If DIP 3 is in the open (second stage) position, the schedule will
execute the SQUEEZE DELAY and SQUEEZE instructions, then
wait until the PS/SS input is made before executing any more
instructions.The guns will open and the sequence will stop if the
pilot is removed before the PS/SS input is made. If the pressure
switch is not made after five seconds, the message S_S will be
displayed on the DEP’s numeric display.

CLOSED = Reset faults by pilot
OPEN = Do not reset fault by pilot.
If DIP 4 is closed (reset faults by pilot), all faults will be cleared
when a new pilot is applied. If the stepper has ended and not
been reset, the STEPPER END fault will re-appear with the next
weld. If DIP 4 is open (do not clear faults with pilot) the control
will not initiate until all faults (except Compensation faults) have
been cleared at the DEP.

CLOSED = 87-degree delayed firing and automatic bleed
down enabled.
OPEN = 87-degree delayed firing and automatic bleed down
disabled.
When using Hypersil weld transformers, it is essential to use
delayed firing and automatic bleed-down to avoid saturation.
Saturation is characterized by a "grunting" noise coming from the
transformer. This noise is the sound of the transformer
magnetically tearing itself apart, which will eventually destroy it.
When a transformer saturates, less total current passes through
the part. This results in bad welds.
By contrast, stacked-iron transformers are very forgiving and
difficult to saturate. If full welding power is needed without
delay (as in a 1- or 2-cycle weld), then turn delayed firing (anti-
saturation) OFF. When seam welding, Hypersil transformers are
typically not used, and anti-saturation and automatic bleed down
are disabled.
