What to do if the Entron EN1000 sequences but will not weld?
- H
  Hannah WeaverAug 17, 2025
  If the Entron Controller sequences properly but does not weld, first check any external weld/no weld switch or the WELD/NO WELD switch on the front panel, ensuring proper operation and secure wiring. If no external switch is present, use a jumper across NW1 & GND. Then, verify the welding transformer is connected to the lugs in the control (H1 and H2). Inspect for corroded or open connections, ensuring the welding electrodes close on the workpiece. If issues persist, the Terminal Strip/Firing PCB or the Control/Display PCB may be defective and need replacement with a board of the same A/N. Also check for missing phase.

Why does the solenoid valve chatter on my Entron Controller?
- K
  Kimberly WoodAug 20, 2025
  If your Entron Controller initiates and sequences properly, but the solenoid valve chatters, there are several potential causes. First, ensure that the valve supply voltage is not varying below -15% tolerance and that the valve coil has the correct voltage. Also, check for sufficient air pressure and loose connections in the valve wiring. If these steps don't resolve the issue, the Control/Display PCB or the Terminal Strip/Firing Board may be defective and need replacement. Refer to the Wiring Diagram for the correct A/N when replacing boards.
