6.3 INCORRECT ROTOR HOME POSITION
If the rotor is not stopping in the correct home position the ce
nter pin will not operate.
If a weld is started when the rotor is not at home, a damaging arc out can occur. To
correct this situation:
1. With the jaws open and the power supply in TEST mode, send the rotor home.
2. Insert a 1/16” pin into the “Home Position Locator” (Ref Section 4.0, Item 6) to
depress the home switch release.
3. While holding this pin in the hole, jog the rotor into the correct home position.
4. Remove the 1/16” pin.
5. Send the rotor home again.
6. Check home position and repeat as necessary.
