Thanks, I had been told about the importance of removing the oxidation, I was wondering if the rods were exempt and I hadn't even thought about replacing my dirty old tig gloves.By far the biggest thing in welding aluminium is cleanliness. Even if the material is new you must clean it.
The system I use is this:
Wipe the aera with thinners.
Go over the edges with a stainless steel rotory wire brush in a drill. Do this till the area is a matt finish. Any shiny areas will be contamination.
Wipe the weld filler rod with thinners.
Uses new, clean gloves.
Other than that it's just practice.
