Miller® Trailblazer® 330 Engine Driven Welder 907831

The Miller® Trailblazer® 330 is a 330 amp DC welder and 12,000 watt AC generator that features a Kohler® 23.5 HP gasoline engine.  Weighing in at just 400 pounds, the Trailblazer 330 is over 80 pounds lighter and 13% smaller than previous Miller Trailblazer models.  It is specifically designed to take up less room in your pick up truck or UTV. The Trailblazer 330's built-in ArcReach® technology allows the Trailblazer 330 to communicate directly with a Miller ArcReach wire feeder or remote control through the welding leads, eliminating the need for costly control cables. Miller's exclusive AutoSet™ technology allows you to access pre-programmed welding parameters, based on metal thickness and welding process, for easy set up.  You can also fine tune your output amperage and voltage manually, to suit your welding style. 

The Miller Trailblazer® 330 features a Kohler® 23.5 horse power gasoline engine with Miller's exclusive Auto-Speed™ technology.  Auto-Speed matches the engine speed with the welding load. This means that the engine can run at optimum RPM rather than full RPM while under load. This translates into reduced fuel consumption, quieter operation and longer engine life.

The Trailblazer® 330 has the most smooth, stable welding arc in the business. It produces X-Ray quality welds whether you are using MIG, Stick or DC TIG welding processes.  For MIG welding, the 330 has a direct spool gun connection for Miller Spoolmatic® series and Spoolmate™ 200 spool guns, eliminating the need for a WC-24 weld control.  For stick welding, the Trailblazer 330's Dynamic Dig™ feature produces a consistent arc that is highly adaptive. Lift-Arc™ DC TIG with Quiet Pulse™ is standard on every Trailblazer 330, and produces outstanding results in TIG welding applications time after time.

Features

ArcReach® standard on all models - ArcReach® technology uses the existing weld cable to communicate welding control information between a Miller® ArcReach® feeder or ArcReach® Stick/TIG remote and Trailblazer® 330.
This technology eliminates the need for control cords, and their associated problems and costs.

Designed for the professional welder - The Trailblazer® 330 delivers unbeatable arc performance in all weld processes, providing the smoothest, most stable arc in the industry.

Auto-Set™ technology - Auto-Set offers predefined weld settings to increase ease of use and ensure that the job is done right for operators of all skill levels.

Ultra-adaptive arc control - Unlike conventional DIG that provides a preset amount of short-clearing current, Miller-exclusive Dynamic DIG technology works on a time-based algorithm that automatically adjusts the amount of current required to clear a short. Delivers a smoother more consistent arc that can be tailored to match application, material, fit-up and welder technique.

Lift-Arc™ DC TIG with Quite Pulse™ - DC TIG welding arc is initiated without the use of high frequency. Simply touch the tungsten electrode to the work piece and lift. Quiet Pulse pulsed TIG welding gives you superior control of the welding arc while eliminating the noise typically associated with pulsed TIG welding processes.

Direct spool gun connection - Connect a Miller Spoolmatic® Series or Spoolmate™ 200 spool gun directly to the welder. No need for a WC-24 weld control.

Smart-Cor™ technology - Independent weld and generator power in an improved, more compact design.
No interaction between jobsite tools and the welding arc, resulting in:
Stronger, cleaner, more efficient generator power
Reduced size and weight
Improved arc performance

Auto-Speed™ technology - Automatically adjusts the engine speed to run at lower speeds depending on the total power needed, resulting in:
Exceptional fuel-efficiency
Extended run times
Quieter operation
Reduced emissions

Innovative design - Engine is rotated to the front to create more efficient airflow, resulting in:
Quieter operation
Reduced size and weight
Easier maintenance

More portable, uses less truck space - Miller Trailblazer 330 welder/generators are up to 13% smaller and 80 lbs. lighter than previous models, which means moving them is faster and easier, for maximum productivity. And because they take up less space, Trailblazer welder/generators let work trucks carry more equipment and gear, so your work crews can be ready for anything.
