CHANGING AND SETTING WELD MODES
To select a weld mode, press the WELD MODE
SELECTOR button until the WELD MODE indicator
comes ON (it may already be lit by default at power
up). Turn the control knob to select the desired mode.
After about 1 second, the parameters for the new
mode will be displayed. These parameters can be
adjusted with the control knobs below each display.
NOTE: CC Modes will show AMPS in the upper left
display. CV Modes will show wire feed speed
and the WFS indicator will be lit.
FREQUENCY/BALANCE CONTROL
FREQUENCY ADJUST
Press the WELD MODE selector until the FREQUEN-
CY/BALANCE indicator comes ON and the MSP
Display reads “Frequency”. If the selected mode
allows for frequency adjustment, the Control Knob can
be used to select the desired frequency between 20
and 100hz.
Frequency adjustment can be used to fine tune stabili-
ty of imbalanced waveforms and multiple arc system.
BALANCE ADJUST
Press the WELD MODE selector until the MSP
Display reads “Balance”. If the selected mode allows
for balance adjustment, the Control Knob can be used
to select the desired wave balance through a range of
25% to 75%.
Adjusting the Balance (the ratio between Positive and
Negative half cycle ‘on time’) changes the deposition
for more efficient welding.
OFFSET ADJUST
Press the WELD MODE selector until the MSP
Display reads “Offset”. If the selected mode allows for
offset adjustment, the Control Knob can be used to
select the desired offset. The amount of offset allowed
is determined by the selected weld mode.
Independent control of the Positive and Negative
cycles allows for more precise control of penetration
and deposition.
