  • Page 3 3.a. The electrode and work (or ground) circuits are electrically “hot” when the welder is on. Do not touch these “hot” parts with your bare skin or wet clothing. Wear dry, hole-free gloves to insulate hands. 3.b. Insulate yourself from work and ground using dry insulation.
  • Page 4 6.a. Remove fire hazards from the welding area. If this is not possible, cover them to prevent the welding sparks from starting a fire. Remember that welding materials from welding can easily go through small cracks and openings to adjacent areas. Avoid welding near hydraulic lines.

  • Page 10: Safety Precautions

    Dirt, dust, or any foreign material that can be drawn into the welder should be kept at a mini- mum. Failure to observe these precautions can result in excessive operating temperatures and nuisance shutdowns.

  • Page 11: Input Connection

    Using input wire sizes, fuses or circuit breakers smaller than recom- mended may result in "nuisance" shut-offs from welder inrush currents, even if the machine is not being used at high currents. INPUT VOLTAGE SELECTION Welders are shipped connected for 460 Volt input voltage.

  • Page 13: Recommended Electrode And Work Cable For Arc Welding

    RECOMMENDED ELECTRODE AND WORK CABLE SIZES FOR ARC WELDING General Guidelines Connect the electrode and work cables between the appropriate output studs of the FX450 per the follow- ing guidelines: • Most welding applications run with the electrode being positive (+). For those applications, connect the electrode cable between the wire drive feed plate and the positive (+) output stud on the power source.
  • Page 14 SAFETY PRECAUTIONS Read this entire section of operating instructions before operating the machine. WARNING ELECTRIC SHOCK can kill. • Unless using cold feed feature, when feeding with gun trigger, the electrode and drive mechanism are always electrically energized and could remain energized several seconds after the welding ceases.

  • Page 15: Operation

    • Simple user interface - designed with the operator in mind. Getting setup for the weld is several clicks away and even the most novice welder can be confi- dent he is setup properly. • F.A.N. (fan as needed). Cooling fan runs when the output is energized and for a 5 minute cool down period after output is disabled.

  • Page 19 Amperage Display Meter • Prior to STICK or TIG operation (current flow), the meter displays preset current value. • Prior to CV operation, the meter displays four dash- es indicating non-presettable AMPS. • During welding, this meter displays actual average amps.
  • Page 20 GTAW This weld mode is a constant current (CC) mode featuring con- tinuous control from 10 – 500 amps. It is intended for the GTAW TIG welding processes. Hot Start - The Hot Start control regulates the starting current at arc initiation. Hot Start can be set to “Off” and no additional current is added at arc start.
  • Page 21 CV-INNERSHIELD This weld mode is a constant voltage (CV) mode fea- turing continuous control from 10 to 45 volts. It is intended for the FCAW-SS welding process and arc gouging. Hot Start – Toggle to “ON” position to provide more energy during the start of a weld.
