Miller Electric Mfg. Co. (www.millerwelds.com) has introduced the Trailblazer 302 Air Pak — a gasoline engine-driven welder, generator and air compressor. The Trailblazer 302 Air Pak is designed to provide construction structural steel and equipment repair professionals with a self-contained power source that welds at up to 350 amps, provides 13,000 watts of Ace-Rated generator power and 26 cam air at 100-percent duty cycle.

The unit's rotary screw air compressor delivers 70-psi to 160-psi of air with no storage tank required. It runs most air impact wrenches at idle and provides 100 percent deliverable air, which allows contractors to work continuously without worrying about air pressure. The company said the unit substantially improves air carbon arc cutting and gouging, and is capable of working with 0.250-in. carbons (rated: 0/1875-in.) for most applications. It also provides more than enough power and air pressure to run Miller's full line of portable Spectrum plasma cutters with a rated cut of 0.625-in.

The Trailblazer 302 Air Pak's 30 hp Kohler gas engine, weighs 771 lb and measures 59.5- in. long (just 14 in. longer than a Trailblazer 302) by 20-in. wide by 34.250 in. high. It occupies up to 50 percent less truck pace and up to 25 percent less axle weight compared with using a separate engine-driven air compressor. It also lowers fuel use and simplifies equipment management.

The unit is a multi-process machine that provides strong stick, MIG, flux cored, AC/DC TIG, and air carbon arc gouging and cutting performance. It provides 25- to 300-amps of dc output for stick, 10- to 300-amps of dc output for TIG, 10- to 225-amps for ac TIG/stick and 13- to 35-v (350 amps) for MIG and flux cored welding.

The Trailblazer 302 Air Pak's two-generator design, one for welding and one for power generation, ensures that the welding arc remains stable when power tools are being used. Miller said its 13,000 watts of Accu-Rated generator power (11,000 watts continuous) gives contractors the most generator power of any gas welder generator. Running the company's welders, such as the Millermatic, Maxstar 200 and Dynasty 200, off of the Trailblazer 302 Air Pak's generator power further transforms this engine drive into a multi-arc system to increase productivity while lowering fuel use and cost-per-arc ownership.
