Weld Purging is the act of removing oxygen from the vicinity of a weld, before, during and after welding reactive metals by displacing the oxygen with an inert gas (usually argon).
When welding stainless steel, the oxygen level must be reduced to a required minimum, which is less than 100 ppm.
The most effective way to know the oxygen level is to measure it with a Weld Purge Monitor®. Leading the way in Weld Purging Monitoring Technology, Huntingdon Fusion Techniques HFT®’s PurgEye® 100 is perfect for obtaining oxide free welds in stainless steel, reading accurately from atmospheric oxygen level (20.94%), right down to 100 ppm (0.01%).
Ron Sewell, Chairman for HFT® said: “It is important not to use alternative low cost oxygen analyzers or other oxygen safety monitors as they are calibrated under ambient conditions and therefore unsuitable for measuring purge levels down to 0.01% as our Award Winning PurgEye® 100 does.”
The PurgEye® 100 is IP65 rated and comes with long life sensor, leak-tight push buttons, auto calibration and a vacuum-sealed leak-tight probe assembly. The monitor has a clear, easy to read LCD screen with features such as a low battery icon as well as the low sensor icon. When the monitor is not in use, an automatic sleep mode activates to conserve battery life.
The Weld Purge Monitor® was invented by HFT® in the 1970s and with over 40 years of innovation, design and manufacturing experience, the company now has a Family of PurgEye® Weld Purge Monitors® to measure oxygen levels from atmospheric content (20.94%) down to 1 ppm (accurate to 10 ppm).
Ron continues: “All of Huntingdon Fusion Techniques HFT®’s Weld Purge Monitors® and Inflatable Tube, Pipe and Pipeline Weld Purging Systems are manufactured in the UK. We do not sacrifice on quality. We guarantee to help you achieve zero colour welds, time and time again."
