Return on Investment (ROI)
All Argweld® Pipe Weld Purging Systems and all PurgEye® Weld Purge Monitors® provide instant Return on Investment.
Designed for 'Golden' Welds
The PurgEye® 500 Desk Weld Purge Monitor® has been specifically designed and developed by Huntingdon Fusion Techniques HFT® for the joining of super critical welds where there is insufficient flow of exhaust gas and the integral pump is required.
This model is ideal for critical welds on material such as stainless, duplex and chrome steels, titanium, zirconium, nickel and cobalt alloys. It can be used for joints made in welding chambers and Flexible Welding Enclosures® as well as for orbital welding applications and for use with pipe weld purging systems.
The PurgEye® 500 Desk Weld Purge Monitor® is perfect for ultra critical or 'Golden' welds, where oxygen levels need to be indicated to a very precise level as low as 10 ppm.
In addition, the PurgEye® 500 Desk Weld Purge Monitor® is particularly suitable for welds in ultra clean conditions, such as in LNG, food, semi-conductor, pharmaceutical sectors and any other process industries.
The integral electro-mechanical pump is designed to extract samples from the purge volume at pre-determined, user settable intervals where a strong continous flow of exhaust gas in unavailable.
PurgeLog™ software allows the print out of Quality Management documentation where the recording and auditing capabilities are considered vital to the tube and pipe sector for traceability.
PurgEye® 500 Desk Weld Purge Monitors® are available for immediate delivery.
Incorporating Integral Electro-Mechanical Pump
The PurgEye® 500 Weld Purge Monitor® is small, lightweight and portable.
The automatic fault-finding diagnostics can detect and report a number of possible faults.
The PurgEye® 500 Weld Purge Monitor® has a large alpha numeric display and has a weld start/stop facility.
High and low oxygen levels which can be set on the front panel and the instrument reads from 1000 ppm down to 10 ppm.
The PurgEye® 500 Weld Purge Monitor® incorporates an automatic internal alarm in the event of sudden oxygen level increase, or when the oxygen level reaches the lowest required point. The oxygen levels can be set by the operator.
The integral electro-mechanical pump for extracting a gas sample works automatically where it is not possible to deliver a constant flow of exhaust purge gas over the sensor.
PurgeLog™ software package which is included allows for computer interfacing, data acquisition, storage and printing of results and graphs for Quality Management purposes.
The PurgEye® 500 Weld Purge Monitor® comes with a unique, fast response, long life sensor with little to no maintenance requirement. Special attention has been paid to electrical shielding to avoid interference.
With Electro-Mechanical Integral Pump
The Argweld® PurgEye® 500 Desk Weld Purge Monitor® has a large alpha-numeric display, is menu-driven using four operating buttons on the front panel and has a user interface for external alarm, high/low ppm settings, on/off welding power supply switching and is manufactured to ISO 9000 Quality Standards.
Display readings can be shown in ppm or percentage.
The Argweld® PurgEye® 500 Desk Weld Purge Monitor® has an RS232 serial port for connection to a PC.
PurgeLog™ data logging software requires a PC running Microsoft® Windows and is compatible with the latest version. 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 PurgeLog™.

Frequently Asked Questions
1. What is the intended application for the Argweld® PurgEye® 500 Desk Weld Purge Monitor®?
The PurgEye® 500 Desk is for “in house/in factory use for weld purging of Welding Chambers and Enclosures of all kinds as well as tube and pipe welding production and verification of source gas quality. In house applications demanding extremely accurate readings from 1000 parts per million (ppm) down to 10 ppm, such as welds made in titanium, duplex, nickel alloys and high specification stainless steels. For companies which may need to produce quality control documentation to show which oxygen levels were present during various stages of the welding and post purging cycle. The software allows the user to plot oxygen reading against time, save the information to hard drive and print the data as required.
2. What is the measuring range of the PurgEye® 500 Desk?
The PurgEye® 500 Desk will measure down to 1 ppm and it is highly accurate down to 10 ppm.
3. What sort of sensor is used in the PurgEye® 500 Desk Weld Purge Monitor®?
The PurgEye® 500 Desk Weld Purge Monitor® uses a solid state long life sensor of a unique design. It has a very much faster response time and much greater stability in the readings.
4. My company needs a calibration certificate once a year for all instruments. How do I obtain one?
Huntingdon Fusion Techniques HFT® has several repair and recalibration facilities around the world. Contact us and we’ll refer you to the closest centre.
5. What is the length of the green connecting tube from the PurgEye® 500 Desk Weld Purge Monitor®?
The PurgeEye® 500 Desk Weld Purge Monitor® comes with a 1m green inlet tube with a replaceable filter. The end nearest the filter goes into the green port of the monitor and the other end connects with your purge gas exhaust.
6. Is the PurgEye® 500 Desk 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.
7. I need to detect oxygen level in pipes pre-heated to 300ºC (572ºF). Can I use the Argweld® PurgEye® 500 Desk under these conditions?
The Argweld® Weld Purge Monitor® should not be exposed to gas at a temperature above 50ºC (122ºF). In the event that your purging gases are raised in temperature above this level, HFT® can advise you of ways to cool the gas.
8. What is the integral pump for?
Where there is insufficient flow of the exhausting weld purge gas, the PurgEye® 500 Desk Weld Purge Monitor® with its integral pump will extract the exhausting gas at a precise rate and draw it across the sensor, prior to discharging it to atmosphere.
9. What is an OLED screen?
The OLED (organic light emitting diode) display, will give brighter, clearer and sharper readings for viewing at greater distances and at wider angles than LED displays used by other monitors. These OLED displays are mainly symbol based not text based, which means menus are easily understandable no matter what language the user speaks. The OLED screen does not need a backlight.
