Miller Xmt 450 Cc/Cv Arcreach Welder W/Aux Power (907481004)

The XMT 450 CC/CV ArcReach is a high-output power source built for heavy industrial work, with a 115-volt auxiliary receptacle on the back for running coolant systems or other support gear without a separate generator. ArcReach lets an operator control voltage and amperage from the wire feeder, and a 14-pin connection takes spool guns, feeders, or remote controls.

Output and control

Amperage climbs as high as 600, with the duty cycle rated at 100 percent for 450 amps on three-phase power. Once ArcReach communication is active, the system locks out process and amperage changes at the power source, so only the operator at the feeder or remote can adjust settings, then that lock releases automatically once the ArcReach connection ends. Input runs on 230 or 460 volts, three-phase only.

What it handles

This configuration covers aluminum, mild steel, and stainless steel across stick, MIG, TIG, flux-cored, and air carbon arc cutting and gouging work, with 1/2-inch stud connectors. The auxiliary receptacle sits behind a 10-amp circuit breaker. Miller rates this unit for career-level welders running heavy industrial jobs rather than light or home-shop use.

Q: What does the auxiliary receptacle power? It is meant for coolant systems or similar support equipment running alongside the welder, not for powering the arc itself.

Q: Can a spool gun plug into this machine? Yes, the 14-pin connection on this power source takes spool guns along with feeders and remote controls.

This new unit weighs roughly 125 pounds, carries Miller's three-year warranty, and has a California Prop 65 notice on file; confirm the exact shipping weight with us before ordering. See our welding equipment range for lighter power sources if 600 amps is more than your work needs.
