Programming Squeeze Time
Users of Air Operated Weld Heads which do not have force-firing switches may use the Squeeze Time
feature. Squeeze Time begins when the 125DP recognizes an Air Head Connection and a Footswitch
closure (the first Level of a 1-Level Footswitch or the second Level of a 2-Level Footswitch). See
Chapter 2, Installing Air Actuated Weld Heads. After the Squeeze Time has elapsed the 125DP will
fire. It is not necessary to make a Firing Switch connection when using Squeeze Time.
Use the following procedure to program Squeeze Time:
a Press 1ST PULSE PROGRAM. The 125DP must be in the PROGRAM state to program Squeeze
Time. Any Schedule number can be displayed. Squeeze Time is a system parameter and will
be used by all weld schedules.
b Press 1ST PULSE PROGRAM again and hold. The ENERGY DISPLAY will display SQUEEZE
TIME in seconds. The PROGRAM indicators will go out while Squeeze Time is displayed.
c Press ENERGY while holding 1ST PULSE PROGRAM to change Squeeze Time. Squeeze
Time can be set from 0.1 to 9.9 seconds. To disable set at 0.0.

return to RUN state.
