[j@j metal works]

I am Union Pipe Welder and understand how agervating it can be. I usually use a #10 cup. Hold the cup at about a 45 degree angle with your tungston sticky out about a 1/16 of a in. When you grip the torch, grip it lightly ( I use my thumb, index finger, and my middle finger). Try not to put pressure on the cup. I believe you may be comming too far up on the egde of your bevil, which is causing your stringer to suck back. Try to stay on the filler wire, you just want to touch the egde of each side. I also like to put and a nickle land on metal. It seems like you can carry a little more heat to me. If you can get a spare torch, go home and practice while you watching tv. Sometimes when your in a boot you can get a little tence, at home you are relaxed and motion will come second nature when your in the boot. I hope this helps.
