Miller Big Blue® 400 PipePro® (Mitsubishi) w/ Stainless Steel #907703

The next generation is here. This rugged, low-speed diesel welder/generator was designed for transmission pipeline contractors and gets the job done every time.

Heavy-Duty Low-Speed Mitsubishi S4L2 Industrial Diesel Engine
Used in industrial applications around the world, the S4L2 is designed to run 10,000 hours before major overhaul. Backed by worldwide support and service.
Stainless Steel Enclosure
Standard stainless steel enclosure enhances durability & adds to the look and resale of the machine.
ArcReach® Technology
Exclusive ArcReach technology uses existing weld cables to communicate process adjustment commands back to the welder generator. With an ArcReach system, amperage & voltage are conveniently located at the operator's fingertips - not back at the power source.
All Day Consistency
Unlike traditional DC style generators that have a hard time maintaining a consistent output due to daily fluctuations in ambient temperature, the advanced controls on the PipePro stabilize and keep output right where you set it.
Industrial USB Port
Quickly upload the latest software and download machine log files to retrieve in-depth information such as diagnostics and machine statistics.
Dynamic DIG
Unlike conventional DIG that provides a preset amount of short-clearing current, Miller’s proprietary Dynamic DIG works on a time-based algorithm that automatically adjusts the amount of current required to clear a short. What does this mean? A smoother more consistent arc that can be tailored to match application, material, fit-up, and welder technique.
Line-X® Top Cover
Workbench tough top cover provides superior impact, corrosion and abrasion protection.
Designed for the Welding Rig
The Big Blue 400 PipePro is the smallest, lightest and most powerful welder in its class. This means less wear & tear on the truck chassis, more room and capacity for equipment, and greater visibility out the rear window of the truck.
Wireless Remote Compatible
Eliminate pesky control cords and remote boxes through the use of Miller's wireless hand control (#300430). Easily control welding output up to 300 ft. away from the Big Blue without ever having to make a trip back to the truck. Wireless Antenna Kit recommended (#300749).
Other Standard Features
Output contactor control, automatic idle, thermal overload protection, and 120-volt engine block heater.
