Hello there, I have little knowledge in the field of physics and respctfully request the more intelligent user to impart some to me. Oxyhydrogen welders. What sort of amps are required to run one? Can they be run on single phase power? Came across one and, probably erroneously, concluded that the required amps must be huge as water is electrolysed, and recombines to form the flame. I realise there are many on the market but they seem to weigh a tonne and require an enormous power supply. Is there a way of running one of these things on household/ single phase power? Much obliged, Ike.
