Tungsten electrode
It is a tungsten electrode made of materials with high melting point, corrosion resistance, high density and good thermal and electrical conductivity. Tungsten electrodes are widely used for welding in their properties. Tungsten electrode grinding or polishing and black rod. The final colors are different, which can distinguish the differences. In tungsten electrodes, more importantly, their final color is different, and their tungsten content is also different. When welding, select the correct tungsten electrode to make welding easier. It is important to obtain high-quality welding. Some important factors to consider in making the right choice are the type of power supply (inverter or transformer), welding material (steel, aluminum or stainless steel) and material thickness.

Applications：
Pure tungsten electrode is most widely used in AC welding; When pure tungsten electrode is heated, the welding ball becomes sharp to provide a balanced waveform AC welding, and the arc is stable; Pure tungsten electrode also provides good arc stability for sine wave AC welding of aluminum and magnesium.
