What do you look for when buying mig replacement parts on eBay and on line? I understand that eastwood says that the mig gun parts are TWECO but still that doesn’t help for everything. Like Mig gun liners, Nozzles, Tips and exct. I know Eastwood sells this stuff, Sorry Eastwood, but it can be found cheaper on-line elsewhere. I did fine some Lincoln Tweco Tips at 25-$6.00, either 0.23 or 0.30 and free shipping.
