Size of welder is start point that gives circit protention size cable size need more info run length and how to be installed supply type etc
Not meaning to hijack, but if say you are not using a welder at high load, can you run it off an extension cord? I have a BOC (magmate 180p) 180A welder but only currently use it at half and less (max of 60-80A)of that capacity. Any reason I couldn't run it off a cord? 240v system here in NZ. cheers

what plugs do u use over there .13 amp here . u can run on an extension lead minimum size cable 2,5mm to avoid voltage drop but would depend on what your plug rating is length of cable also the size of your circuit breaker feeding the socket

you need to work out your maximum potential load and the distance your going to run the cable work out your voltage drop and then that will give you what size SWA you need theres more to it than you think

10 amp here, all extension cables I have seen are rated to 10amp too. Can't tell exactly what my circuit breakers are but they might be 16amp(?) Maybe a short power lead would be alright? Cheers
the type of mcb may have to change most consumer units fitted with standard type 'b'. They are more sensitive and will disconnect quicker and more easily. You may have to fit a type 'c' or even 'd'. Your RCD could trip out unecessarily due to nature of how welder works, it thinks there is a leak to earth. Without knowing the exact details of your supply to house and consumer unit its difficult to be exact.
