Characteristic
Pure Tungsten is the longest history of use of a non-melting electrode. it contains tungsten content minimum99.5%, without others impurities .
Pure tungsten electrode is only as welding electrode under the condition of AC or resistance welding electrode , it can clean surface of base matel . Welded ball became tapering when heating . this shape provides a good and balanced wave form for AC welding .
Pure tungsten electrode has a very high electrode output ,low vapor pressure ,low resistance , good conductivity, thermal expansion , high elastic modulus bright .
Therefore, the arc is stable at low current ,and Aluminum, Magesium and other metals can be welded at the current below 5A . But the emission of electron demands high voltage and high no-load voltage of welding machine , The tungsten electrode is burned apparently if it works in the high current for a long time . the end may drop into molten pool after melting,wich will bring the tungsten into the welding gap so ,it's just used for welding some black metal or welding the unimportant parts
