Subarc DC Series Issued August Index No. DC/9. Submerged Arc Welding Power Source Quick Specs Heavy Industrial Applications Railcar Shipbuilding Heavy Fabrication Pipe Manufacturing Pressure Vessel Processes Submerged Arc (SAW) Stick (SMAW) Air Carbon Arc Cutting and Gouging (CAC-A) Input Power Requires -Phase Power Rated Output /: A at VDC, % Duty Cycle /: A at VDC, % Duty Cycle /: lb ( kg) /: lb (9 kg) The Power of Blue. DC multiprocess capability provides versatility and outstanding arc performance in SAW (Submerged Arc) and CC (Stick, Carbon Arc Gouging). Internal digital voltage control (DVC) enables operator to preset weld voltage in the CV mode before striking an arc. 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. Hot Start makes it easier to start difficult-to-start Stick electrodes such as E- and E-. Line voltage compensation ensures consistent weld performance by keeping output power constant even if primary input power varies by ±%. Simple control panel features single range amperage/voltage adjustment. Provides easy, efficient operation. Digital voltmeter and ammeter are easy to read, even at ft (9. m). Subarc DC shown. Thermal overload protection light indicates power shutdown. Helps prevent machine damage if the duty cycle is exceeded or airflow is blocked. -pin receptacle provides quick, direct connection to Miller -pin wire feeders and accessories. V duplex receptacle provides amps of auxiliary power. Remote on/off capabilities allow operator to turn power source on/off from a distance. Remote voltage control allows operator to change voltage from SAW Control. 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. Enclosed circuit boards provide additional protection from contaminants resulting in longer service life. Power cord strain relief provided for your convenience at installation. Power source is warranted for years, parts and labor. Original main power rectified parts are warranted for years. Miller Electric Mfg. Co.
