First I do not have any affiliation with him or his site , but I do find his videos great for learning and info...
I bought 2 of his tig fingers and they work great . I found that on long runs I can use one on my torch finger and also just lay one down under my left hand when feeding rod and it really keeps the heat away but most of all they let your hand slide real easy when feeding rod.
Anybody else using these?
