Operation
While the Amps Indicator is lit under the
Right Display, the Adjust Control is used to
set desired preset amperage.
Pressing the Setup Button allows adjust-
ment of Arc Control, Hot Start Current, and
Hot Start Time.
�
For best results at the end of the weld,
pull back the electrode quickly to extin-
guish the arc.
Arc Control (Dig)
Press the Setup Button so the Arc Control
indicator is lit. DIG appears on the Left Dis-
play, and the corresponding dig setting ap-
pears on the Right Display.
Rotate Adjust Control to select desired dig
setting from 0 to 100.
Dig control allows the arc characteristics,
soft versus stiff, to be changed for specific
applications and electrodes. Lower the dig
setting for smooth running electrodes like
E7018 and increase the dig setting for stiffer,
more penetrating electrodes like E6010.
Press the Setup Button repeatedly until the
Arc Control light goes out to return to adjust-
ment of preset amperage.

Programmable Hot Start
Press the Setup button repeatedly until
HOT. S appears on the left display. HOT. S
adjusts the Hot Start Amperage to Adaptive
Hot Start (AUTO) or from Min (1) to Max
(50). Adaptive Hot Start (AUTO) automati-
cally chooses a default amperage. The Min
(1) setting results in no hot start amperage.
Higher numbers result in higher start
amperage.
Press the Setup button again so HOT.T ap-
pears on the left display. HOT.T adjusts the
Hot Start Time to Adaptive Hot Start (AUTO)
or from Min (1) to Max (50). Adaptive Hot
Start (AUTO) automatically chooses a de-
fault time. The Min (1) setting results in no
hot start time. Higher numbers result in lon-
ger start time.
Press the Setup button to return to adjust-
ment of preset amperage.
�
Use this mode for Air Carbon Arc
(CAC-A) cutting and gouging. For best
results, adjust dig setting to maximum.
