Since buying this welder s/hand ive replaced:- gas block ,swan neck, gas pipe, shroud,tips, wire, earth lead, earth clamp. It would of been quicker listing the parts i havnt replaced!!!
I'm sorry to hear this but, as I've said before, MIG welders strike me as complex, with too much to go wrong, compared to a simple arc welder. I think the level of enthusiasm - almost hero worship for MIG welders is over-stated. I know this may be a minority opinion but I continue to press on with my arc welder for both thick bars and thin steel sheet.
