OVERVIEW

Stop Guessing, Start Welding

Are you struggling with porosity in your welds even though your regulator says you have plenty of gas? You might be losing shielding gas before it ever reaches your torch. The ESAB Flow Guard is the simple, pocket-sized solution to one of the most common welding headaches. This "peashooter" style flow meter lets you check exactly how much gas is coming out of your MIG or TIG nozzle, giving you the truth that your regulator might be hiding.

Save Money on Gas

Welding gas is expensive, and wasting it hurts your bottom line. Many welders crank up their regulators just to be safe, blowing through tanks faster than necessary. With the Flow Guard, you can dial in your flow to the exact amount you need—no more, no less. By optimizing your gas usage, this little tool can pay for itself in just a few tank refills. It’s durable enough to toss in your toolbox and simple enough to use in seconds: just press it against your nozzle, pull the trigger, and read the ball height.

Ensure Quality Welds

Consistency is key to great welding. Whether you are in the shop or out in the field, knowing your equipment is performing correctly gives you confidence. The Flow Guard fits over almost any standard MIG nozzle or TIG cup. It measures flow from 5 to 25 liters per minute, making it perfect for everything from light sheet metal work to heavy structural fabrication. Don't let a leaky hose or a faulty regulator ruin your work; verify your flow at the source and weld with confidence.

  • Instant Verification: Checks flow in seconds.
  • Universal Fit: Works with most MIG and TIG torches.
  • Durable Design: Built to survive the shop environment.

FAQ

Place the rubber opening of the Flow Guard over the end of your MIG nozzle or TIG cup to create a seal. Trigger the welding torch (ensure wire feed is disengaged or speed is zero) and hold the device vertical. Read the flow rate where the ball hovers on the scale.

A difference usually indicates a leak in your gas line, a restriction in the hose/liner, or an inaccurate regulator gauge. The Flow Guard shows the actual gas reaching the weld, which is the most important measurement.

Yes, the ESAB Flow Guard is designed to measure common shielding gases including pure Argon, CO2, and Argon/CO2 blends effectively.

The scale is graduated in Liters per Minute (L/min). To convert to Cubic Feet per Hour (CFH), you can roughly multiply the L/min reading by 2.1.

Yes, as long as the ceramic cup fits within or against the rubber seal at the bottom of the tester, it will provide an accurate reading.

It is a diagnostic tool that helps prevent porosity by confirming you have adequate gas coverage. If you have porosity but the Flow Guard shows good flow, the issue may be base metal contamination or wind drafts.

It is made from impact-resistant plastic, but like all precision measuring instruments, it should be stored in its protective sleeve or a safe place in your toolbox to prevent cracking the tube.

No, this is a setup tool. You must stop welding, position the tester, and trigger the gas flow only (without an arc) to take a measurement.
