Pure Tungsten Electrode ISO 6848 ANSI/AWS A5.12/A5.12M-98
Pure tungsten electrodes are the ones without any addition of oxide. This allows the tip to form a clean, balled end which provides good arc stability on AC. The power of electronic transgression is as high as 4.5ev. Requiring a high voltage for arc derivation, it has a low current capacity and is easily burnt. It’s good for application under the condition of AC and in the situation of low welding requirements.
Parameter Specification
Specification:
1.Dia: 0.5-25mm
2.Length: 150mm, 175mm, 178mm, other length as customer required.

Feature:
It can form a clean, balled tip when heated and provides great arc stability for AC welding with balanced wave. Pure tungsten also provides good arc stability for AC sine wave welding, especially on aluminum and magnesium, but is not typically used for DC welding (it does not provide as strong of arc starts as thoriated or ceriated tungsten electrodes).
Application:
It’s good for application under the condition of AC and in the situation of low welding requirements.
