300408 - Miller Inverter Running Gear Cylinder Rack for Axcess, Invision, and XMT Systems

Heavy-Duty Mobility for Industrial Welding Systems

The Miller 300408 Inverter Running Gear Cylinder Rack is an essential infrastructure component designed specifically for high-output industrial welding environments. Engineered to support the weight and dimensional requirements of Miller's advanced inverter power sources, this running gear provides a robust mobile platform for the Invision™ 352 and 456 models, Axcess® 300 and 450 systems, and the XMT® 456. In heavy fabrication settings where equipment stability and mobility are paramount, this cylinder rack ensures that your valuable power sources are securely mounted and easily transportable across the shop floor.

Constructed with industrial-grade materials, the running gear weighs approximately 215 pounds, reflecting its durability and capacity to handle heavy loads. It is designed to accommodate not just the power source, but a complete welding system. This includes mounting space for single or dual wire feeders and the Coolmate™ V3 cooling system, allowing for a fully integrated, water-cooled welding station on wheels. The low center of gravity design enhances safety when moving the unit, preventing tipping even when fully loaded with equipment and gas cylinders.

One of the standout features of this running gear is its dual cylinder capacity. It is engineered to hold two large gas cylinders securely, which is critical for operations requiring mixed gases or extended run times without frequent cylinder changeouts. The rear platform features secure chains and brackets to keep cylinders stable during transport. Additionally, the unit is designed with operator convenience in mind, featuring dedicated gun cable hangers to prevent cable damage and a built-in consumable drawer. This front-access drawer allows welders to store contact tips, nozzles, and drive rolls directly at the station, reducing downtime spent searching for parts.

By consolidating the power source, feeder, cooler, and gas supply into a single mobile unit, the Miller 300408 significantly improves shop organization and workflow efficiency. It transforms stationary equipment into a versatile mobile asset, ready to be deployed to any welding cell or fabrication bay as production demands change.
