Hi all, I have just bought a murex 191 and would like to be re-assured that I have not made rash buy.Is this a good welder for car bodywork ( thin rare Japanese) or will it be too powerfull,will it run off a 13 amp supply on lower settings,what size of wire will it take and do you need different drive wheels for each.Any advice would be great,I am still in a state of shock after spending all this money,all the best John.
