PRESSURE SWITCH ADJUSTMENT
For systems mounted in the normal vertical position with downward travel, no
adjustment should be necessary. The minimum trigger pressure is factory set
to approximately 10-12 psig (69 kPa/.7 bar - 83 kPa/.8 bar).
However, if the minimum trigger pressure requires recalibration or re-
adjustment, observe the following procedure:
1. Maintain air pressure and unplug the power supply from the electrical
source.
2. Remove the four screws holding the five-sided cover.
3. Loosen the jam nut holding the 8-32 cap screw in place.
4. Rotate the cap screw counter-clockwise (up) until the Pressure Switch
closes.
5. Next rotate the cap screw clockwise (down) until the Pressure Switch
opens.
6. Rotate cap screw clockwise (down) 1/4 turn past the Pressure Switch
open position.
7. Tighten the jam nut to lock cap screw in position.
8. Replace the cover and four screws.
9. Plug the power supply into the electrical source.
10. Cycle the welder.
A press actuating in an upward direction should be set to trigger at a minimum
of 14-16 psig (a value which is nominally factory set only if “Sonics” is notified
prior to purchase that the press will be used for vertical welding). Lower
values may affect trigger performance where false triggering may be
observed.
