much faster than those non-radio- active ingredients in MultiStrike®, so much so that MultiStrikes® give at least 10 times more arc strik- ing capacity of other Tungsten Electrodes, when tested under the same conditions.
MultiStrikes® can be used for welding aluminium with the AC process, as well as steels and alloys with the DC process, which allows the welder to have just one type of Tungsten Electrode to weld all materials and reduce the amount of stocks and purchasing requisi- tions.
With most Tungsten Electrodes in use still containing radioac- tive and carcinogenic 2% thorium oxide, MultiStrike® provide the TIG and Plasma welder with a safe and superior alternative.
Each packet comes with a trace- ability number to ensure that companies with a quality control procedure have traceability over another aspect of their joining processes.

Inert Shielding Gas Monitor for Stainless Steel Welding
PurgEye API100 PHO 61C Action Shot-Weld
Inert shielding gas is used to protect high integrity welds from oxygen and water vapour during TIG (GTAW) and Plasma (PAW) welding processes.
When welding tanks, vessels, chambers and pipes, the most cost effective inert gas used for shielding is argon. As argon is heavier than air, it displaces the air containing oxygen and water upwards and out of a vent tube which can be fed to a Weld Purge Monitor®.
This process, called Weld Purging, will ensure oxide free, metallurgi- cally sound welds in critical joints made of stainless steel, titanium and other refractory metals.
During stainless steel welding, the oxygen content must be purged down to a level lower than 100 ppm. Titanium and other sensitive materials may have to be purged down to 20 parts per million to obtain oxide free joints. Measur-
ing the oxygen level in shielding gas is therefore crucial.
The low cost, hand held, battery operated PurgEye® 100, designed and developed by Huntingdon Fusion Techniques HFT® is perfect for obtaining zero colour, oxide free welds in stainless steel, reading accurately from atmos- pheric oxygen level (20.94%), right down to 100 ppm (0.01%).
Davina Urquhart, City College AND Senior Welding Engineer at TransWeld Services Ltd recently said: “I am a huge fan of the Huntingdon products and have talked others over the years into using them. The purge meters are second to none. I own and use regularly my PurgEye® 100 for stainless steels and my PurgEye® 300 for titanium. In fact I think somewhere I still have my original Argweld® MKV monitor from the 1970’s. Excellent product guys!”
The PurgEye® 100 is IP65 rated
