Weld Purge Monitor measures residual oxygen levels.February 25, 2010 -
Argweld® Critical Weld Purge Monitor measures residual oxygen levels as low as 0.001% in inert weld purge gases. Automatic pump extracts gas samples, and device is menu-driven by 2 adjustable buttons. Internal alarm alerts operator if oxygen level rises above preset limit, and system's low-maintenance sensor has 5 yr life expectancy. Monitor can be used and interfaced with all manual and automatic welding techniques.

Argweld® Critical Weld Purge Monitor
Huntingdon Fusion Techniques Ltd has introduced the Argweld® Critical Weld Purge Monitor, specifically designed for measuring residual oxygen levels in inert weld purge gases. It is believed to be the world's first purpose designed and built monitor of this type.
The instrument measures and clearly displays actual oxygen levels as low as 0.001% (10 parts per million).
The unit is menu driven by two adjustable buttons and has an internal alarm to alert an operator if oxygen level rises above a preset limit. A signal can be used to terminate the welding operation should this level be exceeded. An optional software package is available to allow a computer to be used to store and print results for quality control purposes.
A unique new low-cost sensor is used which has a very low maintenance
requirement and an indicated five year life expectancy. An automatic pump is incorporated for extracting gas samples where it is not possible to deliver a constant flow over the sensor.
The Critical Weld Purge Monitor can be used and interfaced with all manual and automatic welding techniques, but will be much appreciated by those engineers requiring sensitive monitoring of low oxygen levels when joining the more reactive materials such as titanium alloys and duplex steels.
