0453955002 - Handheld Nozzle Gas Flow Tester

Stop Guessing, Start Welding with Confidence

Have you ever set your regulator to 30 CFH but still ended up with porosity in your weld? The problem might not be your settings—it could be a leak in your hose, a kink in your cable, or a clogged diffuser. The ESAB Gas Flow Meter (often called a 'peashooter') is the quickest, cheapest insurance you can buy for your welds. It tells you exactly how much shielding gas is actually coming out of your torch, which is the only place it really matters.

Using this tool is incredibly simple. Just place the rubber opening over your MIG or TIG nozzle, trigger the gas (with the wire feed off), and watch the ball rise. The scale gives you an instant, accurate reading of your gas flow. If your regulator says 35 but this tester says 15, you know you have a leak or a blockage somewhere in your line. This simple check can save you hours of grinding out bad welds and re-welding, not to mention the frustration of troubleshooting a machine that seems to be 'acting up.'

This flow meter is built to handle the shop environment. It works with all common shielding gases like Argon and CO2 mixtures. Whether you are a hobbyist trying to get the perfect bead or a professional welder ensuring your setup is dialed in, this tool is a must-have for your toolbox. It also helps you save money; by knowing your true flow, you can dial back your regulator to the exact amount needed, stopping you from wasting expensive gas on every trigger pull.
