Looking for any book describing tig copper welding, electrodes, settings, techniques and other info to help an experienced aluminum welder transition to copper materials.

Hi. You are looking for something that is treat as a dark art. We have tried at work using standard kit. tig with standard tungstens and argon back purging. The result was ok. I have heard that using another type of gas that i can not think of the name keeps the heat better on the job. There is an American guy the demonstrates it on you tube i will have a look around and post when i find it.

Have you looked at the Copper Development Association website? There is all sorts of technical information there.

They have a publication search (although the reference I found to 'Modern methods of welding copper' was dated 1943. Modern, I suppose, compared to Modern machine shop practise by Joshua Rose, from 18-something).

I believe the alternative (and original) gas is helium. This gives a hotter weld pool. Hence the original name for TIG, heliarc. Argon is used now as it is way cheaper.
