Hi to all, My shroud has started to arc if I run it too close to the metal, it doesn't have to make contact to arc. Also when it arcs it seems to put a pull on the machine.I spray murex anti spatter into the shroud and on the tip.Do I need a new shroud? My welder is a new Portamig SWF 350S with a Binzel Arbicor 36 torch. I have allready typed this post but I lost it somewhere. Thanks for the expert help, Martin.
