500 Pro Kubota Welder/Generator

This Kubota diesel welder/generator delivers 500 amps of DC output and is built for crews who need sustained heavy use: duty cycle is rated 100 percent at 400 amps and 500 amps alike, so the arc does not need to be babied on long runs. Three-phase service unlocks 27,000 peak watts of generator capacity; single-phase tops out at 15,000 watts.

Engine and monitoring

The diesel meets Tier 4 emissions requirements using a catalyst-based exhaust treatment that needs no separate maintenance of its own. Its electronic display puts battery voltage, oil pressure, coolant temperature, engine RPM, run hours, and fuel level on one screen, flagging upcoming oil-change intervals and basic fault codes along the way.
