lol i take it you where touching metal with you skin. if the welder has high frequency and your notot touching metal you can start a arc on your skin and it does not hurt you. its not really a arc per say. it looks like lighting bolts coming from the tungsten to your skin. if your touching metal then it feels like little zap.
if the metal your touching has the ground cable on it then your in a world of pain.
my old welding teacher saw i guy blow his thumb up like a hot dog blows up, split down the center. the guy was showing the trick of starting a arc on his hand to a new guy at the place they where working. his hand was to close to the table the current went from his tungsten then to the table.
the high frequency makes the arc jump from the tip of the tungsten to the metal so you dont have to strike a arc like, with arc welding. also when you tig welding on ac it's used so when it's switching back and forth it wont lose its arc.
up date i finish making the pictures i need for my bending guide. the write up will be done by Sunday. i had a few people offer to edit my work who still wants to.
