hi, everyone. i am new to mig welding, i have just bought a second hand clarke welder to try out with. without a bottle. but after reading many of the posts on here it seems as though buying the disposable bottles is very expensive. so i need to upgrade to a bigger bottle, with regulator. my question is, argon. co2. or a mix. but can i use the same regulator with whichever gas i choose? or is their some difference beetween the co2 and the argon gauges? thank`s, in advance. john.
