Differential pressure gauges are essential tools for monitoring and controlling gas flow during the purging process in orbital and TIG welding. They measure the pressure difference between two points in the purge system, ensuring that the inert gas is flowing at the correct rate to effectively displace oxygen without creating turbulence or wasting gas.
Maintaining optimal pressure is crucial to prevent oxidation and ensure high-quality, contamination-free welds.
We offer two models to suit various purging setups:

• 0–1000 Pa for applications requiring fine pressure sensitivity and precise control.
• 0–3000 Pa for systems with higher flow or larger purge volumes.

Using a differential pressure gauge helps welders achieve consistent, repeatable results by providing clear feedback on purge conditions, making it a vital part of any professional welding setup.
