Every time you pull the trigger on your MIG gun, do you hear a loud "whoosh" or "hiss" before the arc settles down? That sound is the sound of money leaving your gas tank. 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 again, all that extra gas blasts out at once. Not only does this drain your tank faster—forcing you to swap cylinders more often—but that blast of air can actually mess up your weld start, causing bubbles (porosity) or a stuttering arc.
The Smith 15001-30 Surge Protector is the simplest fix for this problem. It is a small, rugged brass fitting that screws directly onto the back of your welder or wire feeder, right where your gas hose usually connects. Once installed, it acts like a traffic cop for your shielding gas. No matter how much pressure builds up in the hose, this device limits the output to a steady, perfect 30 SCFH. This is the ideal flow rate for most standard MIG applications using Argon, CO2, or mixed gases.
Why you need this in your shop:
Installation takes seconds. Just unscrew your gas hose from the machine, screw the Smith Surge Protector onto the machine's inlet, and then screw your gas hose into the back of the Surge Protector. It uses standard 5/8-18 threads (the standard "B-size" gas fitting used on almost all American welders). It’s a small investment that makes a big difference in your daily welding costs and quality.
