32145 - ESAB Replacement Inner Flow Tube for Argon and Helium

Precision Shielding Gas Control

In high-quality welding applications, the accuracy of your shielding gas flow is paramount. Porosity, oxidation, and erratic arc stability are often traced back to improper gas coverage. The ESAB 32145 Inner Flowmeter Tube is a critical replacement component for welders who demand precision. Designed specifically for Argon and Helium applications, this flow tube allows for the exact metering of gas flow (CFH/LPM), ensuring that your weld zone is perfectly protected from atmospheric contamination.

Technical Accuracy for TIG and MIG

Flowmeters are superior to simple pressure gauges because they measure the actual volume of gas moving to the torch. However, the accuracy of a flowmeter depends entirely on the condition and calibration of the flow tube. The ESAB 32145 is calibrated to the specific specific gravity of Argon and Helium. This ensures that when the ball floats to a specific line, you are delivering that exact amount of gas. This is particularly important in GTAW (TIG) welding of exotic alloys where gas coverage tolerances are tight.

Construction and Compatibility

This inner tube is designed to fit standard ESAB and Victor-style flowmeter bodies. It serves as a direct replacement for damaged or unreadable tubes. Over time, workshop grime, UV exposure, or accidental impact can render a flow tube useless. Replacing it with the 32145 restores the functionality of the regulator assembly without the expense of buying a whole new unit. The tube features clear, indelible graduations that resist fading, allowing for quick setup and verification by welding inspectors.

Installation and Maintenance

Installing the 32145 Inner Flowmeter Tube is a straightforward maintenance task that can be performed in the shop. It integrates seamlessly with the existing outer cover and O-ring seals of your flowmeter. By maintaining clear visibility of your flow rate, you reduce the likelihood of operator error—preventing both the waste of expensive shielding gas (over-flow) and the creation of weld defects (under-flow). Trust in ESAB's manufacturing quality to maintain the integrity of your gas delivery system.
