Spot Repeat
A spot weld with repeat is a single point where the squeeze, weld, hold profile is repeated multiple times. A Spot Repeat
weld is typically used in stitch welding applications where an operator may keep the foot pedal engaged to repeat the
weld program. The electrodes will open during the OFF sequence which allows the workpiece to be repositioned for the
next weld.
A weld sequence timing diagram showing a spot repeat weld with the air valve actuated by the iPAK2v2 weld controller
and the squeeze, weld, hold sequence repeated while the START input is maintained (see
).
The weld program options are set as follows:

The timing sequence follows the order of operations defined below:
1)
The Start input is initiated and maintained on.
2)
Pre-squeeze and squeeze time for the actuator to reach the desired weld force.
3)
The main heat weld current is applied
4)
The hold sequence is executed
5)
The off sequence is executed and the WAV signal is off which allows the electrodes to open
6)
The START input is still maintained, so the squeeze weld hold sequence is repeated
7)
The off sequence is executed and the WAV signal is off which allows the electrodes to open
8)
The START input is still maintained, so the squeeze weld hold sequence is repeated
9)
The off sequence is executed and the WAV signal is off which allows the electrodes to open
10)
The START input is no longer maintained
11)
The program is exited
