B-6 OPERATION B-6
BALANCE ADJUST
Press the WELD MODE selector until the MSP Display reads
“Balance”. If the selected mode allows for balance adjust-
ment, 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.

FIGURE B.14 - WELD SEQUENCE
WELD SEQUENCE (See Figure B.14)
The weld sequence defines the weld procedure from beginning to
end. All adjustments are made through the user interface.
START OPTIONS
The delay, strike, start and upslope parameters are used at the
beginning of the weld sequence to establish a stable arc and provide
a smooth transition to the welding parameters. They are described
in the following:
• ARC DELAY inhibits the wire feed for up to 5 seconds to provide
an accurate weld start point. Typically used in multi-arc systems.
• STRIKE settings are valid from the beginning of the sequence
(Start) until the arc is established.
They control run-in (speed at which the wire approaches the work-
piece) and provide the power to establish the arc. Typically output
levels are increased, and WFS is reduced during the strike portion
of the weld sequence.
• START values allow the arc to become stabilized once it is estab-
lished. Extended start times or improperly set parameters can
result in poor starting.
• UPSLOPE TIME determines the amount of time it takes to ramp
from the start parameters to the weld parameters. The transition is
linear and may be up or down depending on the relationship
between the start and weld settings.
