Well, After having a chat with Finbarr from Express, because the Lorch was welding differently from the results we had on-site, It was a bad bottle of gas. He knows of people having an issue with stainless, For some reason, especially at winter, the 2% carbon dioxide that should be in the cylinder is a lot less or none at all. After changing the cylinder, the results are amazing. So the Fronius poor results are because of the gas too. Anyway. I will check the forum rules on selling and get it up for sale. Cheers Dave
