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 indicator LED 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 modes of operation. If not required, set
S.d.S.d.
