hello guys . i want to add high frequency high voltage Arc starter feature to the cheap welder i have that i dont havem money to buy one with that feature.
my welder is DC inverter welder so the output curcuit in the welder as far as i can see is look like this
and i write some curcuit that i dont know if it will work or not. here it is.
now will the 300 V breakdown rated diode blow up if put a sparkgap in there ? i still want high voltage between clamps . so i put a mosfet in there too im thinking turn the welder power off while generating arc and turn the welder power on in the same time turn off the generator. but my mosfet is not high votlage rated either. so i dont know what to expect from this can spark gaps work for not break the diode and mosfet ? can you guys help me with this
