I would like to use this diffuser on another welder I have. Do you know the thread sizes? I am looking for a diffuser that is M9-1.25 going into the gun, M11-1.5 for the nozzle and M6-1.0 for the tip

Asked by: W E Coyote
This nozzle has a 1.5 thread on the nozzle end and a 1.25v thread on the torch end.

Would this be suitable to use with the Eastwood mig spot weld nozzle and what length tip would I use with 0.6 wire. Thanks

Asked by: Steve141
The gas diffuser is standard on our Mig torches. Yes the spot weld nozzle will fit. The contact tips are all the same length. The only difference is for the wire size.
