Measure your argon for the best weld quality

6th September 2016


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.

Weld Purge Monitors are essential instruments, usually needed to help achieve non-oxidised, zero colour welds when welding metals such as stainless, chrome and duplex steels as well as titanium and nickel alloys.

Few welding personnel realise however that they can use their Weld Purge Monitors to measure the quality of the argon gas being used during weld purging.

A low cost PurgEye 100 Weld Purge Monitor available from Huntingdon Fusion Techniques HFT can quickly ensure the quality of the argon gas being used by measuring from atmospheric level (20.94%), down to as low as 100 parts per million (ppm).

A customer recently said: “More and more in our experience we are finding inferior argon that isn’t what it says on the bottle. Often, customers blame other equipment such as their purging systems or monitors for getting bad heat tint, when in actual fact it could well be their source gas quality.

“This issue can be solved quickly by simply connecting the PurgEye 100 directly to the regulator on the argon cylinder before welding or purging and measuring the ppm level.”

The PurgEye 100 is IP65 rated and comes with leak-tight push buttons, auto calibration features, vacuum-sealed leak-tight probe assembly, wrist/neck strap and tripod mount.

The extra long life sensor provides approximately 18 months life before it requires changing. A low sensor indicator will appear on the screen, warning that a new sensor is required. Once that icon appears, it provides the user with adequate time to obtain a new sensor, which can be fitted like changing a battery and the monitor can be re-calibrated easily by the user.

The PurgEye 100 has a clear, easy to read LCD screen, with a 24 mm high display. The display also shows a low battery icon. When the monitor is not in use, an automatic sleep mode activates to conserve battery life.
