Two-Level Foot Switch Connector
When you press the foot switch to the first level, the Power Supply energizes the air actuated weld head.
This causes the upper electrode to descend and apply force to the weld pieces. If you release the foot
switch before pressing it to the second level, the Power Supply will automatically return the upper
electrode to its UP position so that you may re-position the weld pieces.
If you do not release the foot switch at the first level and proceed to the second level, the force-firing
switch in the weld head will close. Weld current will flow, and the Power Supply will automatically return
the upper electrode to its UP position.
Using the supplied Configuration plug on Pins 11 – 20 allows the use of the AMADA WELD TECH 2-
level footswitch directly. If a PLC or other means of trigger is used, refer to the
I/O Signal Interface
