CONTACT NOZZLE FOR WELDING

The nozzle is used in semiautomatic and automatic welding. It is reliable, cheap, has improved switching and ensures current supply of welding current to the welding arc, feeds both hard and soft electrode wires and cleans them from oxides. The nozzle has cylindrical contact hole (1), and perpendicu...

Zusammenfassung:	The nozzle is used in semiautomatic and automatic welding. It is reliable, cheap, has improved switching and ensures current supply of welding current to the welding arc, feeds both hard and soft electrode wires and cleans them from oxides. The nozzle has cylindrical contact hole (1), and perpendicularly to it a one-way lateral aperture (2) is machined in which a pressing component (3) is mounted pressed by spring (4). The pressing component (3) is dielectric, having shell-like form. Spring (4) is mounted in a peripheral groove (5) of the contact nozzle.
