No one says you know nothing mate we just like a friendly debate based on findings and opinions. It's never personal. I agree the subtle changes can be the difference between total success and des aster in Alu mig world. I do a similar job. I take problems on board From companies with consumables and Equipment set up and the theory is to come up with a solution as to generate sales. Sounds to me like you know your stuff people just have different ways of doing things. What works for one guy may not work for another.
