500 PRO KUBOTA WELDER/GENERATOR
The Miller big blue 500 PRO KUBOTA WELDER/GENERATOR (907736) comes with a Kubota diesel engine and delivers 500 amps of DC welding output. The generator can produce 27,000 peak watts of power when using 3-phase or 15,000 watts on a single phase.
The Kubota heavy-duty T4i diesel engines are the cleanest, greenest diesel power available. These models utilize diesel oxidation catalyst (CDC) technology to keep the air clean with NO exhaust after-treatment maintenance.
The electronic engine display simultaneously displays fuel level, engine hours, coolant temperature, oil pressure, battery volts and engine RPM. It also tracks oil change intervals and displays engine diagnostics for quick and easy servicing.
