Your Questions Answered

What is the intended application for the Argweld® PurgEye® 100 IP65 Weld Purge Monitor®?

This instrument measures oxygen levels to 100 parts per million (ppm) when welding stainless steel and other reactive metals to prevent oxidation and discolouration. For accurate measurements below this, other PurgEye® monitors are available to measure accurately down to 10 ppm.

Is the Argweld® PurgEye® 100 IP65 suitable enough for stainless steel welding?

Weld Purge Monitors® manufactured and designed by Huntingdon Fusion Techniques HFT® have become the world’s standard for measuring purge gas quality in TIG/GTAW and Plasma/PAW welding of tubes, pipes, tanks, and other enclosed structures.

The PurgEye® 100 IP65 detects oxygen levels down to 100 ppm and offers assurance that no leaks or outgassing cause oxygen to remain near a weld.

Why should I use a Weld Purge Monitor®?

Materials like stainless steel and reactive alloys can oxidize and discolour when welded with oxygen.
The PurgEye® 100 IP65 will measure oxygen levels progressively as they are reduced by weld purging techniques so that welding can commence once the risk of oxidation and discolouration has been minimised.

What sort of sensor is used in the Argweld® PurgEye® 100 IP65?

A specialised and innovative solid-state, self-calibrating design.

How can lower oxygen levels be measured?

HFT® manufactures a range of Weld Purge Monitors® that can measure oxygen levels down to 10 ppm.

My company needs a Calibration Certificate once a year for all instruments. How do I obtain one?

The new PurgEye® 100 IP65 monitor has an auto push-button facility that calibrates the sensor at atmospheric and minimum oxygen levels.

This feature allows the sensor to be highly accurately calibrated for each reading throughout its life. If formal certification is required, HFT® has calibration centres worldwide.

Please contact us or your local HFT® distributor for the fastest and most economical method of obtaining a new certificate.

I must detect oxygen levels in pipes pre-heated to 300ºC (575ºF). Can I use the Argweld® PurgEye® 100 IP65 under these conditions?

The Argweld® PurgEye® 100 IP65 Weld Purge Monitor® should not be exposed to gas at a temperature above 50ºC (122ºF).

Can Weld Purge Monitors® only be used when purging with argon?

The PurgEye® monitors can measure the oxygen level, not only inert gases, within any gas. They can monitor the oxygen level when using inert gases such as argon and helium and other welding gases such as nitrogen and nitrogen/hydrogen mixes.

How does the Push Button Auto Calibration feature work?

The Push Button Auto Calibration feature on the Argweld® PurgEye® 100 IP65 allows users to easily calibrate the monitor at atmospheric levels and the lowest oxygen readings, ensuring increased accuracy and reliability during use.

What accessories come with the Argweld® PurgEye® 100 IP65?

The PurgEye® 100 IP65 is supplied with:

2 x AA batteries
Leak-tight stainless-steel probe for sampling
2 meters of gas sampling hose
Sampling bulb (vacuum pump)
Carry strap for neck or wrist
User instruction booklet
Storage and presentation case
Calibration certificate for Quality Control Procedures and Management Systems

What is the significance of the IP65 rating?

The IP65 rating signifies that the Argweld® PurgEye® 100 IP65 is fully dust-tight and protected against water from a nozzle, ensuring the monitor can withstand harsh environments and maintain accurate readings.

If you have any additional questions or would like to learn more about how the Argweld® PurgEye® 100 IP65 can benefit your business, please contact us or your local HFT® distributor.

CLIENT TESTIMONIALS

"The purge meters are second to none."

"I am a huge fan of Huntingdon products and have talked to others over the years about using them. The purge meters are second to none. I own and use regularly my PurgEye 100 and my PurgEye 300. I think somewhere, I still have my original Argweld® MKV monitor, which sadly no longer powers up. I am a scarce breed because I have 3 degrees and a complete academic understanding of metallurgy, but more importantly, welding science; I also have over 20 years of hands-on experience in welding on drill floors, firing lines, and vessel shops. I quite literally have a passion for old-fashioned welding! Excellent product, guys!"

"One of the best, if not the best, residual oxygen detector instruments on the market."

"I believe the PurgEye to be one of the best if not the best, residual oxygen detector instruments on the market with its digital residual oxygen level LED display readouts measuring as low as 0.01% and its large, user-friendly viewing screen making it easier for me to read. I also believe the PurgEye has great accuracy in residual oxygen, with speedy measurements displayed within seconds. The PurgEye is a far cry from the old school homemade 'use a cigarette lighter' to check purge gas flow system."

"Purge monitors are a necessity."

"I can personally vouch for purge monitors. When working with medium to large-diameter exotic pipework, they can prevent you from having a terrible day! I've only used the older model, which was a godsend. Anyone, from the welder who has had to carry out weld repairs due to root weld oxidation (or coking) on such materials, to the directors facing an expensive bill for re-work and possible tarnished company reputation, to the client with their project now running behind schedule - knows exactly what I mean. Purge monitors are a necessity."
