Wire feed motor current monitoring system improves robotic welding performance

A large manufacturer produces parts for multiple vehicle types and uses welding guns throughout the plant.

  • The motor supplying wire feed to the gun often wears.
  • Irregular feed causes buckling and jams leading to unplanned stoppages and downtime.
  • The underlying cause is over-draw or under-draw current of the motor supplying the wire feed, but this parameter is often not monitored.

ifm’s moneo Real-Time Monitoring System improves robot welding performance by monitoring the current of weld feed speed to the welding gun. Overload and underload spikes are identified and allows the operator the opportunity to correct the wire feed for uninterrupted production.
