Miller Releases the New Bobcat™ 265 Air Pak™ and Trailblazer® 330 Air Pak™ Engine-Driven Welders

Integrated air compressor can save field operators time, money and space on the jobsite 

Miller Electric Mfg. LLC, a leading worldwide manufacturer of Miller®brand arc welding equipment, has announced the release of the Bobcat 265 Air Pak and Trailblazer 330 Air Pak. In addition to the Air Pak options, the Bobcat 265 is available in gas and LP models, while the Trailblazer 330 comes in gas and diesel.

Both the new Bobcat 265 Air Pak and Trailblazer 330 Air Pak offer all the legendary benefits with the added advantage of an integrated industrial rotary-screw air compressor that eliminates the need for a separate compressor. These powerful all-in-one machines are lighter and smaller than previous models, offering multiprocess weld quality, auxiliary power, battery charge/crank assist and, now, an air compressor — delivering all-in-one capabilities for maintenance, repair operations and field fabrication.

“The new Bobcat and Trailblazer Air Pak engine-driven welders eliminate the need to have a separate air compressor, lightening up operators’ payload and saving them space,” says Brian Bellile, product manager, Miller. “Both machines are ideal for work truck and field fabricators. Regardless of which machine is best for your operation, these machines are all-in-one solutions for professionals across industries, preparing them for any job and repair on the jobsite.”

Both Air Pak machines allow operators to run air impact wrenches and give 100% deliverable air. The compressor produces 30 cfm of air at 100% duty cycle and delivers 80-160 psi of air with an optional storage tank for consistent airflow performance. Other benefits of the Bobcat 265 Air Pak and Trailblazer 330 Air Pak include:

  • Auto-Set™ technology makes weld parameter setup quick, easy and precise for all operators.
  • Standard battery charge/crank assist eliminates the need to carry a stand-alone battery charger on trucks.
  • An advanced, independent welder and generator power system ensures no interaction between the welding arc and jobsite tools. Weld quality is increased and jobsite tools can run without interruption.
  • Multiprocess welder allows common welding processes, helping operators complete quality welds every time.
  • A direct spool gun connection makes it quick and easy to connect spool guns for welding aluminum.
  • Front panel predictive maintenance displays alert you when your equipment needs to be serviced, and access doors and toolless panels make servicing the machine accessible and simple.
  • Easily connect 240-volt tools without the need for an adapter.
  • Digital interface speeds and simplifies machine setup.
  • The machines are smaller and lighter than previous models for easier mobility and more truck space.

Beyond the shared features of the two machines, each has unique benefits. The Bobcat 265 Air Pak is lightweight at only 570 pounds with a small footprint to fit easily on a work truck.

MillerThe Trailblazer 330 Air Pak features exclusive benefits and advanced settings designed to further productivity and weld quality. This machine provides up to 330 amps at 30.5 volts and 100% duty cycle to allow high deposition rates by running bigger-diameter flux-cored wire and gouging thicker materials. Operators also get more control with pulsed TIG, and the updated Dynamic DIG™ technology provides smooth, consistent stick arcs tailored to match applications, materials, fit-up and welder technique. Other benefits exclusive to the Trailblazer 330 engine-driven welder include:

    • Excel™ power provides auxiliary AC power, delivering it at a fuel-saving, quieter idle speed — standard on the Trailblazer 330 Air Pak.
    • Standard ArcReach® technology lets operators change parameters at the weld joint with an ArcReach feeder. This decreases the downtime spent walking to the machine and reduces exposure to slip, trip and fall hazards.
    • Cable Length Compensation (CLC™) ensures that the voltage welding operators set is the voltage they get — even hundreds of feet away from the power source.
    • Advanced Auto-Speed™ technology adjusts engine speed automatically to match any load, so it never runs faster than necessary.
    • For remote current, voltage and contactor control, a receiver plugs directly into the 14-pin receptacle of the machine for up to 300 feet of operating range.
    • Wireless Interface Control (WIC) allows complete front panel operation from anywhere on the jobsite.
    • Select models include standard Polarity Reversing, allowing users to switch between stick, flux-cored or gouging with no need for cable swaps — saving time and improving weld quality by eliminating the risk of welding in the wrong polarity.

The Bobcat 265 Air Pak and Trailblazer 330 Air Pak engine-driven welders are legends redefined, now equipped with industrial rotary-screw air compressors to tackle maintenance and repair on any truck or jobsite. By eliminating the need for a separate air compressor, these all-in-one solutions can save operators and operations time, money and space. For more information, visit
