I bought some consumables for the torch, the nozzle was looking gnarly but I cleaned it up by putting it in the lathe though, think it will work a while yet. Biggest issue is probably the insulating ring on the back has partially fallen off, but it still works. Anyway when I got the new nozzles I see I have gotten cylindrical nozzles. Not tapered ones, when I double check the place I bought them from has a picture of a tapered nozzle, but it does say cylindrical nozzle. Are these still OK for normal welding using .8mm wire or are they menant for higher power applications and bigger wire sizes?
