- Symptoms
- Both the weld and auxiliary output voltages are low.
- There is no, or very low weld output, and no auxiliary output.
- There is no, or very low weld output voltage. The auxiliary output is normal.
- There is no auxiliary voltage, weld output is normal.
- The output takes a long time to build up and the AC auxiliary voltage varies when the fine current control is adjusted.
- The weld output is considerably less than indicated on the dials or varies abnormally. Auxiliary output appears normal.
- The weld output is considerably less than indicated on the dials or varies abnormally. Auxiliary output appears normal.
- The weld output is considerably higher than indicated on the dials. Auxiliary voltage appears normal.
- The welding arc is loud and spatters excessively.
- The welding arc frequently “popsout”. Welding heat seem snormal and auxiliary output voltage appears normal.
- The engine will not crank when the start button is pressed.(Classic® 300G and 300D Perkins)
- The engine will not crank when the start button is pressed. (Classic® 300D Kubota)
- The engine will not crank when the start button is pressed. (Classic® 300D Kubota)
- The engine cranks when the start button is pressed, but will not start.(Classic® 300G and Classic®300D Perkins)
- The engine cranks when the start button is pressed, but will not start.(Classic® 300D Kubota)
- The engine starts normally, but shuts down after running for several seconds.
- The engine will not develop full power.
- The engine will not shut down when the run/stop switch is moved to the stop position.
- The battery does not stay charged.
- The machine will not idle down to low RPM when weld and auxiliary loads are removed. The machine has normal weld and auxiliary output. The engine starts and shuts down normally.
- The machine will not idle down to low RPM when weld and auxiliary loads are removed. The machine has normal weld and auxiliary output. The engine starts and shuts down normally.
- The engine goes to low idle, but will not stay at low idle. The machine has normal weld and auxiliary output. The engine starts and shuts down normally.
- The engine goes to low idle, but will not stay at low idle. The machine has normal weld and auxiliary output. The engine starts and shuts down normally.
- The engine will not go to high idle when the idle switch is moved to the “High” position. The idle system functions normally while welding or using auxiliary power. The engine starts and shuts down normally.
- The engine will not go to high idle when striking an arc or when using auxiliary power. The engine goes to high idle, and the weld and auxiliary power are normal when the idle switch is in the “High Idle” position. The engine starts, runs, and shuts down normally.
- The engine will not go to high idle when striking an arc. The automatic idle system functions normally when using auxiliary power. Weld and auxiliary power are normal when the idle switch is in the “High Idle” position. The engine starts ,runs, and shuts down normally.
- The engine will not go to high idle when using auxiliary power. The automatic idle system functions normally when welding. Weld and auxiliary power is normal when the idle switch is in the “High Idle” position. The engine starts, runs, and shuts down normally.
