Hi everyone I am fairly new to the forum and have no experience mig welding at all but I have to learn. I have been reading the forum for some time and had my heart set on a Portamig but unfortunately with today’s financial climate it was out of reach. I have today bought a used Castomag 180 which when I researched it gives results of being a quality machine. I intend to use it mainly for auto bodywork but it is apparently powerful enough for heavier fabrication if needed, being second-hand and also quite old there is no manual with it so my first question is has anyone got one and could they let me have a copy I will of course bear any expense incurred, secondly has anyone used or had one of these can they give me any feedback or opinions of it hopefully I will be collecting it today I have sourced a supply of rent free argon mix which one should I get 5% or 25% and when that arrives the fun will begin, probably with loads more questions. Many thanks Chris
