I've heard that MAG is Metallic (I like metallic over metal) Active Gas welding. This will sound stupid but doesn't welding in an active gas defeat the entire idea of what your trying to accomplish in welding? That is to make welds strong and, of coarse more importantly, sparkly. Does it have something to do with something the parent already contains? I can only think you could use it to perhaps burn off ?carbon? in the metal, like on casts and things. Would you be welding in something like oxygen for this? I can't seem to find any information on this at all, anyone know as to where there might be some? I'm just curious as to what it is.

Thanks very much for any help and merry welding to all,
John
