OT British wiring

Does anyone know the wiring color for Brit electrical circuits ??? I'm looking at a mig welder built over there [SIP Autoweld 160 ]..Figured out the green with yellow tracer is ground...Then I have a brown wire and a blue wire...Which is neutral or power ??? Both wires go to the on-off switch next to another...Does it make a difference?? The money is really right..But , I don't want to burn the circuit board out experimenting..Thanks , Roy

It almost certainly is 220 volts. Our 240 volts probably will be OK for the machine. If any doubts, a buck-boost transformer could be used to get the voltage nearer to 220. 240 volts has no neutral.

Hey ,thanks ...I wasn't sure..Roy

In Germany, green/yellow is ground, blue is neutral and brown or black is power. Sounds like 230 volts. It's a 50hz system here and I thing 60 in the States, does that make a difference?

Done for simplicity and colour blind people as well. In art, blue is a cold colour - so it is here. Browns are a warm colour and that is what it is here. Simple system. European actually. Much beter than red and black for us colour-blind individuals (and colour-blindness is quite common). No mistaking the earth either!

europe is all 220 as far as i know, there wont be a neutral , 2 lives and 1 ground

I'm pretty sure that it will be on 50 Hz rather than our 60 Hz. I don't know if that's a problem with a welder, but I'd hazard a guess that it IS.
I don't know what wire colors are shat but I'd probably take an ohm meter and try each wire to the frame/case and see which one makes contact.

I had forgotten about the 50Hz. Most likely the frequency increase to 60Hz will not cause a problem. The inductive reactance of the windings will be higher at the higher frequency. That may offset the higher USA voltage. The wire feed motor is adjustable speed anyway. I suspect that it will work fine.

Actually it is European wiring codes you have. Green/Yellow is earth
Brown is live.
Blue is neutral. It is 220min to 240max volt 50hz.

The British wiring is
Green is earth.
Red is live.
Black is neutral.
These codes were done away with when we joined the EEC in the early 1970s. I since moved to NZ.

I had an SIP once- they have a design problem with the circuit board- you can't get them to feed the wire properly. Google it- I found enough info to figure out that it probably couldn't be repaired properly. If you haven't already bought it, don't.
