It's good to see some licenced sparkies chiming in to this forum with their views. As per above. I use a 40 -140amp stick welder at home off a 15amp circuit. How does that work ???

Stewie ( definiely a non-sparky ) Are you talking about a 15amp circuit breaker or 15amp gpo ? A 15amp circuit breaker is usually a 16amp cb, and 2.5mm twin and earth. A 15A gpo is usually on 4mm twin and earth with a 20A CB. The current output from your welder is at a lower voltage, so the welder is consuming less than 15A on the 240v side. Seen in some USA HT forums, the need for 110v 20A powerpoints for their power amps, where over here the same amp (dual voltage transformers inside) can be plugged straight in to a standard 230v 15A powerpoint.... the lower the voltage needs greater current draw. <standard disclaimer> I am not a sparky !

Re: Electric cable standard - 2.5 mm2 twin & earth cable eno 19May 20, 2015 10:15 am With welders / cutters, the current rating of 40A or 140A is about the current on the output of the welder. This is much higher than the input current. The reason it doesn't draw this much current is that it can use a transformer (or equivalent alternative) to transform the voltage and current. A 10:1 transformer can take 240V at 10A and produce 24V at 100A. In both case it is the same amount of power. So to see if your wiring can handle a device, you need to look at the input power draw, which should be on the labelling. If it has a standard 10A plug, this should be less than 10A.
