The Big Blue 350 PipePro System is a fully integrated pipeline welding system designed to produce steady and reliable arc characteristics in Stick welding, while providing enhanced MIG and Flux Cored welding performance for working with high-strength steels. Components include the Big Blue 350 PipePro diesel engine-driven welder/AC generator; Wireless Remote Hand Control; SuitCase X-TREME 8 HD voltage-sensing, heavy-duty wire feeder; Hobart Brothers' Fabshield 79T8 self-shielded, flux-cored tubular wire; and Bernard's PipePro Dura-Flux.
Miller Electric, Hobart Brothers and Bernard introduce the Big Blue 350 PipePro System, a fully integrated pipeline welding system designed with input from Pipeliners Local Union 798 to outfit pipeline welders with a seamless, rugged solution built to work in the demanding world of pipeline welding.
“With the help of Local Union 798, we’ve built a system that sets a new standard for arc quality and consistency, gives pipeliners the flexibility to transition to Flux Cored welding for high-strength steels, and substantially reduces operating costs in terms of fuel use,” says Roger Hobrock, director, North American pipelines, Miller Electric. Co. “The true end-to-end design of this system means that each component is optimized to work with the next, which will allow pipeline welders to excel the moment they put this system to work.”
The system is designed to produce steady and reliable arc characteristics in Stick welding, while providing enhanced MIG and Flux Cored welding performance for working with high-strength steels. Components of the system include:
Miller’s Big Blue 350 PipePro diesel engine-driven welder/AC generator that provides 20 to 400 amps for both DC Stick (325 amps at 100 percent duty cycle) and DC TIG welding, 14 to 40 volts for MIG and Flux Cored welding (350 amps at 100-percent duty cycle) and 12,000 watt peak/10,000 watts continuous auxiliary generator power for running tools on site. The machine meets all Tier 4i requirements, lowers RPM to 1,850 (compared to 3,600 RPM) and reduces noise and lowers fuel use by as much as 50 percent compared to other units.
Hobart Brothers Fabshield 79T8, a self-shielded, flux-cored tubular wire (E71T8-Ni1 J H8) that requires no shielding gas, features a fast-freezing slag that is easy to remove, performs well in all positions and is ideal for multi-pass welding on deep groove pipe weld butt joints. This wire is optimized within the system for welding on high-strength steel grades in demanding applications.
Miller’s Wireless Remote Hand Control, which allows welders to easily change settings at the point of use for added productivity, extends the remote control range to 300 ft., eliminates remote cord failures, eliminates clutter for improved safety, and improves weld quality with precise operator control thanks to its digital displays.
Miller’s SuitCase X-TREM 8 HD, a voltage-sensing, heavy-duty wire feeder that features a high-torque motor for handling a wide variety of wire diameters and has dual schedule capability. Improved motor control allows for enhanced precision and arc control, while the feeder’s polypropylene case protects it from other environmental challenges of pipeline construction.
Bernard’s PipePro Dura-Flux gun, featuring a replaceable liner that simplifies power cable maintenance, along with a dual schedule switch that easily connects to the SuitCase X-TREME HD’s dual schedule feature for wire feed speed adjustment while welding. Its comfortable handle and lightweight, rotatable Hi-Viz neck reduces user fatigue and improves weld puddle visibility. Its internal trigger leads prevent the trigger cord from getting caught on surrounding impediments and an advanced molded handle design protects the dual schedule switch from weld spatter.
