Two New Miller Welders

Posted on January 9, 2014

Miller Electric Mfg. Co., the Appleton, Wis.-based manufacturer of arc welding and cutting equipment, has introduced two welder/generators powered by Tier 4 final Kubota diesel engines.

The Trailblazer 325 diesel welder/generator is designed to extend runtimes by up to 55% and reduce fuel use by as much as 25% compared to the Trailblazer 302, the diesel model it replaces, said John Van Meter, product manager for Miller.

The second new welder, Bobcat 250 diesel is designed for mobile maintenance trucks and now features a smaller and lighter enclosure. It replaces a previous Bobcat 250 machine.

Many of the upgrades in the gasoline Trailblazers were incorporated into the new diesel version, including Smart-Cor and Auto-Speed technologies. Smart-Cor is designed to provide independent weld and generator power, ensuring no interaction between the welding arc and jobsite tools.

In the previous machines, operators could weld and generate power, but with two separate generators. The new Trailblazer accomplishes the same job with one generator, which reduces the size and weight of the unit, Van Meter said.

Auto-Speed automatically adjusts the engine to run at lower speeds depending on the total power needed, Van Meter said. The system adjusts the engine speed to the load requirement, Van Meter said.

In earlier machines, the engine would run at 3600 rpm regardless of the load. The new Trailblazer has four operating speeds — 2400, 2800, 3200 or 3600 rpm — depending on the load required.
