trigger again to weld another weld bead.
REMOTE CONTROL
A remote control (ref. 045675) can be connected to the EXAFEED wire feeder via the connector (FIG-1, 5). The remote control acts on the voltage
(1st potentiometer) and the wire speed (2nd potentiometer). Thus these settings cannot be accessed on the wire feeder’s interface.
