DEVICE FOR MODULE FEEDING OF ELECTRODE WIRE AT LONG DISTANCES

This invention is concerned with a device for feeding of an electrode wire at long distance. This device comprises a pushing module and a pulling module. Near to the pushing module is placed and electrode wire coil. Near to the pulling module is placed a welding burner. The modules are connected with a flexible hose. The pulling module serves as a guide for the pushing module and each module has its own regulator. An electric motor and a mechanical transmission of electrode air are mounted in the guiding module, and a potentiometer for altering the speed of the electrode wire fed in the device is placed on the wire guiding body of the guiding module or of the handle of the welding burner. The guiding module is connected with the other module by an electrical feed-back achieved by the resistance of the electrode wire and the regulator of the guiding module. This regulator is connected by means of electrical connection with the regulator of the other module. Together with the guiding module, these regulators form a common electrical block supplied from the electric current source of the welding device.
