I was bored and found used high voltage transformer that has 7.5kv output for cheap, i have old ac stick welder that serves me no use.
My idea is: add a simple on/off switch to primary of hv transformer and use that a on/off switch for welding, maybe add a capacitor if needed.
Next connect the two secondary vires that carry hv one to ground clamp and another to valve torch so the voltage never drops to zero and arc never cuts out and I can mantain long enough arc for tig welding.
Will i need spark gap?
I know this is fire hazard and pointless but Im bored and have a fire extinguisher
Hope this inst fftopic: or
