OVERVIEW

Heavy-Duty Mobility for Rugged Environments

The Miller 300912 Off-Road Running Gear is an essential accessory for professionals operating Miller Bobcat or Trailblazer engine-driven welders in demanding environments. Engineered to withstand the rigors of construction sites, pipelines, and agricultural settings, this running gear system provides superior mobility and protection for your welding power source. The assembly features a robust protective cage that wraps around the machine, shielding it from accidental impacts, falling debris, and the general wear and tear associated with heavy industrial use. Integrated cable holders within the cage design ensure that welding leads and cables are stored securely during transport, preventing tangles and damage.

Never Flat™ Tire Technology

One of the standout features of this running gear is the inclusion of four heavy-duty 15-inch Never Flat™ tires. Traditional pneumatic tires are prone to punctures from nails, scrap metal, and sharp rocks common on job sites, leading to frustrating downtime and maintenance. The Never Flat™ technology eliminates this risk entirely, ensuring that your welder is always ready to move when you are. These large-diameter wheels also provide excellent ground clearance and shock absorption, allowing the unit to roll smoothly over gravel, mud, ruts, and uneven terrain that would bog down standard casters or smaller wheels.

Compatibility and Specifications

This running gear is specifically designed for compatibility with gasoline and LP models of the Miller Bobcat and Trailblazer series, as well as the Hobart Champion Elite. Please note that it is not intended for use with diesel models. The unit weighs approximately 175 lbs and adds significant stability to the welder with its wide footprint. The dimensions of the shipping package are 39 inches in length, 31 inches in width, and 12 inches in height. By investing in the Miller 300912, operators ensure their equipment remains mobile, protected, and efficient, maximizing productivity on every project.
