907700 - Miller XMT 450 ArcReach 4-Pack Rack System (Fused 460/575V)

High-Capacity Industrial Welding Solution

The Miller XMT® 450 CC/CV ArcReach® 4-Pack Rack (907700) is engineered to meet the rigorous demands of large-scale construction, shipbuilding, and infrastructure projects. This integrated system houses four XMT 450 power sources within a heavy-duty, galvanized steel rack, offering a centralized power solution that is both rugged and efficient. Designed for portability, the rack features standard lifting eyes and fork pockets, allowing for easy repositioning around the jobsite using cranes or forklifts. The system is fused specifically for 460/575 V input, enabling a single primary power drop to supply all four welders, which drastically reduces cable clutter and electrical setup time.

ArcReach® Technology for Enhanced Productivity

At the heart of this system is Miller's ArcReach® technology, which transforms the way operators interact with their equipment. By allowing voltage and amperage adjustments to be made directly at the wire feeder or remote—without the need for a separate control cord—ArcReach eliminates the time-consuming trips back to the power source. This is particularly beneficial in complex environments like shipyards or multi-story construction zones where the power source may be located hundreds of feet away. Additionally, Cable Length Compensation (CLC™) ensures that the delivered voltage matches the set voltage, regardless of cable length, ensuring consistent weld quality.

Rugged Durability and Versatility

The XMT 450 Rack is built to withstand the harshest environments. It meets IP23 standards, offering superior protection against water and foreign objects compared to standard IP23S or IP23M ratings. The rack's roof and shelves are fabricated from galvanized steel and painted to resist corrosion, while liquid-tight strain reliefs protect internal electrical connections from saltwater, oil, and solvents. With a rated output of 450 amps at 100% duty cycle and the ability to handle Carbon Arc Gouging with up to 5/16-inch carbons, this system delivers the power and reliability required for heavy industrial fabrication.
