ESAB FC-5C Foot Operated Remote Current and Contactor Control Instruction manual

INSTRUCTIONS for

This remote control is designed for use with any ESAB
Tig type power source that employs a single (common)
current and contactor control receptacle. It contains a
potentiometer, which controls the current output when
the Panel/Remote Switch (PRS) on the power source is
placed in the “Remote” position. This remote control also
consists of a switch which controls contactor operation
at the weld station when the PRS is placed in the “Re­mote” position. Both the potentiometer and switch are
operated when the FC-5 pedal is depressed. See the
schematic diagram in your respective power source in­struction manual.

Interconnection of these functions to the main power
source is provided by a single mating 25-ft. cable/plug
assembly provided.
