- Symptoms
- Major mechanical or electrical damage is evident.
- No welding output or auxiliary power. The engine operates normally.
- No welding output in any mode. The auxiliary output is normal. The engine operates normally.
- No output in PIPE MODE. Outputs normal in other modes.
- VRD lights don’t light up.
- No auxiliary power at one or more receptacles or at the 14 pin Amphenol. Weld output is normal and the engine operates normally.
- The machine has low welding output and low auxiliary output.
- The machine will weld but the welding arc is “COLD”. The engine runs normally and the auxiliary power is normal.
- The machine will weld but the welding arc is “COLD”. The engine runs normally and the auxiliary power is normal. (continued)
- The machine welds but it will not maintain a steady output.
- The machine welds but it will not maintain a steady output. (continued)
- The weld output can not be adjusted with the front panel output control knob in one or mode weld modes. The weld output terminals have normal OCV (open circuit voltage). The AC auxiliary power is normal and the engine operated normally.
- The machine front panel output control is still active when the remote control unit is connected to one of the Front Panel Amphenols.
- The machine seems to be locked into the “CC-stick” mode of operation.
- The arc quality is poor with excessive spatter. The arc heat can be controlled and maintained normally, the auxiliary output is normal and the engine operates normally.
- The machine welds normally in all modes and the range of weld output seems normal, but one or both of the front panel displays is blank, incorrect welding value, or displays parts of numbers.
- A control cable type feeder does not function when connected to the 14 pin amphenol. Machine operates normally in the “CC-STICK” mode and has normal AC auxiliary output.
- An Across-the-Arc type wire feeder does not function when connected to the weld output of the machine. The Vantage® operated normallyin the CC-STICK mode, and has normal AC auxiliary output.
- The engine will not crank when the start button is pushed.
- The battery does not stay charged.
- The engine cranks when the startbutton is pressed but will not start.
- The engine starts but shuts down immediately when the start button is released.
- The engine shuts down shortly after starting.
- The engine shuts down shortly after starting.
- The engine shuts down shortlyafter starting and trips the battery circuit breaker (CB5).
- The engine will not develop ful lpower.
- The engine will not idle down to low RPM. The machine has normal weld and auxiliary output.
- The engine will not idle down to low RPM. The machine has normal weld and auxiliary output. (continued)
- The engine will not idle down to low RPM. The machine has normal weld and auxiliary output. (continued)
- The engine will not go to high idle when using auxiliary power. Auxiliary power is normal when the idler switch is in the “HIGH” idle position, the automatic idle function works properly when welding.
- The engine will not go to high idle when striking arc. The automatic idle system functions normally when using auxiliary power. Welding and auxiliary outputs are normal when the idle switch is in the “HIGH IDLE” position.
- The engine will not go to high idle when attempting to strike and arc, or when a load is applied to any of the auxiliary power receptacles.
- The engine goes to low idle, but will not stay low idle.
