Just got this news from Miller Electric about their new diesel engine-driven welder/AC generator (see below).  This thing is its own power plant!

And don’t forget, offers TIG torches and replacement parts, MIG guns and replacement parts, stick holders and leads, and plasma arc cutting torches and replacement parts.

Miller PipePro

Miller Electric Mfg. Co. today introduces the Big Blue® 350 PipePro diesel engine-driven welder/AC generator. The Big Blue 350 PipePro, purpose-built for transmission pipeline welding, 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. 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. Overall arc quality is improved, Stick flaring issues are eliminated, and MIG/Flux Cored controls have been enhanced and simplified to optimize the machine for wire welding. This is critical as many transmission pipelines are transitioning to high-strength steels where Flux Cored welding provides optimal performance.

Miller’s “Vault”—two halves of aluminum casing sealed together—protect the machine’s circuit board from dirt, moisture and heat to ensure consistent operation, including unwavering arc consistency and generator power. Its 24.4 HP Mitsubishi engine 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.

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’s smaller than previous models (56-in. depth) to optimize truck space. The machine meets all Tier 4i requirements for 2013 and is designed to operate for more than 10,000 hours before the first basic overhaul.

Industry Quote
“We’ve worked extensively with Miller on the development of this. It’s a strong machine that has good arc characteristics. You get the exact same amperage out of it every time you use it as opposed to a DC generator that varies with temperature. They can count on it being the same weld characteristics every time they strike an arc.”
—Farron Hollabaugh, director of training, Pipeline Local Union 798

Additional Information
Built to Last
The Big Blue 350 PipePro’s rated outputs are tested and verified at 104 degrees Fahrenheit. Miller’s industrial engine drives are subjected to airborne dust and sand, humidity, corrosion, temperature extremes, shaking, vibration and continuous use as part of the rigorous testing process to ensure optimal performance in all conditions. Additional features include an engine temperature gauge, digital preset weld meters, output contactor control, automatic idle and Miller’s Auto Remote Sense (ARS) that detects if a remote control is plugged into the 14-pin receptacle and eliminates confusion of a remote/panel switch.
