鴨頸帶閥門，Tweco® Mini MIG 風格前端

Finally got around to swapping the old neck on my MIG gun and this one's swan curve makes reaching into tight spots way easier. The valve works smoothly and the Tweco-style front end locked in without any fuss. Exactly the right fit for my HTP setup.

Replacing the worn-out front end on my MIG gun took about ten minutes thanks to the pre-installed valve and swan neck design. The threads match perfectly and the gas flow is stable, no leaks at the connection. Only gripe is it's a bit stiff to bend at first, but that loosens up with use.

Installed this on my HTP America replacement gun and the fit was perfect, even though it says it won't work with the OEM gun. The valve has a nice, positive feel when you turn it on and off, which I appreciate during long welding sessions.
