The British-made Weld Purge Monitor

A British-made Weld Purge Monitor, said to be technically more advanced than its predecessors and more cost-effective, provides precise indication of the oxygen content of weld purge gas.

The Argweld MKV weld purge monitor, from Huntingdon Fusion Techniques Limited, allows welding to begin as soon as the correct oxygen level is reached, without the need for any estimation or guesswork. It can be used by any industry welding stainless, duplex or chrome steels, as well as nickel alloys. Industries using such materials, and needing to be in absolute control of their “back of weld” quality, include: aerospace, beverage, food, semiconductor, nuclear, automotive, processing, pipeline and petrochemical.

“By showing the operator exactly when the oxygen content is low enough to commence welding, the purge monitor eliminates premature starts, as well as avoiding the waste of time and excessive use of inert gas resulting from any unnecessary delay in starting,” says Darren Sewell for Huntingdon Fusion Techniques.
