Next-generation, rugged, low-speed diesel welder/generator designed for the transmission pipeline contractor.
Heavy Duty Low-Speed CAT Industrial Diesel Engine
With the reliability you expect from Miller, the CAT C1.5T turbo-charged three-cylinder, liquid-cooled, industrial diesel engine is backed by world-class support and service through the global CAT dealer network.
Line-X Top Cover
Workbench tough top cover provides superior impact, corrosion and abrasion protection.
HD Powder Coat
All painted sheet metal is pretreated with a zinc-rich primer to provide extra protection against rust & corrosion (comparable to stainless steel).
Designed for the Welding Rig
The Big Blue 400 PipePro is the smallest, lightest and most powerful welder in it’s 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.
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.
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.
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.
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.
