The coating of electrode is conducted by extrusion press in which the flux briquettes are fed through a cylinder under pressure. While the wire is fed into the wire magazine of the electrode press the briquettes are introduced into the extrusion cylinder of the press. During operation the core wire is fed one by one and coated with the flux by the way of nozzle system in the die box incorporated in the extrusion press. In welding electrode plant extruder is the main machine.
