TOHCan: I'm going to stick with the TIG. I did it for a living for about ten years. I don't know if you're familiar with the product, but I welded metal hose; VERY thin material, I'm extremely comfortable with the process. Thank you for the advice on warpage prevention. It was not a big issue in the work I did, but certainly something I need to be aware of. I appreciate the pointers. Funny you mentioned cutting some sheet metal into strips and butt welding them. Back then, that was one of my tests for prospective employees who claimed TIG experience.
I worked with one guy who claimed that a good TIG welder could weld the foil in cigarette packs. Great machines if you get the right one.
Not knowing your experience, I may have laid the patience thing on a bit heavy but better too slow than too fast. Sounds like you have things in hand but if you have any questions I'll try and help out!
I like the cigarette foil quote!
I don't think you laid the patience thing on heavy at all. I appreciate you taking the time to share your experience with a newcomer.
