18. Gas Inlet
5/8-18UNF gas inlet for the shield gas.
19. Control Cable Socket
The control cable connects to the power source at this 19-
pin amphenol connector. It contains the signals required to
allow the welding power source and the wire feeder to work
together as a system.
WARNING
The protective earth ground (pin G) of the control cable
is established ONLY when the power source is properly
grounded. See the power source owner’s manual for
proper grounding methods.
20. Welding Cable Connector
This connector allows us to connect the welding cable to the
Wirefeeder. Please make sure that Weld connection is firmly
secured, or connection could overheat and cause damage.
NOTE
It is essential to make a good connection by pushing it
all the way in and turning it to lock it into place.
21. 4A Circuit Breaker
This circuit breaker protects the Wirefeeder from electrical
faults on the 115VAC circuit. In the event of a fault occuring
this circuit breaker will trip (pop out). A short cooling period
must be allowed before an attempt is made to reset it by
pressing it back in. Refer to Section 5.02 for further details.
