Miller Shopmate 300 Running Gear with Dual Cylinder Rack

Move Your Shopmate 300 with Ease

Stop struggling to move your welder and gas bottles separately. The Miller Running Gear (300145) is the ultimate upgrade for your Shopmate 300 or 300 DX, turning your stationary machine into a portable welding powerhouse. Whether you are working in a large fabrication shop or a garage, having the ability to roll your entire setup—welder, cables, and gas—directly to the workpiece saves time and saves your back.

Dual Cylinder Capacity

One of the biggest frustrations in welding is running out of gas in the middle of a bead or needing to switch processes (like MIG to TIG) and having to swap out heavy cylinders. This running gear solves that problem with a built-in Dual Cylinder Rack. You can keep two bottles mounted at all times—perhaps one 100% Argon and one C25 mix—so you are always ready for any job. The rack features strong safety chains to keep the bottles upright and secure, preventing accidental tips that could damage regulators or cause injury.

Built Miller Tough

Cheap universal carts often wobble or bend under the weight of a real industrial machine. This is genuine Miller equipment, built specifically for the weight and dimensions of the Shopmate 300. It features a wide stance for stability and heavy-duty steel construction that won't buckle. The large rear wheels glide over concrete expansion joints and stray welding leads, while the front casters let you steer the machine exactly where you need it. The handle is positioned at a comfortable height, giving you full control when moving the rig.

Key Benefits:

• All-in-One Station: Keeps your welder and gas together.
• Safety First: Securely holds two high-pressure cylinders.
• Easy Rolling: Heavy-duty wheels designed for shop floors.
• Perfect Fit: Bolts directly to your Shopmate 300 with no modifications needed.

Invest in the proper running gear for your machine and experience the freedom of bringing the weld to the work, rather than dragging the work to the welder.
