Miller CP-302 Wire Feeder

What are the specifications for the Miller CP-302 Wire Feeder?

The Miller CP-302 is a MIG power source with a voltage range of 14–44 VDC and rated output of 300 A at 32 VDC with 100% duty cycle. It measures 30 x 23 x 30.5 inches and weighs 332 lb, featuring large analog meters, a 14-pin receptacle for quick wire feeder connection, and 115-volt power for tools and coolant systems.

What input amperage does the CP-302 require at different voltages?

At rated output, the CP-302 requires the following amps input at 60 Hz: 38 KVA (33 KW) at 200V, 33 KVA (30 KW) at 230V, and 16.5 KVA (15 KW) at 460V. The manual does not specify input requirements for 575V.

How does the CP-302 maintain consistent welding performance?

The CP-302 features Line Voltage Compensation technology that ensures consistent weld performance even when primary power varies. This allows the machine to maintain stable output across different electrical supply conditions.

What is the Fan-On-Demand cooling system?

The Fan-On-Demand™ Cooling System operates only when needed rather than continuously, which reduces contaminants drawn into the machine and minimizes excess noise in work areas. This helps maintain cleaner equipment and a quieter work environment.

What protection does the CP-302 have against overheating?

The CP-302 includes Thermal Overload Protection that indicates power shutdown to prevent machine damage if the duty cycle is exceeded or airflow is blocked. This safeguard helps protect the equipment from damage due to overheating conditions.

How do I connect a wire feeder to the CP-302?

The CP-302 features a 14-pin receptacle that provides a quick, direct connection to Miller wire feeders. Simply insert the feeder connector into this receptacle for proper connection.
