Weld purging techniques are now used in most industries, especially when welding reactive metals. Whilst the welding torch provides a protective cover to the top of the fusion zone, inert gas coverage is also required at the weld root. By sampling the gas and testing the oxygen content around the weld, the welder knows when to start welding for safe results.
The basic-entry level Weld Purge Monitor®, called the PurgEye® Nano, designed and developed by Weld Purging Experts Huntingdon Fusion Techniques HFT®, will show oxygen levels down to 1 ppm (accurate to 10 ppm), which can be used to monitor the oxygen content when welding titanium, zirconium and other reactive metals.
Luke Keane, Technical Sales Manager for HFT said: “Our low cost PurgEye Nano is a no frills monitor, perfect for those with restricted budgets. The monitor is small, lightweight and easy to use.”
The PurgEye Nano has been developed for weld purging where data logging, alarms and machine control are not necessarily required. The monitor has been developed with a unique long-life sensor that has a warm up time under 60 seconds.
With leak-tight connectors for weld purge hoses, the PurgEye Nano can be used with optional accessory hand pump and gas sampling probe. It can be used to check purge gas quality from the main source and at the exhaust end of a purging system, as well as to find air leaks in purging hose connections anywhere in a system. The monitor can also be used to check the quality of the gas source to ensure that no contamination is present.
HFT has a family range of PurgEye Weld Purge Monitors for every application. The range includes hand held, battery operated monitors and mains powered monitors, which can read oxygen levels from atmospheric level of 20.94%, right down to 1 ppm.
Ron Sewell, Chairman for HFT said: “All of Huntingdon Fusion Techniques HFT’s weld purge monitors and inflatable tube, pipe and pipeline weld purging systems as well as our inflatable welding enclosures are manufactured in the UK.”
