2.6 ADDITIONAL REMOTE CONTROL (J2)
INTERCONNECTION
A.
For non-digital conventional MIG operations. This
8-pin remote control receptacle (J2) can be used
to provide full-range remote voltage regulation
from the HC-3B or HC-4B hand control. Note that
the power source’s Panel/Remote switch must
be set to REMOTE to provide this feature. When
connected, the HC-3B's or HC-4B’s process
switch must be set to its CV-MIG position to
provide constant voltage (cv) operation and volt-
age regulation from its potentiometer. Also re-
member that the contactor switch is nonfunc-
tional for this process — contactor control is
provided by the torch switch through receptacle
J1.
B.
For Stick, TIG, or Arc Gouging operations (see
Figure 2-3). These processes require constant
current (cc) characteristics for proper operation,
and this is only provided when one of the remote
control accessories (FC-5B or TC-2B) is con-
nected to receptacle J2, or when the HC-3B or
HC-4B hand control is connected to J2 and its
process switch is set in the CC-TIG/STICK posi-
tion. Note that the power source’s Panel/Remote
switch must be set to REMOTE to provide cur-
rent regulation and/or contactor control at the
welding location. When the FC-5B foot or TC-2B
torch accessory is connected, full-range current
regulation and contactor control are available
from the remote accessory.
When the HC-3B hand control is connected, the
process switch must placed in the CC-TIG/STICK
position to set up the power source for constant
current operation. Remote current regulation is
provided from the CURRENT potentiometer. The
CONTACTOR control switch must be placed in
the ON position to provide welding power to the
torch/electrode.
If the HC-4B hand control is connected, you must
place its Process switch in the CC position to set
up the power source for constant current opera-
tion. Remote current regulation (up to full range)
is provided from the CURRENT control potenti-
ometer. The CONTACTOR control switch must
be placed in the ON position to provide welding
output current to the torch/electrode. The HC-4B
also incorporates two additional control features;
a TIG/Stick selector and an Arc Force potentiom-
eter that functionally operates in the STICK mode.
The TIG and Stick modes provide the same cc
type volt-ampere curve characteristic; however,
the slope of the STICK curves can be further
adjusted by regulating the Arc Force control pot.
The lower Arc Force settings provide less short
circuit current and a softer, more stable arc;
whereas the high settings provide more short
circuit current and a forceful, more penetrating
arc.
