I recently changed the oxygen bottle on my gas welding setup, and felt a significant leak onto the back of my hand from the coupling between the regulator and the oxygen bottle. This turned out to be a fault with the oxygen bottle itself, which was replaced by the supplier. Being a bit hard of hearing, I would not have heard any hiss (even if there was one), and it was lucky I wasn't wearing my welding gloves at the time otherwise I would have been none the wiser about the leak. The question arose in my mind about routine checking for leaks (or at least when changing bottles in the future). My supplier suggested that water could be used, but cautioned against adding washing-up liquid; he did not know of any commercial leak-detecting liquid. Any suggestions? CRB
