H1400-30 - Smith Equipment H1400-30 Fixed Flow Orifice Adaptor, 30 SCFH

Optimize Your Shielding Gas with the Smith H1400-30

Take the guesswork out of your welding setup with the Smith Equipment H1400-30 Fixed Flow Adaptor. Designed for professional welders and fabrication shops, this compact device ensures you get a perfect 30 SCFH of shielding gas flow every time you pull the trigger. Whether you are setting up a new station on a shop pipeline or looking to streamline your mobile rig, this adaptor provides a "set it and forget it" solution that guarantees consistency in your gas coverage. No more fiddling with floating balls or worrying if a knob got bumped—just reliable, fixed flow.

The H1400-30 is incredibly versatile and easy to install. It features a standard 5/8"-18 UNF Female thread on the inlet side, which screws directly onto most standard regulator outlets. On the outlet side, a 1/4" NPT Male thread allows you to adapt it to various fittings or solenoid valves depending on your machine's requirements. The unit is calibrated for 30 PSIG input, meaning you simply set your line or cylinder regulator to 30 PSI, and this adaptor handles the rest, metering the gas down to exactly 30 cubic feet per hour. This is the ideal flow rate for many MIG and TIG applications, providing ample coverage without creating turbulence that can pull in atmospheric contaminants.

One of the biggest hidden costs in a welding shop is gas waste. Operators often turn flowmeters up way past what is necessary, thinking "more is better," which actually wastes money and can cause porosity. By installing the Smith H1400-30, you effectively tamper-proof your gas supply. It also features a built-in filter to protect the tiny internal orifice from dust and dirt, ensuring your flow remains smooth and uninterrupted. Backed by the quality reputation of Smith Equipment (a division of Miller Electric), this adaptor is a small investment that pays for itself in gas savings and weld quality assurance.
