Choose the proper tungsten electrode in welding projects

Choose the proper tungsten electrode in welding projects.


Tunsten electrodes, be made by materials which has high-melting point, high density, good heat conductivity and electroconductibility,are widely used in many welding objects.Electrodes with different colors on the end, the tungsten element content will be different. When prepare electrodes for welding, some very important factors you should be consider:

First: power (inverter or transformer)

Second: welding material( steel, Alumium or stainless steel)

Third: Thickness of the welding material objects.
