Easy to install and works great! The gas hose is a bit short, so route it correctly so that it reaches the connector. Otherwise there are no complaints. This replacement saved my welder from falling in the trash.
The trigger does not use a micro switch to turn on the coil. It has a spade connector embedded in a plastic mount, and the trigger bends a piece of metal to touch it. There seems to be a short circuit from time to time and the circuit breaker trips when the trigger is released.
Received and connected the welding gun today. The installation was fine. The gas hose is short. The gun itself is a bit long I think but ok. There is a long piece of metal inside the gun that makes contact with a small pressure fitting that I think is cheap but works. Overall the gun is good and works well.
