Hello
Would like to replace a mechanical contactor on welder with an electronic
switch, have access to high voltage high current SCR's, guess a TRIAC
would be the simple way to go, not really practical for 240 v. , 125
amp.A.C., If someone has been down this road before , I would appreciate
hearing from you.
Thanks
Phil

Phil.. Are you confusing input voltage and secondary output amps??
