Waveform Check and Weld Fire Lockout
Even though the Power Supply optimizes the output pulse, misaligning parts or operating at the outer
edges of the Power Supplies operational range may degrade the waveform. The
WAVEFORM CHECK
feature, which includes
STABILITY CHECK
and
ENERGY CAPACITY LIMIT,
can be used to confirm
that the proper waveform was produced.
The
WELD FIRE LOCKOUT
feature guarantees that the capacitor bank is charged to a user defined
percentage before the Power Supply is allowed to fire. This advanced feature prevents poor welds caused
by operating at too high of a repetition rate, which can deplete the capacitor bank charge.
These features are totally independent of Weld Monitor features described in Chapter 3 of this manual.

1
From the
WAVEFORM CHECK
menu,
press the
2
key to access the
STABILITY CHECK % LIMIT
screen.
2
Use the numeric keypad to enter the %
limit. This limit is the allowable average
deviation from the set point for the weld
pulse after the delay period.

to return to the
WAVEFORM CHECK
menu. The
STABILITY CHECK % LIMIT
line
will display your programmed setting
along with deviation readings from the
Pulse 1 and Pulse 2 of the most recent
weld.
