400 Pro Kubota Welder/Generator

This 400-amp DC welder/generator runs on a Kubota diesel rather than the Mitsubishi engine used elsewhere in this family, and at 950 pounds it is also the lightest of the 400-amp Big Blue machines in this batch. It is rated for heavy industrial, single-phase use with a 100 percent duty cycle across its full output.

What it is set up to do

Output covers DC stick and DC TIG from 20 to 400 amps, with FCAW and MIG running 14 to 40 volts, so the same machine handles structural stick work and thinner-material MIG or flux-cored passes without a second power source. Generator capacity peaks at 12,000W, with 10,000W continuous, enough to run auxiliary tools alongside the arc.
