Multi-Strike™ Tungstens Electrodes, a Trade Marked product developed by Huntingdon Fusion Techniques Limited, are high quality premium Tungsten Welding Electrodes for those welding with TIG, GTAW or PAW (Plasma Arc Welding) techniques.

 

Multi-Strike™ Tungsten Electrodes were developed to provide the welder with a safe non radiotoxic/non thoriated tungsten electrode to overcome the health and safety issue related to the storage of radiotoxic materials and the disposal of radiotoxic waste.


The carefully balanced mix of non radiotoxic dopants used in Multi-Strike™ Tungsten Electrodes produces a 10 times greater performance than conventional Thoriated Tungsten Electrodes and a stable performance over the current range from 0 - 300 amps.

 

Multi-Strike™ Tungsten Electrodes represent the highest quality, totally traceable, longest lasting and most reliable Tungsten Electrodes on the Market and allow welding with DC as well as welding of Aluminium with AC techniques giving narrower, lower heat input welds.

 

Multi-Strike™ Tungsten Electrodes are a Fully Traceable Tungsten, the batch number for the tungsten is clearly marked on each packet.

If your Multi-Strike™ Tungsten Electrodes are not in a packet like this, then they are not Multi-Strike™ Tungsten Electrodes!

THE WORK FUNTIONS OF A TUNGSTEN -

 

The work function of a metal or alloy is the energy needed to remove an electron from Fermi level in the material to a point at an infinite distance outside the surface.

 

This is relevant to TIG welding since the lower the work function of an electrode, the lower the voltage necessary to strike an arc.


The work function of tungsten is 4.35 ev. Therefore, the addition of a stable metal oxide with a work function lower than pure tungsten, lowers the work function of the tungsten.

 

Thorium's work function is 3.4 ev

 

Our special blend of dopants has a work function of 2.9 ev.

 

HFT's special blend of dopants along with its stringent in-house production specification ensure that the dopant is distributed evenly through the tungsten maintaining an even performance from start to finish.
