When in the AC ACTIVATION screen (
Fig. 27 ), simply
press button D ( Fig. 11 ) to activate AC mode.
The first adjustment you can make after activating AC
mode is balance.
Fig. 28 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 final screen in this menu.
You can now adjust your asymmetric arc. You can limit
the EP (Electrode Positive) amperage here. In Fig. 30 , 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. 31 .
When in the menu shown in
Fig. 31 , press button C ( Fig.
11 ; SELECT in this instance) a few times to move the
black arrow next to Asymmetric set: Ep - En. To change
from Ep to En, or vice versa, press button
D ( Fig. 11 ;
CHANGE in this instance) until the value you want to
limit is highlighted. Then, press button
E ( Fig. 11 ; the
green checkmark in this instance) to confirm. You should
end up on the screen shown in Fig. 32 .
The top right corner of the LCD now shows AC
POLARITY in red and also shows the frequency and the
balance values in black (
Fig. 32 ). The frequency and the
balance values shown in black indicate that the
Asymmetric arc function is not active.
