I have a project that will be best served by sch 40 Alum pipe - in 1" and
1-1/4" sizes. While I do have a tig welder, it is probably undersized for aluminum of this thickness - and its air-cooled. So, what I want to do is stick weld it. Anyone have experience with stick welding Aluminum? What electrodes are best - currents, polarity, etc...TIA,
Tony
