Is me welder a dud?

If you know a friendly publican, brewers Co2 is cheap source of gas for learning, also a Co2 fire extinguisher used upside down because of the dip pipe is another way. Co2 isn’t as nice as argon mix, but works ok, most of us have used it at some time. Just need an appropriate regulator or reg & an adapter.

I agree, for any serious welding, get a bigger bottle.
