Miller Big Blue™ 500 Pro (Kubota) #907736

The Big Blue™ 500 Pro isn’t just one of the most tremendous Diesel Engine-Driven Welder/AC Generators from Miller®, it’s also the cleanest and greenest power available. The backbone to this green, clean, multi-purpose welding machine, is in the heavy-duty T4i Kubota diesel engine. This generator packs an incredible 27,000 peak watts of power on 3-phase or 15,000 watts on single-phase, all while keeping the air clean from after treatment maintenance exhaust, due to the Miller® diesel oxidation catalyst (CDC) technology. You’ll need more metal to craft after welding with this machine.

Electronic Engine Display (Kubota USA Models Only)
