Mesa 7i96s torch on/off connection

Looks like HF start so can start in air, but brings a horror show of EMI issues.

They are the same, look the same, the only thing missing is the "pilot" terminal in lower front.
Also, chinese specifications do not help, they are a total mess usually.

I will have to look again. But either way I just need a pinout for the Torch ON/OFF on the mesa board.

How its connected depends on what the 7I96S is driving.

If the 7I96S is driving a relay with less than 100 mA of current
I would use 7I96S OUT5. Also a relay needs a flyback diode.
This may be included in the torch control switch wiring in
the plasma source.


 

Thank you
