6. CONTROL-REMOTE / LOCAL
• Two status lights indicate the location of output control as
pre-determined by the power sources auto-configure sys-
tem.
• The LOCAL display will be lit when control is at the power
source.
• The REMOTE display will be lit when a remote pot/control
is detected.
These Output Control configurations can be overridden
(switched) with the CONTROL push button. When
changed, the unit will power up in the configuration it was in
when it was last powered down.

7. WELD MODE SELECT - FACTORY AND
CONSTRUCTION (See Figure B.1)
The Mode Control button selects from the following
welding modes.
CC-STICK SOFT: The Stick Soft process features
continuous control ranging from 5 to 425 amps. This
mode was intended for most SMAW applications, and
Arc Gouging.
• Arc Gouging: Setting the output of the Stick Soft
mode to 425 amps will enable the arc-gouging
mode. The actual output current will depend on the
size of carbon used. The recommended maximum
size carbon is 5/16".
• The Hot Start control regulates the starting current
at arc initiation. Hot Start can be adjusted from min-
imum (0), with no additional current added at arc
start, to maximum (10), with double the preset cur-
rent or 425 amps (max of machine) added for the
first second after arc initiation.
• The Arc Control regulates the Arc Force to adjust
the short circuit current. The minimum setting (-10)
will produce a "soft" arc and will produce minimal
spatter. The maximum setting (+10) will produce a
"crisp" arc and will minimize electrode sticking.
CC-STICK CRISP:The Stick Crisp mode features
continuous control from 60 to 250 amps. This mode
was intended primarily for pipe welding applications.
• The Hot Start control regulates the starting current
at arc initiation. Hot Start can adjust starting current
up or down by 25% of the preset value. The recom-
mended setting for Hot Start is 5 where the initial
current is equal to the preset current.
• The Arc Control regulates the Arc Force to adjust
the short circuit current. The minimum setting (-10)
will produce a "soft" arc and will produce minimal
spatter. The maximum setting (+10) will produce a
"crisp" arc and will minimize electrode sticking.
CV-INNERSHIELD: The CV-INNERSHIELD mode
features continuous control from 15 to 29 volts. This
mode was designed for 5/64 NR 207 on Pipe Welding
Applications.
• The Hot Start control is not used in the CV-FLUX
CORED mode.
• The Arc Control regulates pinch effect. At the mini-
mum setting (-10), minimizes pinch and results in a
soft arc. At the maximum setting (+10), maximizes
pinch effect and results in a crisp arc.
The pinch control was optimized for NR207 at an
Arc Control setting of 0.0.
