Well my welding gases are all empty and I am not prepared to be ripped off anymore by BOG. So I am thinking about going with one of those buy the bottle and then pay a fee and swap for a full bottle. Then when its no longer needed you get your money back when the bottles are returned. Sounds like a better deal but Bunnings only keep D size cylinders (not big enough), other company's like Gasweld have a full range of sizes but they don't keep acetylene. I know I can set it up to use LPG but I don't think it burns hot enough to weld. I would eventually like to have a argoshield 50 or similar for my Mig welder and also oxy and acet for welding and heating. I still have about half a bottle on argon for welding aluminium but I rarely use it, so hopefully it will last for a while.
Over the years people ask can you do a bit of welding on a trailer or broken gate and you just do it for them and never charge for it, but it's getting to a stage now where the money you have to pay to have and use these tools will make the free job a thing of the past.
So who has the best price for this type of gas supply, has anyone on this forum gone down this route and are there any pit falls I need to look out for.
