Frequently Asked Questions
1.0 We see and hear that there are other thoria-free 'ecological' tungstens available at lower prices than MultiStrikes®?
The MultiStrike® trademark has become an international industry standard.
When buying MultiStrike®, you are purchasing a consistent, guaranteed, reliable, traceable product which will not vary and let you down in production.
Many cheaper tungstens may have unreliable sources.
The MultiStrike® tip colour is known as 'House Blue', immediately distinguishable from any other tungsten and is part of the Trademark of Huntingdon Fusion Technqiues HFT®.
2.0 My latest order of MultiStrike® are not in their usual package, rather in a blue plastic tray with a clear top.
These are NOT MultiStrike®. Please notify us of the name of your Distributor and we will try to rectify the problem and send you correctly packaged MultiStrike®.
3.0 What is in MultiStrike® to make them so good?
MultiStrike® contain a blend of rare earth dopants to replace Thoria. Our dopants are not radioactive and they are mixed in accurate proportions using statistical proportional control procedures, fully computerised to ensure that the tungstens are made to the same high standards every time.
4.0 Will you tell me what materials you use inside MultiStrike®?
The exact ingredients of MultiStrike® are part of our intellectual property gained by extensive research and development to bring a quality product to the market place that is totally traceable, reliable and repeatable.
5.0 I have tried MultiStrike® but they make my welds dirty.
Tungsten electrodes are used to generate an arc. They cannot make a weld dirty. Dirty welds are produced by either insufficient gas coverage, disturbance of the gas flow or dirty and contaminated material being welded.
6.0 I tried MultiStrike® but I got tungsten inclusion in the weld.
Tungsten inclusions can be generated by poor grinding techniques or accidental dipping of a tungsten electrode into the weld pool. Tungsten inclusions can be obtained when using any kind of tungsten electrode. To achieve better grinding, accurately and repeatedly everytime, try our Techweld® Tungsten Electrode Grinders Model TEG-3.
7.0 You said I would get 10 times more arc strikes than a thoriated tungsten, but mine only lasted two welds before I had to re-grind it.
MultiStrike® will give ten times better performance than thoriated tungstens under identical conditions.
Welding conditions will affect the life of all tungsten electrodes equally.
However if a thoriated tungsten electrode is put onto an automatic machine welding with clean components and it gives 20 arc strikes before it fails, then a MultiStrike® will give 200 arc strikes.
8.0 Can MultiStrike® be used to weld aluminium with AC welding?
Yes, MultiStrike® are used widely and successfully for welding aluminium
9.0 I'm worried about the dust generated when I grind MultiStrike®.
Because MultiStrike® do not contain thoria or any other radiotoxic materials, the dust generated is not carcinogenic. Any local Health and Safety standards about the generation and collection of dust should be observed however. For such cases, Huntingdon Fusion Techniques Limited supplies a unique Tungsten Electrode Grinder with a vacuum dust collection facility, designated TEG-3.
10.0 Is there a classification for MultiStrike® as with most other electrodes?
MultiStrike® conform to Standards EN 26848 and ANSI/AWS A5 12m-98
