22nd August 2019, 09:16Howcome the 200v 1A method would only yield a 1-2mm arc? Carbon electrodes put out copious UV and heat which readily ionizes gasses. The CC...32 replies | 694 view(s)

22nd August 2019, 04:16That is a hazard which can be removed with a series resistor to the pot or using a voltage divider instead of the pot. But the question was...6 replies | 230 view(s)
