I have a question for my Tig'ers. We repair molds at my shop. And have to weld up Beryllium copper pinch. I understand how toxic this stuff is, and we are well ventilated here. My question is, what method and set up would you use to get a fine bead on top of the pinch. In most cases, the pinch is only low by maybe .002. and we have to weld the top, then machine it back to a proud state. We have been doing it for years, but its sometimes hit or miss. My feeling is there is too much heat being widely displaced. I would like to direct the heat too a finer area. I have attached some pics of our set up, and an example of with pinch.
