Weld purge monitors are essential instruments to help obtain non-oxidised, zero colour welds. By measuring the oxygen content before, during and after welding, high quality welds are achieved when welding metals such as stainless, chrome and duplex steels, as well as titanium and nickel alloys.
Huntingdon Fusion Techniques’ (HFT) PurgEye® 100 can help to eliminate the significant post weld cleaning costs that occur when the oxygen level has not been monitored correctly during welding.
Ron Sewell, Chairman of HFT said: “We recently had a European gas turbine manufacturer who was spending a lot of time and money cleaning oxidised stainless steel welds. They were using an unsuitable means to guess the reduction of oxygen.
“They contacted one of our exclusive distributors, who were able to visit them onsite and demonstrate the PurgEye 100. This low cost monitor accurately measures from atmospheric level (20.94%) down to 100 ppm, meaning the welder knows exactly when to commence welding in order to achieve a perfect weld every time.”
The PurgEye 100 is IP65-rated and comes with innovative leak-tight push buttons, auto calibration features, vacuum-sealed leak-tight probe assembly, wrist/neck strap and tripod mount.
The extra long life sensor provides approximately 18 months life before it requires changing. A low sensor indicator will appear on the screen, warning that a new sensor is required. Once that icon appears, it provides the user with adequate time to obtain a new sensor, which can be fitted like changing a battery and the monitor can be re-calibrated easily by the user.
The PurgEye 100 has a clear, easy to read LCD screen, with a 24 mm high display. The display also shows a low battery icon. When the monitor is not in use, an automatic sleep mode activates to conserve battery life.
The HFT weld purge monitor was invented by HFT in the 1970’s. Now, with over 40 years of design and manufacturing experience, the company now has a range of PurgEye weld purge monitors to measure oxygen levels from atmospheric content (20.94%) down to 1 ppm (accurate to 10 ppm).
