When I start production the pendulum head runs, but wire drive does not start (wire slips on the welding disc)

  1. Try to move the tension cylinder / cylinders by hand back and forward, without air pressure and wire.
  2. Try to turn lower welding roll (without wire) by hand.
  3. Check the groove of the upper welding disc.
  4. Is the wire width correct?
  5. Adjust the pressure of the tension cylinders: Cylinder below wire profiling unit requires 1.6 bar. Cylinder (behind main alu-plate) for wire chopper unit requires 2.0 – 2.4 bar.
