a 150-amp load, climbing to 81.5 dB at the full 325-amp load
• The Kubota D902 diesel is rated 24.8 horsepower at 3,600 RPM, fed from a 12-gallon tank
• Footprint is 28 by 20 by 45.4 inches, and shipping weight is 620 pounds

This unit ships new and carries a 2-year manufacturer's warranty.

Does the generator run while I weld? Yes, the 10,500W continuous rating is independent of the welding arc.

Will it fit a standard utility trailer? Check the 28 by 20 by 45.4 inch footprint and 620-pound weight against your trailer and tie-down points first.
