How to check welding pressure assembly?

  1. Remove welding pressure and check if deviation of upper (outer) rollerhead (in most machines the pendulum rollerhead) is working properly (free of any mechanical friction or resistance)!
  2. Follow 1. and check „copper belts“ (the flexible power conductors between the rollerhead and the upper bus bar) and that they are not give mechanical resistance (counterforce) to the welding pressure.
  3. Following 1. and make sure that the „lift“ of the upper rollhead is not disabling the welding pressure to be fully obtained to the lower welding roll. This can happen if the both welding roller diam. are smaller than allowed.
  4. Finally check, ideally with a „tension spring balance“, the actual welding force (usually it should be within 40–45 daN)
