Prior to inert gas welding (weld purging), the oxygen content must be reduced (purged) to a level as low as 100 ppm for stainless steels and as low as 50 ppm for zirconium and titanium. When oxygen levels are too high, the parent materials will suffer from a loss of corrosion resistance and metallurgical imperfections.
The innovative PurgEye® Desk, a new monitor designed and manufactured by weld purging experts Huntingdon Fusion Techniques HFT®, is leading the way in inert gas purging technology by reading oxygen levels from 1,000 ppm, right down to levels as low as 1ppm (highly accurate to 10 ppm), ensuring welders achieve perfect oxide free, zero colour welds time and time again.
Ron Sewell, Chairman for HFT® said: “The PurgEye® Desk is for use with Welding Chambers and Enclosures, as well as with Orbital Welding Machines and other Automatic Welding Systems. One huge addition to the PurgEye® Desk is our revolutionary PurgeNet™, for the in-line connection of additional accessories that allows the Weld Purge Monitor® to control welding systems based upon oxygen level as well as to provide indications of high and low oxygen levels and even give dew point measurements.”
The rugged, high frequency proof PurgEye® Desk has automatic fault finding diagnostics that can detect and report a number of possible faults. It also features an OLED (organic light emitting diode) display giving brighter, sharper readings at longer distances.
With a unique, fast response, long-life sensor having little maintenance requirement, the PurgEye® Desk Weld Purge Monitor® comes complete with an integral pump to deliver the exhausting purge gas to the measuring sensor on a consistent basis to allow precision control of the welding systems.
The PurgEye® Desk is particularly suitable for use in ultra clean conditions, such as in cryogenics, food and drinks, semi-conductor, aerospace, pharmaceutical sectors and other process industries.
