Mig welding question

[SeanF]

I use Adams Gas which is the same principle as Hobbyweld. I use the 9 litre bottles of 95% Argon 5% CO2 which generally last me 4 - 5 months. I paid a refundable deposit for the first bottle (cant remember how much but something like £50) and its about £38 for each new exchange bottle. I chose Adams because there happened to be a distributor close by. Works very well for me and I would recommend the gas.
