2.05 General Information
The ULTRAFEED A 2000 is a semiautomatic, Variac
controlled wire feeder capable of a 100% duty cycle. The
system offers both load and line voltage compensation
helping to maintain a constant wire feed speed, even with
changes in the input voltage and/or load. The wire feeder
comes complete with a wire spool support assembly.
The ULTRAFEED A 2000’s sheet metal box totally encloses
the solid state control circuitry. A hinged, latched
feedhead cover allows quick and easy access to the
feedhead featuring tool-less quick change feed rolls.
The ULTRAFEED A 2000 comes with an abundance of
standard features including:
• an on/off rocker switch
• a circuit breaker for total system protection
• a wire feed speed control
• an inch switch
• a gas purge switch
• electromechanical brake for precise wire stopping
• two quick change, gear-driven feed rolls
The ULTRAFEED A 2000 has been designed to comply
with CSA NRTL/C, NEMA EW 3, and IEC 60974-1
standards.
