Afternoon Folks,
Firstly, I am still relatively new to TIG so everything I do is pretty much practice (currently on a level 2 college course) but Tig sometimes gives me a small jolt up my filler hand and I'm not sure why? Any ideas?
I initially thought it may be sometimes when i lose a tight gap between the tungsten and the workpiece and the lengthen gap increases the voltage enough to "fizz" my hand?
Also, this afternoon when finishing up making my aluminium roof rack my welds started to go to ****...took me way too long realise they were contaminated as i just thought the new positions for me were too challenging... when i came to clearing up i realised my gas was in the red and mostly empty.... i disconnected the feed and purged the canister but it still had a fair amount of pressure...does that mean i wasn't out or is the last of the gas of lesser quality?
Sorry for the massive post!
