Preventing oxidation when welding tubes and pipes can be achieved by purging the inside with an inert gas. This simple procedure saves both time and cost. By knowing the exact level of oxygen inside the pipe at all times, the welder knows when to start welding for high quality results.
With restricted budgets in mind, the basic-entry level PurgEye® Nano, designed and developed by Weld Purging Experts Huntingdon Fusion Techniques HFT®, will show oxygen levels down to 1 ppm (accurate to 10 ppm), which can be used to monitor the oxygen content when welding titanium, zirconium and all other reactive alloys.
A customer recently said: “The PurgEye® Nano is really easy to use, with excellent results. Previously, each welder would let argon flow as much as possible before starting to weld, to be sure that purging was sufficient. Now, they know when to reduce it prior to welding and in such a way they save good amount of argon. There is no guessing and welders and their assistants can use it after only a few minutes of instruction.”
The PurgEye® Nano has been developed for weld purging where data logging, alarms and machine control are not necessarily required. The monitor has been developed with a unique long life sensor that has a warm up time under 60 seconds.
With leak-tight connectors for weld purge hoses, the lightweight PurgEye® Nano can be used with optional accessory hand pump and gas sampling probe. It can be used to check purge gas quality from the main source and at the exhaust end of a purging system, as well as to find air leaks in purging hose connections anywhere in a system. The monitor can also be used to check the quality of the gas source to ensure that no contamination is present.
HFT® has a Family Range of PurgEye® Weld Purge Monitors® for every application. The range includes hand held, battery operated monitors and mains powered monitors, which can read oxygen levels from atmospheric level of 20.94%, right down to 1 ppm.
Ron Sewell, Chairman for HFT® said: “All of Huntingdon Fusion Techniques HFT®'s Weld Purge Monitors® and Inflatable Tube, Pipe and Pipeline Weld Purging Systems as well as our inflatable welding enclosures are manufactured in the UK. We do not sacrifice on quality. We guarantee to help welders achieve zero colour welds, time and time again.”
As the major international authority on weld purging, Huntingdon Fusion Techniques HFT® provide a very comprehensive technical support system and in addition, they have a Worldwide Exclusive Distributor network which can be found at www.huntingdonfusion.com.
