Works great, the guy at the welding supplier said it wouldn't work because not a miller, and he heard the 15 foot gun wouldn't work with my millermatic 140 (m10/m100).We replaced it because the machine was arcing inside the machine every few minutes. By the time we cut out the wire and start over it would arc again.It resolved all issues and comes with a shield and tip, ready to weld.It was not easy to install, the o rings were hard (2 people hard) to push in.Once in and sealed no gas leakage at all, tight seal.We almost didn't buy it because another review said it took so long to come in, it took 3 days.
