I've read a book on Tig and this is my first attempt. I've laid my first bead on 0.8mm mild steel sheet.
Questions:
If I contaminate the tip by touching the filler on it while welding is it enough to grind it down? Whats the symptom of a tungsten that needs replacing?
Do I need to keep the filler rod within the gas to stop it oxidising? If I accidentally take it too far out should I stop?
When I stop, the tip of the filler rod has had the copper coloured coating burnt off. Do I need to trim this off?
