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
at 4-7 psig.
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. Release the four latches to open the hinged side cover.
3. Loosen the jam nut holding the 1/4-20 cap screw in place.
4. Rotate the small, knurled, threaded rod upward until the Pressure Switch
closes.
5. Next rotate the cap screw down until the Pressure Switch opens.
6. Rotate cap screw down one turn past the Pressure Switch open position.
7. Tighten the jam nut to lock cap screw in position.
8. Close the hinged side cover and secure latches.
9. Plug the power supply into the electrical source.
10. Cycle the welder.
The press is now set to trigger at the minimum trigger pressure of 4-7 psig.
A press actuating in an upward or horizontal direction should be set to trigger
at a minimum of 8-10 psig. Lower values may affect trigger performance
where false triggering may be observed.
