Im trying to weld some intercooler pipe, ive shamfered the edges on both sides and cleaned it and i cant stop it burning a hole through the pipe. Whats the best cup size for this? I managed to start a weld but not happy with the result

I think there needs to be a section specifically for aluminium welding technique, I have a similar problem. I also can't even perform a tack weld between two pieces of aluminium, the arc wants to jump between the two pieces of Ali and I can't heat both pieces equally, the Ali either melts or doesn't get hot enough to create a puddle, if I try to add filler it only sticks to the piece that's hotter. I'm not sure what I'm doing wrong here.
Hi,
Whilst this isn't an ETSFab course, Justin from TFS does good work, this is his intro into TIG Welding, but he also has other on different forms of welding.
