951883 - Miller CST 282 4-Pack Rack Welding System 208-575V Tweco

Advanced Multi-Operator Power Source Rack

The Miller CST 282 4-Pack Rack (951883) is a sophisticated solution designed to meet the rigorous demands of industrial construction, shipbuilding, and infrastructure projects. This system consolidates four CST 282 power sources into a single, rugged enclosure, streamlining logistics and power distribution on the job site. Engineered for versatility, the rack features Miller's proprietary Auto-Line™ technology, which allows the units to connect to any primary input voltage ranging from 208 to 575 volts, single- or three-phase, 50 or 60 Hz, without manual linking. This ensures consistent performance regardless of power fluctuations or dirty input power often found in field environments.

Precision Arc Control and Connectivity

At the core of this system is the CST 282's superior arc performance, specifically calibrated for critical welding applications. It offers distinct settings for XX10 and XX18 electrodes, with "stiff" and "soft" arc characteristics available for each. This level of control is essential for pipe welding and out-of-position work where arc stability is paramount. The rack utilizes a Miller-exclusive Universal Connector System, currently configured with Tweco-style connectors, but easily convertible to Dinse-style without opening the machine. This flexibility allows operators to adapt to existing cable inventories seamlessly.

Rugged Design and Logistics

The rack enclosure is built to withstand harsh industrial environments while maintaining a small footprint and low weight (330 lbs total). It is designed to fit into standard elevators and features a lifting eye for crane transport, making it ideal for multi-story construction. The system includes a common output ground connection for same-polarity use and a single main disconnect box with fused circuit breaker switches for each machine, ensuring safety and ease of isolation during maintenance.
