7. When all impulses are complete, DOWNSLOPE TIME is
executed. Downsope starts at the Welds Current value and
slopes down to the Slope End current value over the
Downslope time in line cycles. Turn off Downslope Time by
entering a value of 0.
8. Next, TEMPER (a post-heating) may be applied to the weld
nugget by using the parameters entered for Temper Cycles
and Temper Current. Use TEMPER to slow the cooling of the
nugget and help prevent cracks in the weld. To turn off
TEMPER, enter 0 cycles.
9. Then, HOLD TIME will pause in sequence, guns closed, for
the programmed time. This gives the weld nugget time to
fully solidify.
10. The welding process is now complete. All that remains is to
de-energize the valve and release the work piece. The valve
will be de-energized by one of two of the three remaining
functions, SUCCESSIVE or OFF. CHAIN SCH will not de-
energize the valve. As soon as the valve is de-energized,
WELD COMPLETE (if programmed non-zero) will energize
the WCOMP output for the number of line cycles specified.
Note: The WCOMP output will not be issued until the valve
is off and Off Cyc is programmed 0 (i. e. single mode, non-
repeat), or SUCCESSIVE is programmed non-zero.
11. After the weld process is complete, the SUCCESSIVE SCH
instruction (if programmed non-zero) will turn off any valve
that was previously selected and wait for the pilot to be
removed. If the pilot for the same schedule is re-applied, a
branch to the VALVE instruction of the schedule that is
programmed in SUCCESSIVE SCH will occur. If a different
schedule is re-applied, the active sequence is ended and the
"new" schedule is started. SUCCESSIVE SCH is used to make
a series of different welds on a single part. SUCCESSIVE SCH
allows up to 60 different weld schedules using the same pilot.
A string of successive schedules may be ended in any of three
ways:
1. End normally by programming the last weld schedule’s
SUCCESSIVE instruction 0.
2. Apply a pilot that calls a different schedule outside the
successive program.
3. Abort the successive sequence of schedules in progress by
this procedure:
a. Press and release the PROGRAM key until the
Sequence and Config column LEDs are both OFF.
b. Press and hold the FAULT RESET key.
