300909 - Miller Off-Road Running Gear for Bobcat & Trailblazer (Gas/LP)

Heavy-Duty Mobility for Industrial Welders

The Miller Off-Road Running Gear (300909) is a specialized mobility solution engineered specifically for Miller Bobcat™ and Trailblazer® engine-driven welders. Designed to withstand the rigors of industrial environments, this running gear transforms stationary welding generators into portable units capable of traversing uneven and rugged terrain. The assembly features four heavy-duty 15-inch pneumatic tires equipped with inner tubes. Unlike solid tires, these pneumatic wheels provide superior shock absorption, protecting the internal components of the welder from excessive vibration during transport across gravel, dirt, or construction debris.

Structurally, the running gear is built to accommodate the specific weight distribution and frame dimensions of gas and LP-powered models. It is compatible with Miller Bobcat 225 and 250 models manufactured after January 2012, as well as Trailblazer 275 and 325 models produced after September 2012. The inclusion of a rugged, ergonomic handle allows operators to maneuver the unit with precision, ensuring that the welding power source can be positioned exactly where it is needed on the job site. This running gear is an essential accessory for field fabrication, pipeline maintenance, and agricultural repair applications where paved surfaces are non-existent.

Compatibility Specifications:

• Miller Bobcat™ 225 (Mfg. after Jan 2012)
• Miller Bobcat™ 250 (Mfg. after Jan 2012)
• Miller Bobcat™ 250 EFI (Mfg. after Jan 2012)
• Miller Trailblazer® 275 (Mfg. after Sept 2012)
• Miller Trailblazer® 325 (Mfg. after Sept 2012)
• Hobart Champion™ Elite (Mfg. after Jan 2012)

Please note that this specific running gear configuration is optimized for Gas and LP models. It is not intended for use with diesel engine models or in conjunction with gas cylinder mounting assemblies. The robust frame construction ensures long-term durability, while the large diameter wheels significantly reduce the rolling resistance encountered on soft ground.
