Miller Gold Star® 452 230/460/575 V903400:


Superior Arc Welding Provides versatility and outstanding arc performance in CV (MIG) and CC (stick, TIG, CAC-A), and Flux-cored (FCAW)
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.
Thermal Overload Protection Helps prevent machine damage if the duty cycle is exceeded or airflow is blocked.
Line Voltage Compensation Ensures consistent weld performance by keeping output power constant even if primary input power varies by ±10 percent.
Hot Start™ Makes it easy to start difficult stick electrodes such as E-6010 and E-7018.
Power Efficient For exceptional value and return on your investment.
115-Volt Duplex Receptacle Provides 15 amps of auxiliary power.
Thermal Overload Protection Helps prevent machine damage if the duty cycle is exceeded or airflow is blocked.
Power Cord Strain Relief Provided for your convenience at installation.
Fan-On-Demand™ The cooling system operates only when needed. Reduces contaminants drawn into the machine and excess noise in work areas.
Optional Digital voltmeter and Ammeter are easy to read, even at 30 feet (9.2 m).
Simple Control Panel Features single range amperage/voltage adjustment. Provides easy and efficient operation.
14-pin Receptacle Provides quick, direct connection to Miller 14-pin wire feeders and accessories.
Enclosed Circuit Boards Provides additional protection from contaminants
resulting in a longer service life.
PC Board Protection Prevents the wire feeder power or other stray voltages (less than 115 VAC) from harming the power source PC board.
