Lower welding roller moves too much down during welding

Possible causes:

  • T-Z-bar broken
  • Z-bar cooling insufficient (if not existing on your welder, ask us for a upgrade kit)
  • Welding frequency too high (ask us for a Pacemaker upgrade: change from triangle to sine wave welding)
  • Not enough cooling water (check proper adjustment of water flow switches)
  • Cooling water too warm
