pt250ex vs pp256

As I have told others, that's not what I consider ideal.
The problem is that the coupling and uncoupling of the lines leads to condensation in the mouths of the fittings, introducing moisture to the system. A static situation where valves are used is the best.

It does not solve the changing out torch issue.

I see where it could get a little condensation under some circumstances but so far I haven't noticed anything. I'm never in a hurry since welding is just a hobby for me, but if I were in a hurry I believe I could change torches and hoses in about 40 seconds.
Thanks for the opinion. I like to hear what others think, good bad or indifferent especially from professionals.

The way you have the argon flowing through the water trap it is possible to pick up moisture in that bowl. I've heard of other guys making a manifold with ball valves which will work fine. The way I have my 256 set up is the cats ### IMHO. I bought a Miniature Diverting 3-Port PVC Ball Valve from McMaster-Carr. Part number 4757K57 for the valve with 1/4" barbed fittings and part number 4757K58 for the valve with 3/8" barbed fittings. Get the size that matches your welders hose size. I'll take a picture of mine tomorrow and post. It literally takes as long as a torch change to go from welding to cutting WITH ZERO MOISTURE! I may make a video displaying how fast one can from one mode to the next with this setup.
