Processes Stick (SMAW) TIG (GTAW) Air Carbon Arc (CAC-A) Cutting and Gouging Flux Cored (FCAW) MIG (GMAW) Spray Transfer when using a Voltage-Sensing Wire Feeder Heavy Industrial Applications Steel Erection Pipe Welding Tank/Pressure Vessel Fabrication Maintenance/Repair Shipbuilding Construction Refineries Chemical Manufacturing Facilities Steel Manufacturing Facilities Foundries Quick Specs Gold Star® Series Stick Welding Power Source Issued Dec. 2010 • Index No. DC/8.1 Built-in arc control lets you get in tight without sticking the electrode. An electrode compensation circuit ensures consistent arc control performance regardless of the electrode size. Superior arc welding performance with Stick and TIG welding. Power efficient for exceptional value and return on your investment. Fan-On-Demand™ operates only when needed reducing noise, power consumption, and the amount of airborne contaminants pulled through the machine. The Power of Blue®. Power source is warranted for 3 years, parts and labor. Original main power rectified parts are warranted for 5 years. Input Power 3-Phase Power on all models Rated Output 302/402: 300 A at 32 VDC, 60% Duty Cycle 452/602: 450 A at 38 VDC, 60% Duty Cycle 652/852: 650 A at 44 VDC, 60% Duty Cycle Weight 302/402: 352 lb (160 kg) 452/602: 404 lb (183 kg) 652/852: 505 lb (229 kg) 115 VAC duplex receptacle provides 15 amps of auxiliary power. Hot Start™ makes it easy to start difficult Stick electrodes such as E-6010 and E-7018. Simple control panel features single range amperage adjustment. Provides easy, efficient operation. Optional digital meters for voltage and amperage. Large displays are easy to read, even at 30 ft (9.2 m). Line voltage compensation ensures consistent weld performance by keeping output power constant even if primary input power varies by ±10%. Gold Star 452/602 Power cord strain relief provided for your convenience at installation. Enclosed circuit boards provide additional protection from contaminants resulting in longer service life. Thermal overload protection light indicates power shutdown. Helps prevent machine damage if the duty cycle is exceeded or airflow is blocked. PC board protection prevents the wire feeder power or other stray voltages (less than 115 VAC) from harming the power source PC board. 14-pin receptacle provides quick, direct connection to Miller 14-pin remote controls and switches.
