Metallurgically sound and oxide-free welds are a minimum requirement now when welding stainless steel, zirconium, nickel alloys and titanium. Quality control procedures are in place within most industries and welders are no longer able to ‘guess’ when their oxygen level is low enough to begin welding.
Oxygen levels as low as 50 parts per million (ppm) are often required when welding these reactive metals, however, the welding industry is no longer able to use old fashioned oxygen analyzers which are unable to reach this level.
The rechargeable, hand held PurgEye® 200 is a Weld Purging Monitor® specifically developed and designed for welding stainless steel, zirconium, nickel alloys and titanium.
Georgia Gascoyne, CEO of Weld Purging Experts Huntingdon Fusion Techniques HFT® said: “The PurgEye® 200 portable 10 ppm monitor will ensure zero colour, non oxidised welds are achieved every time, with accurate readings down to 10 ppm.”
PurgeNet™, another first from the Manufacturer, allows this and other Weld Purge Monitors® in the Range to be connected to accessories including an automatic welding machine interface so that the oxygen level in the vicinity of the weld can be monitored and the welding machine can be switched on or off according to pre-set oxygen levels. Other accessories include external audible and visual warning devices and a dew point monitor.
The PurgEye® 200 has an OLED (organic light emitting diode) display, which will give bright, clear and sharp readings for viewing at distances and wide angles. These OLED displays are mainly symbol, rather than text based, making the menus internationally comprehensible.
This exceptionally advanced instrument is able to operate from rechargeable batteries or mains power. Along with loud, pre-settable audio alarms for rising or falling oxygen levels, the PurgEye® 200 comes complete with a faster response long life sensor and integral electro-mechanical pump to extract samples from a weld purge zone, in the event that there is insufficient flow rate or positive pressure to activate the sensor correctly.
The PurgEye® 200 Weld Purge Monitor® reads down to 1 ppm (very accurate as far down as 10 ppm). It is IP65 rated, which means it can be used in very demanding areas where instruments are used on site, such as in desert or tropical conditions. PurgeLog™ Software is provided to record Weld Purging results and provides quality control documents for each weld.
