2.05 General Information
The ULTRAFEED VA 4000 is a semiautomatic, solid state
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 that
must be installed in the field.
The ULTRAFEED VA 4000’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 quick change feed rolls, and tool-less
knobs and clamps for changeover of guides and guns.
The ULTRAFEED VA 4000 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
• a power source voltage control
• an inch switch
• a gas purge switch
• a 2 step / 4 step selector switch
• PC board adjustments for enhanced runin control
• a solid state electronic brake for dynamic braking
• four quick change, gear-driven feed rolls
• a gas valve solenoid
• a low voltage gun trigger circuit for operator safety
• a variety of add-on options to configure the unit for
any wire-welding situation.
The ULTRAFEED VA 4000 has been designed to comply
with CSA NRTL/C, NEMA EW 3, and IEC 60974-1
standards.
