Excuse me if this is a dumb question. I just purchased a Lincoln 140T and loaded it up with .035 wire flux-cored wire. I am wondering, if I want to switch between wire sizes or types (eg for gas welding), what is the best way to remove the 6' or so length of wire already in the gun hose? Do you just pull it back out from the machine side and coil it up on the spool and then changes spools. I checked my manual 10 times and can't see where this is covered--lots covering the initial loading of wire, but nothing on removing existing wire from the hose?? Thanks in advance.
