No welding current or intermittent welding current

Possible cause:

  • Check if the blank cutting is correct.
  • Check if the overlap is correct and constant.
  • Check the welding sensor B6.
  • Check the welding pressure sensor S31:
    • depending on your version S31 is a pressure sensor or a reed switch!
  • Check if the wire has no dent’s (mechanical damage for example due to too big can gap).
  • Check all terminals at the Pacemaker board.
    • > wait for 5 minutes after switching off the unit.
  • If you can weld a canbody with only main current and the error occurs quiet often, you can try the following:
    • a) remove the welding sensor.
    • b) start production and cover the sensor by hand, as soon as canbodies are welded.
