9.4 SQUEEZE DELAY APPLICATION
Some applications require the welder arms be opened wide to allow the electrodes to access
areas to be welded. Squeeze Delay was designed for use with welding guns and stationary
machines incorporating standard air cylinders and valves without retraction features. The
additional time provided by the Squeeze Delay will allow the electrodes to travel a greater
distance and simulate the retraction function. Squeeze Delay is only active in the first
Schedule in a Repeat Sequence.
9.4.1
SQUEEZE DELAY
OPERATION
Setting the control for Squeeze Delay will provide additional time before the programmed
"Squeeze time" in all schedules. The Squeeze LED indicator on the control panel will dim
slightly during the programmed Squeeze Delay time. Squeeze Delay time occurs only
during the first “Squeeze” of a series of repeated welding sequences (Repeat Mode).
Squeeze Delay will be present in all schedules even if no other data has been entered.
Squeeze Delay is not intended for use with Seam or Anti-Tie Down modes of operation.
If not required set [
=!J!
] to [
""
].

PROGRAMING
1. Press the SELECT push button repeatedly until the Function indicator has advanced past
SLOPE COUNT to enter data in the EXTENDED FUNCTIONS [
01

2. Move through the EXTENDED FUNCTIONS until [
=!J!
] appears in the DATA Display.
3. Press the PROGRAM/OPERATE push button to place the control in the PROGRAM
mode.
4. Press the DATA push buttons until the desired Squeeze Delay time, in cycles, is
displayed.
5. Press the ENTER push button to store the desired data.
6. Select and enter Cycle Mode [
"#
] (Repeat).
7. Adjust SQUEEZE and OFF time to allow the electrodes to open only a short distance
between repeated welding sequences.
8. Press the PROGRAM/OPERATE push button to put the control in the Operate Mode.
