Welding on site can pose difficult challenges, including exposure to extremes of heat and cold, harmful sand and dust and even hazardous fumes. Contamination during welding can lead to loss of corrosion resistance and a reduction in strength so control of oxygen levels is crucial.
With another innovative development, Huntingdon Fusion Techniques HFT® have designed a virtually non-destructible Weld Purge Monitor® to work accurately within extreme environments. The PurgEye® Site is a guarded oxygen monitor in a secure, safe, waterproof and dustproof, tough carry case.
Technical Sales Manager Luke Keane said: “The PurgEye® Site is our on-site monitor, that has been specifically designed for extreme conditions. By using the PurgEye® Site, welders can ensure non-oxidised, zero colour welds are achieved regardless of conditions.”
“With the housing case open, the PurgEye® Site is IP65 rated and IP68 rated with the lid closed. The PurgEye® Site measures oxygen levels very accurately from 1,000 ppm, right down to 10 ppm.”
The PurgEye® Site has a fast response, long life sensor and it is equipped with PurgeNet™, allowing the monitor to connect to a variety of accessories. One of the accessories, an automatic welding machine interface, allows controls to be based upon the oxygen level, to prevent welding if that level is too high. Other accessories include a traffic light visual indication system and a temperature gauge.
The large, bright, OLED display allows the data to be easily read and is mainly symbol based, rather than text. The display does not need a backlight and can be viewed from greater angles than LED screens.
Oxygen levels can be indicated by the PurgEye® Site gas analyser in parts per million (ppm) or percentage, depending on user preference. Flow detection ensures accurate reading of gas samples, along with a blocked filter icon and power on / off with a standby button for sensor warm up.
The small, low volume, almost indestructible case, can be carried anywhere and the PurgEye® Site used either with its internal battery, which lasts up to 10 hours or connected to mains electricity from 90 – 250 v, single phase A.C.
