20 Pressure rings

Pressure rings for the reliable processing of welding wire from drums They serve as pay-off discs in winding drums and thus prevent the upper coils in the wire container from slipping or forming loops


Pressure rings protect the wire in winding drums during transport by pressing down on the coil thus preventing slippage of the upper coils in the wire container.
When unwinding from the container, the pressure ring guides the wire and prevents looping.
