New: Unique 10 ppm Colour Touch Screen Weld Purge Monitor® It is essential to monitor the oxygen level when welding reactive metals. Metals that are classed as ‘reactive’ (titanium, zirconium and nickel alloys) are sensitive to oxygen when heated. When welding these metals, the oxygen must be purged from the welding zone, down to as low as 10 parts per million (ppm). Weld Purging in this environment will avoid discolouration of the weld and heat affected zone and limit oxidation that could lead to a loss of metals’ corrosion resistant properties. It will help to guarantee the greatest weld joint strengths and the highest resistance to corrosion. After 42 years of continuous Weld Purge Monitor design, Huntingdon Fusion Techniques HFT® has designed and developed yet another new Weld Purge Monitor® embracing new technological developments. The new style PurgEye® 600 reads from atmospheric level of oxygen (20.94%), down to one part per million (0.0001%) in one instrument, offering big advantages to those manufacturing high specification products made of reactive metals. Georgia Gascoyne, CEO for Huntingdon Fusion Techniques HFT® said: “We are delighted to announce the launch of this new PurgEye® 600 Weld Purge Monitor®.” “Possibly the greatest feature of this new oxygen analyzer, apart from its total measuring range, is our revolutionary PurgeNet™ facility, where accessories such as the dew point monitor, visible and audible alarms, automatic welding machine and other instruments can be connected and triggered by falling or rising oxygen levels.” This state of the art PurgEye® 600 incorporates all of the features and benefits of all the other Weld Purge Monitors® in the HFT® Family Range, but for the first time, this one instrument has a full 8 TUBE NEWS April 2019
