Miller 4-Pack Rack for CST and Maxstar Welders

Heavy-Duty Multi-Operator Solution for CST and Maxstar Welders

The Miller #951934 4-Pack Rack is a specialized enclosure engineered for the professional demands of the Miller CST™ 282 and Maxstar series power sources. Designed for high-density welding applications such as shipbuilding and construction, this rack system allows for the operation of up to four inverters from a single primary power drop. This significantly reduces the amount of primary cabling required on the job site, minimizing voltage drop issues and decluttering the work area. The enclosure is constructed to meet the rigorous needs of field construction, providing a sturdy structure that shields the power sources from the inevitable knocks and drops of industrial work.

Electrical Integration and Common Grounding

One of the standout technical features of this rack is the Common Output Ground Connection. This feature allows welders to connect to a single ground point for the entire rack, provided all machines are operating with the same polarity. This simplifies the secondary cable setup and ensures consistent grounding across the arc welding operations. Additionally, the rack includes a built-in Junction Box that manages the power distribution to the individual machines. It comes pre-equipped with fuses for 460 V operation, ensuring your equipment is protected against electrical faults. Note that if your site operates on 220-230 V or 575 V, specific fuses for those voltages must be ordered separately to match your input power.

Versatile Mobility and Installation

Mobility is a critical factor in dynamic welding environments. The Miller 4-Pack Rack is equipped with a comprehensive set of transport features. The standard Lifting Eye is rated for the weight of the fully loaded rack, enabling crane transport to elevated decks or remote areas. Fork Pockets are integrated into the base frame for secure forklift handling, and the standard Running Gear allows for local positioning by hand. The open-frame design ensures adequate airflow for the cooling systems of the installed inverters while maintaining structural integrity. This rack is an essential accessory for maximizing the duty cycle and lifespan of your Miller CST and Maxstar fleet by keeping them off the ground and properly secured.
