So now i’m a mig owner again it’s time to sort out some gas. The last time I was welding I bought pub gas and spent a lot of time cleaning spatter so now I want to use argon mix. From what I have read Argoshield light is for up to 4mm but how far can you push that? As sometimes I will want to weld say 8mm. I have been looking at prices and spoke to York factors who quoted a 20l bottle for £207.22 of which £102 is a refundable deposit but they don’t offer a monthly rental option. I think the BOC Volkzone/Hobby deal is ideal for me but I can’t find any mention of it on their website and their price quoted for a Y size are much higher than I have seen people from here say they are paying so is it only available over the phone?
