I notice in the forum that the SIP mig welding sets are not, lets say, the favorite choice. I bought my SIP Autoplus 180 amp mig around 15 - 20 years ago at a cost of around £570 and really can't say that I have had any problems with it, apart from the odd annoying time that it cuts out on overload and I have to leave it for some time to reset. Can members tell me please the downsides to SIP as this is the only mig I have ever used and really dont know any different. Many thanks, Brian (",).
