APPLETON, Wis., March 17, 2009--Miller Electric Mfg. Co. introduces the Trailblazer® 302 Air Pak(TM), the industry's first gasoline engine-driven welder, generator and air compressor that meets job site reliability standards. 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 Accu-Rated(TM) generator power and 26 CFM at 100-percent duty cycle.

The Trailblazer 302 Air Pak's rotary screw air compressor delivers 70 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. It substantially improves air carbon arc cutting and gouging, and is capable of working with ¼-in. carbons (rated: 3/16-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 5/8-in.

The Trailblazer 302 Air Pak's 30 HP Kohler gas engine, weighs 771 lbs. and measures 59-1/2 in. long (just 14 in. longer than a Trailblazer 302) x 20 in. wide x 34-1/4 in. high. It occupies up to 50 percent less truck pace and up to 25 percent less axle weight compared to using a separate engine-driven air compressor. It also lowers fuel use and simplifies equipment management.

Customer Quotes

"The Trailblazer 302 Air Pak has the same height and width as a regular Trailblazer, but it's 14 inches longer. It fits in the back of any truck. With a compressor inside the welder, we have one less piece of equipment to pack and one less engine to fuel and maintain. It creates more room for gang boxes and frees up weight for other tools."

-Dan Chapman, owner, CMW Welding, Spring Grove, Ill.

Additional News Release Information

More Generator Power

The Trailblazer 302 Air Pak is a true 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 volts (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. Its 13,000 watts of Accu-Rated(TM) generator power (11,000 watts continuous) gives contractors the most generator power of any gas welder generator. Running Miller 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 powerful multi-arc system to increase productivity while lowering fuel use and cost-per-arc ownership.
