H1400-50 - Smith H1400 Series 50 SCFH Fixed Flow Orifice Adaptor

Consistent Shielding Gas Coverage with the Smith H1400-50

Achieving the perfect weld requires more than just a steady hand; it requires consistent shielding gas coverage. The Smith H1400-50 Fixed Flow Adaptor is the ultimate tool for welders who want to "set it and forget it." Designed to lock your gas flow at exactly 50 SCFH, this adaptor eliminates the guesswork and inconsistency often associated with adjustable flowmeters. Whether you are working in a high-production shop or a custom fabrication garage, knowing that your gas flow is constant allows you to focus entirely on the puddle and the arc.

One of the biggest hidden costs in welding is "gas surge" and over-gassing. Adjustable flowmeters can easily be bumped or set too high by operators trying to compensate for wind or drafts, leading to wasted gas and turbulence that actually pulls oxygen into the weld pool. The H1400-50 solves this by providing a fixed, tamper-proof flow. Once installed on your regulator or pipeline drop, it delivers 50 SCFH continuously (provided your system is set to 30 PSI). This not only saves money on gas bottles but also ensures that every weld station in the shop is operating at the same approved specification.

Durability is key in any welding environment, and Smith Equipment delivers with a rugged brass construction that stands up to daily abuse. The adaptor also features a built-in inlet filter. This is a game-changer for longevity, as it stops dirt, dust, and metal shavings from clogging the tiny metering orifice. Without this filter, a small piece of debris could shut down your gas flow mid-weld, causing porosity and rework. With the H1400-50, your equipment is protected, and your uptime is maximized.

Installation is a breeze. The unit comes with standard threads (5/8"-18 UNF and 1/4" NPT) that fit most standard regulators and pipeline outlets. Simply screw it in, set your line pressure to 30 PSIG, and you are ready to weld. It is an ideal upgrade for MIG and TIG setups using Argon or mixed gases, providing the reliability and precision that professional welders demand.
