PurgEye® 300 Weld Purge Monitor®

PurgEye® 300

Designed and developed specifically for the welding of high specification stainless steels, duplex steels, titanium and other reactive alloys, this is the World’s first purpose designed Weld Purge Monitor®. Small, lightweight and inexpensive, has an indefinite lifespan, measuring from 1000 down to 10 ppm with a large easy to read display.

PurgEye® 300 Weld Purge Monitor

The Argweld® PurgEye® 300 Weld Purge Monitor® has been designed, developed and manufactured by Huntingdon Fusion Techniques (HFT) specifically for the welding of high specification stainless steels, duplex steels, titanium and other reactive alloys.

Most attractively priced instrument reading to oxygen levels for suitable for titanium welding.

Reads from 1000 ppm down to 10 ppm with large alpha numeric display.

HF Proof.

Automatic alarm switching in the event of oxygen level increase.

This lightweight, reasonably priced instrument includes a unique fast response lifetime sensor.

Designed, developed and manufactured to ISO 9000 Quality Standards.

The recording and auditing capabilities of the HFT Family of Weld Purge Monitors® are considered vital to the tube and pipe sector where traceability is now becoming a critical issue and Quality Management print outs are automatically available with our software PurgeLog™ package which is included together with the data connection cable.

The Argweld® PurgEye® 300 Weld Purge Monitor® has been specifically designed for indicating oxygen levels in inert gas for the weld purging of titanium and other reactive alloys where there is a free flow of exhaust gas for measuring purposes.

In the event that insufficient gas flow is available, then see the Argweld® PurgEye 500 Weld Purge Monitor® which incorporates an integral pump.

Argweld® PurgEye® 300 Weld Purge Monitors® are available for immediate delivery.

Frequently Asked Questions

1.0 What sort of sensor is used in the Argweld® PurgEye® 300 Weld Purge Monitor®.

The PurgEye® 300 Weld Purge Monitor® uses a solid state sensor of a unique design. It is very much lower in cost than other monitoring sensors and has an indefinite life span.

2.0 What is the intended application for the Argweld® PurgEye® 300 Weld Purge Monitor®?

The Argweld® PurgEye® 300 Weld Purge Monitor® is intended primarily for welding high quality joints made in titanium, duplex and other high spec stainless steels to prevent coking, oxidation and discolouration.

Where the inlet for the monitor sensor can be connected to a constant flow of exhausting weld purge gas.

When job specification demands accuracy in measuring oxygen levels in weld purge gas from 1000 ppm down to 10 ppm.

3.0 Why isn’t the Argweld® PurgEye® 300 Weld Purge Monitor® fitted with a pump?

Most welding applications have an adequate flow of weld purge gas that can be exhausted over the measuring sensor.

In the event that an adequate flow rate from the system being purged is not available, Huntingdon Fusion Techniques also manufactures a Weld Purge Monitor® with a pump, called the Argweld® PurgEye® 500 Weld Purge Monitor®.

4.0 Why do I need software?

The software package is for those companies who might need to produce a Quality Control document to show that the oxygen level remained below the required value for the duration of the weld.

The software allows the user to plot oxygen reading against time, save the information to hard drive and print the data as required.

Recording and auditing capabilities of the HFT Family of Weld Purge Monitors® are considered vital to the tube and pipe sector where traceability has become a critical issue and Quality Management print outs are automatically available with our software PurgeLog™ package which is included together with the data connection cable.

5.0 Is the Argweld® PurgEye® 300 Weld Purge Monitor® sensitive to electrical disturbances?

Each instrument has shielding to prevent most forms of interference.

Quality Control Test and Inspection criteria are designed to account for as many variables as possible

It is extremely rare that electrical interference will affect the monitor.

6.0 My Company needs a calibration certificate once a year for all instruments. How do I obtain one?

Return the instrument to us, we will re-calibrate it and return it with a Calibration Certificate within a few days.

7.0 I need to detect oxygen level in pipes pre-heated to 300ºC (575ºF). Can I use the Argweld® PurgEye® 300 under these conditions?

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