Still progress to make but I made a step forward today. Changed tungsten electrode to blue tipped (all rounder) and changed the welding rods to make sure I had the right ones for Ali. Also had a chat with the guy about my high gas usage. He told me I was running too much pressure so I also reduced my gas pressure to 6-8 litres per min(?). Low and behold my first try and it worked pretty well. Really happy! Not all good but loads better I now feel I have a good base setting that I can work from.
