• Symptoms

  42
  • Major Physical or Electrical Damage is Evident.

    42
  • No weld output and no auxiliary power. Engine runs normally.

    42
  • No weld output in AC or DC Modes. The auxiliary power (480, 23 & 115 VAC) is normal. Engine runs normally.

    43
  • No DC welding output. AC welding output and auxiliary power is normal.

    43
  • No AC welding output. DC welding output and auxiliary power is normal.

    44
  • No constant voltage (CV) welding output. Constant current (CC) and the auxiliary power are operating normally.

    44
  • Engine will not go to high idle when attempting to weld or when the auxiliary power is loaded. Welding output and auxiliary power output is normal when Idler Switch is in the“HIGH” position.

    45
  • Engine will not go to high idle when attempting to weld. Welding output is normal when Idler Switch is in “HIGH” position. Automatic idle function works properly when the auxiliary power is loaded.

    45
  • Engine will not idle down to low speed. Machine has normal weld output and auxiliary power.

    46
  • Engine will not crank or cranks very slow.

    46
  • The Engine shuts off.

    47
  • Engine does not develop full power.

    47
  • Engine tries to start when S3 is in start position, then shuts off when switched to run.

    47
  • Engine will not start with S3 in start position, but then tries to start or does start when S3 is switched to run position.

    47
  • Engine will not shut off when S3 is placed “OFF” position.

    47
  • Engine continues to crank when S3 is switched to “RUN” position.

    47
  • The welding arc is “cold.” Engine runs normally (3700 RPM no load). Auxiliary power is functioning normally.

    48
  • Welding output is low with little or no control. Auxiliary output is also low.
