Details & Inspection Notes

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.

Before you order

  • Idle sound is rated at 66 dB, rising to 71.6 dB under weld load
  • Overall dimensions are 32 by 26.25 by 56 inches
  • It is rated for Career Welder-level use and ships with a 3-year manufacturer's warranty
  • This is a new unit; confirm your feeder setup matches the standard 14-pin receptacle before ordering

Panel controls run through the standard set for this engine family: metering, hot start, idle control, block heater, and a corrosion-resistant finish.

How heavy is this unit to move? 950 pounds, the lightest of the Kubota- and Mitsubishi-powered 400-amp machines in this range.

Does it need three-phase power? No, it is a single-phase machine per the listed specification.

Welding Equipment Setup & Pre-Operation Checklist

  • Verify workshop mains voltage, circuit breaker rating, and phase match the welding machine specifications.
  • Inspect ground clamp cable, torch lead, and work cables for tight, clean, low-resistance connections.
  • Secure shielding gas cylinders upright with safety chains; inspect regulator and hose connections for gas leaks.
  • Confirm correct wire diameter, drive roll groove profile, and contact tip size match the spool installed.
