In the following example, solenoid valve 1 will be the standard valve and solenoid valve 2
will be the forging valve. The total weld time is 15 cycles at 95 percent current with the
forging valve activated after 10 cycles.

NOTE:
For Forge during weld it is possible to select a percent current for the first schedule
and a different percent current for the second schedule.
Other combinations of weld schedules may be combined to create other FORGING
schedules. For example it would be possible to use UP SLOPE in the first sequence and
Pulsation in the second sequence.

WELD CURRENT DELAY provides a time delay and output to the machine solenoid valve
circuit. When the weld wheels are lowered, a delay before weld current is applied is required
to insure the wheels are together and sufficient pressure is attained. WELD CURRENT
DELAY is represented by squeeze time on the front panel. To add WELD CURRENT
DELAY to a SEAM sequence, add SQUEEZE time to the first schedule of the SEAM
sequence. If the sequence is programed for INTERMITTENT SEAM or ROLL SPOT the
programed SQUEEZE time will only be in effect upon initiation.
To return the control to SPOT mode, the EXTENDED FUNCTION [SE] Mode must be
selected. See section 7.3 EXTENDED FUNCTIONS. Use the SCHEDULE SELECT Push
Buttons (20 & 21) and SCHEDULE Display (22) to select [SE]. With the control in the
PROGRAM Mode enter a 00 into the DATA Display (4) using DATA Push Buttons (5 &
6). As typical of other data entry the ENTER Push Button (29) must be depressed to load the
desired data.
