FC-5B EHD FOOT OPERATED
REMOTE CURRENT AND CONTACTOR CONTROL
This remote control is designed for use with any power source
that employs a single (common) current and contactor control
14-pin Amphenol 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 when the PRS is
placed in the “Remote” position. Both the potentiometer and
switch are operated when the FC-5B EHD pedal is depressed.
See the schematic diagram in your respective power source
instruction literature.
Interconnection of these functions to the main power source is
provided by a single mating 30-ft. cable/plug assembly pro-
vided.
Make sure all primary power to power source is
disconnected before installing this control.
By depressing the foot pedal, the weld-start sequence circuit
will energize, and the welding current will increase or decrease
semi-linearly within the range preset on the power source “Cur-
rent” control potentiometer.
To use the remote control, proceed as follows:
Plug the FC-5B EHD control cable into current/contactor
control receptacle on the power source.
Set the Remote/Panel toggle switch to the Remote posi-
tion.
Set the Current Control on the power source panel to the
maximum current range to be used.
Depress the foot pedal as desired to weld.
