thank you all figured it out....it was the polarity......i was having a bad day :)

ive been using red tips (th) 1.6mm on mild steel

ive only been tigging for 6 months, but been a boily for 12 years. this is the first time ive had trouble with it. The tungsten keeps burnig back before i can start adding da filler rod..
been chatting with rthibeau and he told me that i might be holding it to close,the head might be dirty.
if anyone else has any other problem solving ideas it would be greatly appreciated. thanks for you time........:):cool:
