PurgEye® 100’s new features place this monitor at the forefront of weld purge monitoring.

Global Weld Purging Experts Huntingdon Fusion Techniques HFT® have unveiled their updated PurgEye® 100, with new features that place this monitor at the forefront of Weld Purge Monitoring.

Weld Purging requires the removal of oxygen and it is important that welders know exactly when it is safe to start welding to ensure welds remain free from oxidation. This state-of-the-art Weld Purge Monitor® accurately reads down to 100ppm, suitable for welding stainless steel.

Technical Sales Manager Luke Keane said: “We are very excited to be launching our new PurgEye® 100. Guesswork is eliminated with the monitor and welders can know exactly what the oxygen content is before, during and after welding.”

Weld purging is the act of removing, from the vicinity of the joint, oxygen, water vapour and any other gases or vapours that might be harmful to a welding joint. Such gases may combine with the metal to form undesirable compounds that may reduce corrosion resistance or may be instrumental in creating cracks or other structural defects in metals.
