CONTROL CABLE CONNECTIONS

• All control cables can be connected end to end to
extend their length.
The control cable connecting the wire feeder to the
power source is specially made for the welding envi-
ronment.
The wire feeder power requires overcurrent protec-
tion. Connect the wire feeder only to power sources
with overcurrent protection of no more than 15 amps.
