I received my new CK 17 torch set yesterday and guess what? The Miller Syncrowave 250 requires NO adapter to use the CK hose. Thanks to everyone who replied.

My machine is not a 250DX. It is a plain syncrowave 250. If you look at the CK applications, they do not show an adapter for a plain 250. They show 200 series ,250DX, and other 200s but not a 250. Thanks for the reply.

I have been trying to figure out how to adapt the ck flex hose to my Syncrowave 250. The advice received so far is to use a dinse adapter. My machine does not use a dinse style connector. It has a 5/8-18 thread fitting. the ck flex hose has a 3/8 fitting. where can I find a reducer to make this work...
