Miller Electric has launched the Big Blue 350 Pipepro diesel engine-driven welder/AC generator, which has been purpose-built for transmission pipeline welding. The Big Blue 350 Pipepro provides 20-400A for both DC stick and DC TIG welding, 14-40V for MIG and flux-cored welding and 12,000W peak/10,000 continuous auxiliary generator power for running tools on site. Built for the harsh elements encountered in pipeline welding, the machine is also designed for structural steel, construction, fabrication and MRO applications. The Big Blue 350 Pipepro features infinite arc control that allows arc characteristics to be tailored to specific applications in stick, MIG and flux-cored welding. Its 24.4 HP Mitsubishi engine lowers rev/min to 1850 and reduces noise and lowers fuel use by as much as 50% compared with other units. The machine is available in an optional stainless steel package to withstand corrosive elements in harsh environments, and all models come standard with a Line-X-coated top cover for added durability and reliability. It is smaller than previous models (56in depth) to optimise truck space. The machine meets all Tier 4i requirements for 2013 and is designed to operate for more than 10,000hrs before the first basic overhaul.
