Trailblazer 330 Engine-Driven Welders

Coming in at 86 lb. lighter, 13% smaller than previous models, and providing lower fuel costs and reduced noise, Trailblazer 330 machines deliver improved weld process and parameter control and output, yielding higher weld quality, more productivity, and data visibility.

Trailblazer 330 engine-driven welders let operators dial in weld settings thanks to a digital user interface and controls. The machines offer up to 330 A at 31V and 100% duty cycle, so operations can get high deposition rates by running bigger-diameter, flux-cored wire and gouging thicker materials. Users also get more control with pulsed TIG, while updated Dynamic DIG technology provides smooth, consistent stick arcs tailored to match applications, materials, fit-up, and welder technique. Inductance adjustments deliver precise control for flux-cored wire applications.

Auto-Speed technology automatically adjusts engine speed to match any load, so the engine never runs faster than necessary. Excel power delivers auxiliary AC power at fuel-saving, quieter idle speed, while wireless interface control (WIC) allows complete front panel operation from anywhere on the jobsite.

Trailblazer 330 welders also include:

  • ArcReach Technology: Change parameters at the weld joint with an ArcReach feeder.
  • Cable Length Compensation (CLC) and Weld Lead Calibration (WLC) Technology: Adjust voltage based on weld cable length, making parameter setup faster and ensuring voltage is correct—even hundreds of feet away from the machine.
  • Auto-Set Technology: Preset controls for speed, convenience, and confidence for welders of all skill levels.
  • Battery Charge/Crank Assist: Charge batteries (12 or 24V) without using an additional charger or crank assist.  
  • Polarity Reversing: Switch between stick, flux-cored or gouging with no need for cable swaps.

In addition, the 330 delivers more data visibility, making it easier for operations to track maintenance and bid jobs competitively. The user interface shows maintenance screens and provides alerts for upcoming tasks, including oil, filter, and generator brush changes. In addition, the interface has productivity screens that make it easy to see the hours spent on a specific job and also connect to telematics systems, improving fleet visibility.

Features:

  • Digital user interface simplifies access to advanced weld settings for better results.
  • Better stick arcs with Dynamic DIG technology; has pulsed TIG for more control.
  • Auto-Set technology delivers the speed, convenience, and confidence of preset controls, making weld parameter setup fast, easy, and accurate.
  • Arcs start easily and produce less spatter.
  • Delivers 330 A at 31V, at 100% duty cycle, for high deposition rates and gouging.
  • Electrical loads on the generator have zero arc interaction, helping to ensure higher weld quality.
  • Advanced Auto-Speed technology automatically adjusts engine speed to weld load, ensuring the engine never runs faster than necessary.
  • Excel power (optional) delivers auxiliary AC power at fuel-saving, quieter idle speed.
  • Cable Length Compensation (CLC) and Weld Lead Compensation (WLC) ensure that the right voltage is delivered at the weld joint, even with long weld cables.
  • Wireless Interface Control (optional) puts full control of the machine in the palm of a welder’s hand, anywhere on the jobsite.
  • Polarity-reversing technology (optional) makes switching between processes fast and easy without cable swaps.
  • ArcReach technology lets welders change parameters and switch polarity at the weld joint.
  • Available Battery Charge/Crank Assist: No need for a standalone battery charger.
  • 240V receptacle: Easily connect plasma and other tools without an adapter.
  • Maintenance screens help you plan downtime for routine service.
  • Productivity screens show hours spent on each job.
  • Easy connection to telematics systems improves fleet visibility.
