.
If a remote control is connected to the
Remote 14 Receptacle and used for
amperage adjustment, the adjustment
will function as a percentage of the pre-
set amperage. The Remote In Use indi-
cator will be lit.
.
If an ArcReach device is used for am-
perage adjustment, it will have full
range of the preset amperage. If using
an ArcReach device capable of com-
munication while welding, the amper-
age can be adjusted while welding. De-
pendent on the capabilities of the de-
vice, it may have the ability to override
parameter adjustments and mode
switch setting. The Remote In Use indi-
cator will be lit. An ArcReach device will
override a remote control connected to
the Remote 14 Receptacle.
.
For best results at the end of the weld,
pull back the electrode quickly to extin-
guish the arc.

See Section 9-5 for information regard-
ing Alternate Configurations.
Arc Control
Pressing the Arc Control button will cause
the Arc Control Indicator to light. Dependent
on the setting: the STIFF or SOFT indicator
will light and STIF or SOFT will appear on
the Left Display. 0 to 25 will appear on the

Right Display. If set to 0 neither STIF or
SOFT will appear.
Rotate Adjust Control to select desired Arc
Control setting from 0 to 25 Soft and 0 to 25
Stiff. Minimum Arc Control setting is Soft 25.
Maximum Arc Control setting is Stiff 25.
Mid-range adjustment of 0 is good for most
applications.
Arc Control allows the arc characteristics,
soft versus stiff, to be changed for specific
applications and electrodes. Lower the Arc
Control setting for smooth running elec-
trodes like E7018 and increase the Arc
Control setting for stiffer, more penetrating
electrodes like E6010.
After three seconds of inactivity the Adjust
Control will revert back to adjusting preset
amperage.
.
While in Air Carbon Arc (CAC−A)
mode, Arc Control is not adjustable.
Hot Start Time
Press and hold the Arc Control button until
HOT.S appears on the left display. Rotate
Adjust Control to enable Automatic Hot
Start Time (AUTO) or to set Hot Start Time
from Min (0.1 seconds) to Max (5.0 sec-
onds). A separate Hot Start Time may be
set for EXX18 and EXX10 modes.
After three seconds of inactivity the Adjust
Control will revert back to adjusting preset
amperage.
.
While in Air Carbon Arc (CAC−A)
mode, Hot Start Time is not adjustable.
