15001-20 - Smith 15001-20 MIG Gas Saver Valve 20 SCFH

Save Gas and Improve Starts with the Smith Surge Protector

Every time you pull the trigger on your MIG gun, do you hear a loud "WHOOSH" of gas? That sound is the sound of money leaving your pocket. It’s called a gas surge, and it happens because pressure builds up in your gas hose while you aren't welding. When you start an arc, all that built-up gas blasts out at once. Not only does this waste a tremendous amount of expensive Argon or CO2 mix over the course of a day—especially if you are doing a lot of tack welding or short stitches—but it can actually hurt your weld quality. A massive blast of gas can create turbulence at the weld puddle, pulling in atmospheric air and causing porosity right at the start of your bead.

The Smith 15001-20 Surge Protector is the simple, effective solution to this common problem. It is a small, rugged brass device that screws right onto the back of your welder or wire feeder. You simply attach your gas hose to the back of the surge protector instead of the machine. Once installed, it regulates the flow of gas to a steady, consistent 20 SCFH (provided your regulator is set to 30 PSI). It acts like a traffic cop for your shielding gas, stopping the rush and ensuring a smooth, even flow from the very split second the arc strikes.

This device is incredibly easy to use. There are no knobs to bump or settings to accidentally change. Because the flow is fixed at 20 SCFH—the sweet spot for most standard MIG applications—you get consistent coverage every time. It works with all standard shielding gases, including Argon, CO2, and Helium mixes. If you are looking to lower your shop's consumable costs and get smoother, cleaner arc starts, the Smith Surge Protector is an accessory that pays for itself in tank savings alone.
