Rutile ElectrodeThis type has thicker coating than cellulosic coated and the flux is mainly composed of rutile (titanium di - oxide) and silicates, with a negligible amount of cellulose, but a higher proportion of ferro alloys than in the cellulosic electrode. There is hardly any gas shielding in the arc, but the slag takes care of refining of the weld puddle and strengthening of the weld metal. The slag covers the weld completely and peels off very easily on cooling. The penetration is just sufficient. The electrode, can therefore be used for bridging wide gaps in the joint. The electrode also causes very little undercut, if any. The electrode is easy to use in all positions.
Duty cycle The concept of duty cycle is to be clearly understood before operating any machine. Unlike the arc welding power sources, the resistance welding power sources are de
