The PurgEye ® 300 Plus now comes complete with PurgeNet™, which controls all Automatic Welding Systems as well as Orbital Welders, causing them to switch on and off for example when oxygen level rises too high or falls to low.
For control of Automatic Welding Equipment by a Weld Purge Monitor®, the relevant cable accessory will be used. At that point, the Monitor will switch off your automatic welding system if by any chance the oxygen level should rise above your pre-set limit, to prevent the risk of weld oxidation. The Monitor will switch the welding system back on, once the excess oxygen has been purged away.
The IP66 Rated (Environmental Protected) PurgeAlarm™ displays a red indicator, only if the PurgEye® has warmed up, the alarm enabled and is reading a greater value than the alarm threshold set by the user.
An optional green indicator can be fitted above the standard red indicator and will illuminate only if the alarm is active and reading a value lower than the alarm threshold set but the user. A sounder is available as an option to provide an audible alarm instead of the red light.
PurgeNet™ also works with PurgeLog™ to easily transfer weld purge data for Quality Control purposes.
PurgeLog™ software for data acquisition to store and print results and graphs etc for quality management recording and auditing where traceability is vital.

- When job specification demands accuracy in measuring oxygen levels in weld purge gas from 1000 down to 10 parts per million (ppm).
- Also for use with orbital welding machines, with Argweld® Flexible Enclosures® and other purge boxes or chambers.
3.0 Why isn't the Argweld® PurgEye® 300 Plus 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 HFT® also manufactures a Weld Purge Monitor® with a pump, called the Argweld® PurgEye® 500 Weld Purge Monitor® .
4.0 . My Company needs a calibration certificate once a year for all instruments. How do I obtain one?
HFT® has a recalibration facility. Return the instrument to us, we will recalibrate it and return it with a calibration certificate within a few days.
5.0 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.
6.0 Is the Argweld® PurgEye® 300 Plus 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.
