Purge and Shield with Digital Control....!

High gas flows can pull air into the arc, often causing porosity in the weld. Accurate flow measurement must be used for all gas shielding and purging flows both for technical and economic reasons. Excessive gas flow rates cause turbulence and aspiration of air into the weld area. Precise control of purge and shield gas flow rate is now possible with the Argweld® Digital Flow Meter!

Gas flow rate must be selected with care" and "it is not productive or economical to use more gas than necessary to achieve good shielding. The Argweld® Digital Gas Flow Meter can eliminate argon waste by giving the control of gas usage into the hands of management and the user.

Gas Flow Rate with Extra Care

Purge and Shield Digital Gas Flow Meter

Various gas bodies and several AWS standards make the points that stable and precise gas flow is an important factor in obtaining a good weld.

Gas flow rate must be selected with care and it is not productive or economical to use more gas than necessary to achieve good shielding.

High gas flows can pull air into the arc often causing porosity in the weld.

AWS standards write along the lines that:

Accurate flow measurement must be used for all gas shielding and purging flows both for technical and economic reasons.

Excessive gas flow rates cause turbulence and aspiration of air into the weld area.

The Argweld® Digital Flow Meter shows a flow rate that is easy to read and precise.

It is very accurate, with each instrument calibrated against an international standard, within 1 digit. This calibration sets the system computer to display the exact correct flow number regardless of inconsistencies in the components.

Any gas can be monitored with the Argweld® Digital Flow Meter by using the proper factor based on the mass of the gas.

Stable and Precise Gas Flow 

Purge and Shield Digital Gas Flow Meter

Precise control of purge and shield gas flow rate is now possible with the Argweld® Digital Flow Meter.

The welding Engineer can set his parameters from the outset knowing that operators are unable to alter the settings.

Studies show that welders will set their flow rates higher than needed and waste almost 40% of their shielding or purging gas. This means that the welding engineer together with his management colleagues can demonstrate dramatic yearly financial savings by using an Argweld® Digital Gas Flow Meter.

One reason for the waste of expensive inert gas is the ball in the tube flowmeter. This means of setting flow rates invites careless settings. The operator may not be certain how to set the flow rate, at the top or the bottom of the middle of the ball? (See fig.1). The operator may also be uncertain whether to wait until the ball stops bouncing or just to guess at a point.

The Argweld® Digital Flow Meter can eliminate argon waste by giving the control of gas usage into the hands of management.

Welders are often therefore uncertain how to set the gas flow rate, so they mostly set the rate much higher than necessary. Such flow rates may not be checked and can lead to significant unnecessary gas usage.

With the Argweld® Digital Flow Meter in line, management now has control and will see substantial gas savings from each meter installed.

The new patented Argweld® Digital Flow Meter has a large digital display of the exact flow rate value.

This number can be read from a distance of up to 40 feet (12.2 meter).

Set the Flow Meter as shown and expect to have a flow of 25 CFH, you will be wrong. You will actually get 30 CFH and be wasting 20% of your argon.

Frequently Asked Questions

Purge and Shield Digital Gas Flow Meter

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

The Argweld® PurgEye® 100 IP65 is intended primarily for measuring oxygen levels down to 100 parts per million (ppm) when welding stainless steels and other reactive metals to prevent coking, oxidation and discoloration.

For accurate measurements below this, all of the other PurgEye® Weld Purge Monitors measure accurately down to 10 ppm.

2.0 Is the Argweld® PurgEye® 100 IP65 good enough for electro-polished stainless steel welding?

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

Argweld® PurgEye® 100 IP65 Weld Purge Monitors® show when oxygen has been removed to a level of 100 ppm and that there are no leaks or that there is no outgassing to cause oxygen to remain in the vicinity of a weld.

3.0 Why should I use a Weld Purge Monitor®?

Materials such as stainless steels and reactive alloys will oxidise and discolour when welded in the presence of oxygen.

The Argweld® PurgEye® 100 IP65 will measure oxygen levels as they are reduced by weld purging techniques so that you can begin welding once the risk of oxidation, coking and discolouration has been minimised.

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

A newly designed, self calibrating electrochemical sensor is fitted. 

5.0 How are even lower oxygen levels measured?

HFT® manufactures a 'Family' Range of Weld Purge Monitors® that are suitable to measure oxygen to 10 ppm.

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

The new Argweld® PurgEye® 100 IP65 Weld Purge Monitor® has an auto push button self calibrating facility that calibrates the sensor at both atmospheric and minimum oxygen levels.

This feature allows the sensor to be highly accurately calibrated for each reading throughout the life of the sensor.

In the event that certification is nevertheless required, HFT® has calibration centres around the world.

For the fastest and most economic method to obtain a new certificate, please contact us or your local distributor.

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

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

Please contact us for information about exhaust purge gas cooling methods.
