Avoid welding anything with galvanising on it. The zinc fumes are very bad indeed. I always do any welding outdoors, if nothing else it annoys the neighbours, but at least it s well ventilated
You know these comments about zinc and galvanising are so true but it is interesting to note the wider contradictions. We all accept, I am sure the restrictions on welding galvanised material. However I am a carp welder but bought my first MIG set from the welding specialists in Copnor Road Portsmouth in 1995. I was also sold a couple of aerosol cans. This was to be sprayed on the seams and areas to be welded as this helped us rank novices to get better results.
