Quality Weld Purging is essential when welding metals such as stainless steel, zirconium, nickel alloys and titanium. The area around the weld must be purged of oxygen to as low as 50 parts per million (ppm) before, during and after welding to ensure all joints are metallurgically sound and oxide-free.
To remain at the forefront of Weld Purging Technology, Huntingdon Fusion Techniques HFT® have launched the updated hand-held PurgEye® 200 Weld Purge Monitor® , now with PurgeNet™.
Ron Sewell, Chairman for HFT® said: "The correct use of a Weld Purge Monitor® , designed and calibrated specifically for weld purging, will ensure that all welds remain free from oxidation and metallurgical imperfections."
"The PurgEye® 200 is designed and manufactured with the HFT® revolutionary PurgeNet™, allowing networking to a range of accessories. Typically, one accessory allows direct interface to an Orbital Welder or any other automatic welding machine, 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. A second accessory is an audible and visual warning device that will signal externally when oxygen levels are lower and higher than pre-set levels."
The portable PurgEye® 200 has an OLED (organic light emitting diode) display, which will give brighter, clearer and sharper readings for viewing at greater distances than before and at wider angles. These OLED displays are mainly symbol based rather than text based, making the menus internationally comprehensible.
The PurgEye® 200 operates either from long life rechargeable batteries or mains power. Charging can also be carried out from a dock (optional).
Along with louder, 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 to 10 ppm). The Monitor 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 also records Weld Purging results to provide quality control documents for each weld. The monitor also has the capability to switch between percentage oxygen and parts per million shown on the display.
