Issued April 2016 • Index No. DC/13.0 MIG Welding Power Source Industrial Applications Quick Specs Input Power 3-phase power Light fabrication Automotive Furniture Agricultural Truck body/metal fabrication Small equipment manufacturing MIG (GMAW) Flux-cored (FCAW) Rated Output 300 A at 32 V, 100% duty cycle 390 A at 32 V, 60% duty cycle Max. Open-Circuit Voltage 14–44 VDC Net Weight 332 lb. (151 kg) Adjustable weld stabilizer (high-low inductance) provides the flexibility to produce the optimal arc characteristics. Use the high stabilizer setting for stainless steel and low setting for mild steel and aluminum. Build your own system at MillerWelds.com/equiptoweld or see the stationary and MIGRunner packages (page 3). Large analog volt and ammeters for easy viewing. Solid-state weld contactor provides longevity to match the ultra-durable and reliable reputation of the CP series. Presettable welding voltage with voltmeter allows you to easily set weld output before welding. Power efficient for exceptional value and return on your investment. Simple control panel with just one control adjustment. 115 VAC duplex receptacle provides 15 amps of auxiliary power. Lower panel cover protects output connections from harsh welding environments. 14-pin receptacle provides quick, direct connection to wire feeders and accessories. CP-302 MIGRunner ™ package shown. Welder is warranted for three years, parts and labor. Original main power rectifier parts are warranted for five years.
