10) HOW TO WELD—STEP BY STEP
a) STICK
Use the Select Mode button ( Fig. 11, A ) to toggle through
the menu until the LED next to STICK illuminates. You
are now in the stick welding mode.
Plug the electrode holder (stinger) into the desired
outlet (most stick electrodes use DCEP, which requires
the electrode holder to be plugged into the positive
output receptacle (
Fig. 2, W )) and the ground clamp into
the negative output receptacle ( Fig. 2, Z ). Use the
encoder F ( Fig. 11 ) to set your welding amperage,
which is shown in the LCD.
Fig. 12 shows a selected welding amperage of 120
amps. When you strike an arc, the LCD changes and
shows the actual welding amperage and the arc voltage.
Pressing button
B ( Fig. 11 ) gives you the option to
activate AC mode.
In order to activate AC mode, simply press button
D
( Fig. 11 ).

The first adjustment you can make after activating AC
mode is balance.
Fig. 1 4 shows 70% EN (Electrode
Negative). Using encoder F ( Fig. 11 ), you can change
the balance value from 10 to 90%. Once you select the
desired balance for your application, press button
C ( Fig.
11 ; the green arrow in this instance) to enter the next
screen.
You can now adjust your AC frequency. From 4 to 99
amps of welding current, you can adjust the frequency
from 20 to 400Hz, and from 100 to 400 amps of welding
current, you can adjust the frequency from 20 to 200Hz.
Pressing button
C ( Fig. 11 ; the green arrow in this
instance) takes you to the last screen in this menu.
You can now adjust your asymmetric arc. You can limit
the EP (Electrode Positive) amperage here. In
Fig. 16 ,
the asymmetric arc value is set to 100%, so EP is not
limited in this instance; however, you can limit EP to
increase penetration. If you do not want to limit EP, but
would like to limit EN instead, press button
E ( Fig. 11 )
to enter the submenu in Fig. 17 .
