For both the Construction and Factory versions,
these trigger modes can be over-ridden (switched)
with the WELD TERMINALS push button. When
changed, the unit will power up in the configuration it
was in when it was last powered down.
5. THERMAL
• This status light indicates when the power source
has been driven into thermal overload. If the output
terminals were "ON", the "ON" light will blink indi-
cating that the output will be turned back on once
the unit cools down to an acceptable temperature
level. If the unit was operating in the "REMOTE"
mode, the trigger will need to be opened before or
after the thermal has cleared and closed after the
machine has cooled down to an acceptable temper-
ature to establish output.
6. CONTROL-REMOTE , LOCAL
• Two status lights indicate the location of output
control as pre-determined by the power sources
auto-configure system.
• 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 overrid-
den (switched) with the CONTROL push button.
When changed, the unit will power up in the configu-
ration it was in when it was last powered down.
Hidden Middle Control Panel – Process
Set Up Panel
The middle control panel is removable to allow for
upgrades (see Field Installed Options/Accessories).
Additionally, this panel is hidden by an access door
to reduce appeared complexity and provide protection
to the controls.
7. WELD MODE SELECT
The Mode Control button selects the following weld-
ing modes desired.
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 maxi-
mum size carbon is 5/16".
• The Hot Start control regulates the starting current
at arc initiation. Hot Start can be adjusted from
minimum (0), with no additional current added at
arc start, to maximum (10), with double the preset
current 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 5 to 425 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 cur-
rent up or down by 25% of the preset value. The
recommended setting for Hot Start is 5 where the
initial current is equal to the preset current.
