Hi everyone I was about to have my first attempt today with my used castomig 180 and noticed that the shroud was bunged up from previous owner who demonstrated it on a hefty bit of steel and laid 2 long runs that looked very impressive and in my ignorance I turned the shroud as if undoing a thread and the result is in the pic I obviously need to replace what I have damaged but I better leave it you more knowledgeable people to tell me what I need and how to do it thanks Chris
