CV FCAW This setting has been optimized for
Innershield
electrodes.
CV GMAW Short circuit, glob and spray transfer
solid wire and gas welding are done in
this mode. Low end procedures, less
than 17V, may operate better in the
FCAW mode. Voltage in the GMAW
mode can become erratic when
welding is attempted using voltages
equal to or less than 17V DC+.

Output Terminals Switch
For processes and equipment that require energized
machine terminals (stick, TIG, air-carbon arc cutting or
hot tip LN-25), set the Output Terminals Switch to
"ON" position.
Set to the REMOTE (OFF) position when using LN-25
with K431 and K432 options or LN-7 which will allow
the gun trigger to energize the welding terminals.

Arc Force / Inductance Control
This control functions in all modes except GTAW. For
CC modes, this control acts as an Arc Force adjust-
ment. The arc is soft at the minimum settings and
more forceful or driving at the maximum settings.
Higher spatter levels may be present at the maximum
settings.
For CV modes, this control will set the degree of
"pinch effect" which predominantly affects short circuit
transfer. In FCAW, the maximum setting is generally
preferred. With GMAW, the upper half of the range is
preferred with CO 2 or high content CO 2 mixed. The
lower half is for inert gas mixes.
