Abstract
Feeder spool for arc-welding electrode wire comprises a suitably controlled drum and a pressure-roller used to hold the wire elastically against the periphery of the drum. The presure-roller can be displaced in the opposite direction to that of the electrode wire to operated a suitable electric switch when the tail-end of the wire passes a line between the axes of the drum and the pressure-roller. The displacement of the pressure-riller in the same direction as the wire is pref. restricted by an adjustable stop mounted on an eccentric pivot, and the switch is pref. a microswitch operated by the end of the shaft on which the pressure roller is mounted. The system provides a signal, when the end of the electrode wire is reached, to automatically warn the operator and/or switch off the welding current and the feeder motor.
