Abstract: In a consumable electrode arc welding process different combinations of the various parameters (open circuit arc voltage, wire feed speed, series inductance, shielding gas) are stored on a plug board by interconnecting each input bus with preselected output buses. The input buses are connected through a selector switch to a voltage source. As the selector switch is moved through its different positions a voltage is applied to the different input buses in turn. The output buses are connected to relays which control the selection of the different parameters.

Abstract: Different preselected combinations of the values of welding parameters in a consumable electrode arc-welding process are obtained when a selector switch is moved through its different positions. The switch is inserted into the hub of the reel of electrode wire which is to be fed to the welding torch. The reels are coded so that the switch is moved to a position which will select a combination of values appropriate for the wire carried by that reel.
