i have just set up my tig a hobart 250a tigawave.
i have never tig welded before, how do you know wjhat size electrodes tungstons and ceramic covers to use? there must be a easy way, i assume the larger the current the larger the shroud???
i have sucessfully stuck the tungston to the metal several times, how much should stick out of the shroud please.
what settings for the argon should i use at present i have tried 120amp and 30psi
all your help would be aappreciated
