Description

one

This invention relates to ycTpoftiCTiBa M for electric welding.

From electrodes for the removal of slag for various types of electric avarks containing electromolTs and electromubes are known.

Indicated devices contain strikers, electromagnetic coils and. the system was controlled by their power supply from a single-phase network of alternating current (AC). The load was supplied with core glue, which destroy the glass of the x-ray slug.

The disadvantage of devices is that it is inconvenient in operation, due to the need for transferring connecting connecting devices, the length of which must be no less than the distance from the place of avark to the nearest power source. When welding works are completed, this distance averages 25–30 m, and in terms of the type of building conditioner, 50–70 m.

The goal of the proposed and 30 breaching is to increase usability.

For this, one common output of electromagnet coils is provided with a removable contactor, made in the form of a thread rod with a thread and an anchor pin, with a protrusion on which a fixed M1 pin is mounted and electrically insulated, and the contact surface

the rod is pushed out of the gab.arryth magni.ta.

FIG. 1 shows a diagram of the device; in fig. 2 scheme of using ycTpo CTiBa.

The device contains a coil forward 1 and reverse. 2, the head 3, the control unit 4 of the coil feed and a removable contact consisting of a conductive rod 5 with a thread on one face and a contact pin.

a stand on the other, permanent magnet 6, ignored from the rod 5 by dielectric strips 1 -9, conductive washers 10 s tip, infrared | 0m for sealing the wire connected to the coils 1, 2, and nuts

1.1. The magnet 6 is mounted on the rod 5 so that the contact surface of the rod 5 is outside the limits of the magnet. 6. Unit 4 is provided with a single-conductor input with terminal 12 and switch 13.

The device is connected to the power source 14 of the welding arc |, turns on when the arc is broken and, accordingly, cut the idle speed of the power source.

To connect to power sources

The water unit 4 is connected to the welding cable 1 M 14 by terminal 12 near the holder. 15 aviation materials, and a removable contact rod 5 is mounted on the welded product 16 connected to the power source. At the same time, the matnit 6 holds the rod 5 on the P01 supernova) and the product 16 to be welded, allowing the drying contact surface of the rod 5 to be pressed to the product 16. The gaskets 7–9 exclude the possibility of switching on the magnet in the coil power supply circuit. controlled by block 4, the firing pin 3 is driven. Subject and v. b ip e t iH and a device for ovarn, containing a head, a coil and a power supply control unit from a single-phase network, characterized in that, in order to improve the performance of the device, one common vivod of coils is fitted to an integrated one the product is removed by a contact made in the V1 type of a conductive rod with a contact-contact protrusion on which an permanent magnet is electrically isolated.
