Pure Tungsten Heavy Metal Electrode

Pure tungsten heavy metal electrodes contain 99.50% tungsten heavy metal, have the highest consumption rate of all electrodes and are typically less expensive than “alloyed” counterparts.

These electrodes form a clean, balled tip when heated and provide good arc stability for AC welding with a balanced waveform. Pure tungsten metal also provides good arc stability for AC sine wave welding, especially on aluminum and magnesium, but is not used for DC welding (it does not provide as strong of arc starts as thoriated or ceriated electrodes).

Pure tungsten heavy metal electrodes Vs other tungsten heavy metal electrodes. Which is better?
Science and technology have lead to greater revelations and drastically changed our lifestyles. Today, you have more powerful systems and appliances including gadgets that enables better efficiency and performance whatever we tend to do using them. It has revolutionized our lives. The newer power source technologies are the more powerful and efficient than the traditional ones that were once used for the same purposes. They give you better precision and perfection of end results. On this context, welding strategies have also been improved with the use of higher quality welding equipments. Today, you have more stronger and sturdy welds being produced and the end products have certainly been very efficient and great. On this note, use of traditional pure tungsten heavy metal electrodes for welding has decreased.

Pure tungsten heavy metal electrode has the ability to melt down at lower temperatures forming rounded ball at the tip of the . This ball as it grows in size during the welding obstructs the welder, not allowing focusing on the task. In fact, it doesn't allow yowelding gunu to see the weld puddle and the arc which is very significant for producing proper welds goes unstable as a result. Predominantly you end up with poor quality welds.

Ceriated tungsten heavy metal electrode on the other hand has tremendous capabilities to work in higher temperatures. It also works pretty well with the modern technologies such as the new square wave and inverters used for providing stability of current supply. It holds the point longer and starts well at low amperages as well. It could be used for both AC as well as DC polarities. It allows welding amperages to be increased by 25-30% when compared to pure tungsten of the same diameter.
