301239 - Miller Running Gear for Millermatic and Multimatic Welders

Professional Mobility and Gas Cylinder Management

The Miller Running Gear / Cylinder Rack (301239) is an engineered solution designed to enhance the functionality and portability of your compact Miller welding power sources. For professionals utilizing shielding gas processes—whether MIG (GMAW) or TIG (GTAW)—secure cylinder transport is a critical safety concern. This running gear is specifically constructed to address this need, featuring a robust cylinder rack capable of accommodating gas bottles up to 7 inches (178 mm) in diameter and weighing up to 65 lbs (29.5 kg). This capacity is ideal for standard 80 cubic foot cylinders, providing a perfect balance between gas supply duration and portability.

Constructed from heavy-duty steel, the chassis is built to withstand the rigors of industrial environments. The unit rests on a combination of 8-inch rubber rear wheels and durable front swivel casters. This wheel configuration is deliberate; the large rear wheels absorb vibration and navigate over floor imperfections, cords, and debris, while the front casters allow for precise steering and 360-degree rotation in confined workshop spaces. This ensures that your valuable welding equipment and high-pressure gas cylinders remain stable during transport.

Technical Compatibility and Expansion

This running gear is the OEM standard for a wide range of Miller and Hobart power sources. It is designed to bolt directly to the base of machines such as the Millermatic 141, 190, and 211, as well as the Multimatic 200, 215, and 220 series. It also supports the Diversion 165 and 180 TIG welders. For users requiring dual gas setups—common for those switching between steel (C25) and aluminum (Argon) or TIG processes—this cart is engineered to accept the Dual Cylinder Rack Conversion Kit (301454), allowing for future-proofing your setup as your welding capabilities expand.

Beyond mobility, the 301239 enhances workspace organization. It features dedicated cable management hooks to prevent lead damage and a specialized storage drawer for consumables, ensuring that contact tips, nozzles, and tungsten electrodes are always within arm's reach.
