I have just bought a Tig welder, and allready I have some questions!
(1st) When sharpening tungstens, how critical is the finish on the point?? I am using a 180 grit diamond wheel and looking at the finished point with a loupe, the point isnt at all smooth,and the striations left on the point arentcompletely in line with the tungsten(depending on how fast the tungsten is spun. Chucking the tungsten in a drill really makes it worse) Also when flatting the point, bits of tunsten are left on the tip ready to fall off. I have been taking those bits off with a piece of 240 wet or dry paper, however I recall a comment somewhere on the internet saying not to use that kind of sanding paper on tungstens????
(2nd) What does "Walking the cup" accomplish?? I was watching a tutorial, and it seems that one of the requirements would be that the weldor have at least a triple jointed wrist!! When using this procedure, is the cup rolling on the weld bead??? It seems that one of the results would be a wider bead.
Any and all inputs will be greatly appreciated!!!!
