I am a professional welder employed by a large commercial trucking company with a very high volume work load . We use a spool gun in our shop but one day I came across an unopened bow of aluminum welding rods. I was always curious about aluminum stick so I started using them. I’ve done a few CAT aluminum oil pan cracks and they holding up well . I run the aluminum rods like a 6010 rod with a slight wip and pause motion and it works well for me. Obviously not the best method but you can get good results with practice.

As usual, I most enjoyed the birds. As to the grinder not working without the battery, you might try hooking it to the compressor.

Instead of the flap disk I would recommend a stainless steel wire wheel followed by an acetone wipe. The flap disk can embed oxides in the base material and the wire wheel typically won't. The acetone will get any of the chemical contaminants out. Pre heating should make starting easier. More importantly, it makes your weld act more consistently from start to finish. The material acts quite differently when hot than when cold. Having the material a more consistent temperature allows you to concentrate on your basic technique instead of dealing with the temperature change. Good on ya' for giving it a try! It's a tough weld process for sure.

@DangarMarine

Thanks Brian! I did actually buy some acetone that I left at Adrian's workshop but I'll grab it and put a wire wheel on the grinder too. Someone else was mentioning that maybe even just the heat gun would be enough for the preheating which would be convenient if true. I can see how the preheating would make a big difference as the cold weld is very different to the weld once the job has got warm.
