H1400-20 - Smith H1400-20 Fixed Flow Orifice Adaptor 20 SCFH

Set It and Forget It: Consistent Gas Flow Every Time

Tired of guessing your gas flow settings or dealing with broken flowmeters? The Smith H1400-20 Fixed Flow Adaptor is the simplest way to ensure you are getting exactly the shielding gas coverage you need without the hassle of constant adjustments. Designed for welders who want to focus on the arc rather than the regulator, this handy adaptor screws right onto your existing regulator or gas line and locks your flow at a steady 20 SCFH.

We've all seen it happen: someone cranks the gas up to 40 or 50 CFH thinking "more is better," only to cause turbulence that pulls air into the weld puddle, causing porosity. Or maybe the flowmeter ball gets stuck, and you have no idea how much gas you're actually using. The H1400-20 solves these problems instantly. By fixing the flow at 20 SCFH (a perfect standard for many MIG and TIG applications), it prevents gas waste and ensures your weld pool is protected by a calm, consistent stream of shielding gas.

Installation is a breeze. If you have a standard regulator, just unscrew your gas hose, screw this adaptor onto the regulator outlet, and then screw your hose into the adaptor. Set your regulator pressure to 30 PSIG, and you are good to go. The solid brass construction means it can take a beating in the shop, and the built-in filter keeps dirt from clogging the line. It's the perfect upgrade for shops looking to save money on gas bills and welders looking for consistent results.

Whether you are working on a production line or in a custom fab shop, the H1400-20 takes the guesswork out of your setup. No more fiddling with knobs or worrying if the night shift changed your settings. You get 20 SCFH, every time, guaranteed. It's a small tool that makes a big difference in your daily welding operations.
