Electromagnet Vibrator is Not Working

Has the welding current destroyed cables or circuits within the frequency generating equipment?

That would be my immediate guess. Welding and electronics are usually not good cohabitants

Here it is (before attempting please check voltage/ frequency ratings):

1. You can directly feed A/C mains of 50/ 60 Hz and run the feeder for initial setting purpose. So bypass the pulse generator and set the bowl feeder first.
2. Ensure that you have assembled the mechanical parts exactly same as before.
3. There will be a gap between lower magnetic core and upper core. Set the gap properly. You can ensure proper gap by hit & trial.

Once the feeder bowl vibrating and feeding the material now you can connect back pulse generator. I am not sure what type of vibrating element you are using. There are many types and I gave the above advice assuming that your vibrator got 110V/ 230V magnetic core.

i didn't burn or damaged any wire or the circuit. i just did welding on the tray. i change the clearance also several times. feeding is working properly at certain time period and sometimes it won't work!. could anyone tell me whether the fault is in the circuit or else?

i will mail a photo on Monday. please help me!

will the problem is in the pulse circuit? how can i check the circuit.

could you provide me the pulse generating circuit diagram.

Damage would not need to ne in the form of mechanical or thermal extremes to the metal, but rather the intense electro-magnetic energy from the welding electrodes imparted upon the sensitive electronics that are involved in the pulse generation.

Unless maybe you did gas welding?
