WE use ESAB 7100 ULTRA in .045 and 1/16" and it is as good as it gets. Liners and consumables last a long time. Our big problems with liners and tips and nozzles comes down to the operator . Liners get bent by welders jerking the feeders around like stubborn dogs. Tips and nozzles go down because they get banged around during cleaning?. Improper amperage and voltage account for the damage not caused by misuse or normal wear. Yes we do have normal wear. Not all of our welders treat the equipment as if if was junk.
