(54) ELECTRODE SUPPORT FOR MANUAL ARC WELDING

(57) The invention relates to the welding industry. The purpose of the invention is to ensure electrical safety during welding work by completely eliminating the current transfer to the electrode in the process of its replacement, increasing the reliability of the electrode holder. The current-carrying rod 2 in the clamping area of the electrode is made in the form of a cam 3. Its one side is covered with an electrically insulating material. This embodiment eliminates the effect of current on the welder when changing the electrode, since the electrode is in contact with the insulated part of the power supply rod at the time of removal and installation. 2 Il.

3 is installed in the target hole in the cap 5. After inserting the electrode, the conductive rod with the lower part of the electrode holder rotates 180 ° and fixes the electrode. The electrodes are replaced in reverse order. By turning the rod 80 °, the remainder of the electrode is released and removed.

At the time of installation and removal of the electrode, the voltage applied to it is excluded. The invention relates to welding production and can be used in all parts of the national economy.

The purpose of the invention is to ensure safety during welding operations by disconnecting the supply of current to the electrode during its replacement.

FIG. 1 shows the electrode holder, general view; in fig. 2 - the same section.

The electrode holder consists of a hollow textolite rubberized body, as it is in contact with the insulator 1, inside of which it passes through the emptiness of the current-carrying rod.

Invention Formula electrode insertion hole 6. The elements of the electrode holder are assembled on the current-carrying rod and fixed with the help of a pin 7, which passes through the rotating part of the housing 8. Electrode works as follows. For electrode insertion, the current-carrying 25 Electrode holder for manual arc welding, comprising a cylindrical rotating body with an electrode holding current rod, a twin fork and a protection head, characterized in that, in order to increase safety by disconnecting the current supply to the electrode when it is replaced, the upper part of the current rod in the clamping area of the electrode is made in the form of a cam with a flat the rod 2 with the lower part of the housing 8 is facing the side surface covered with electrical insulation and the insulated side of the camouflage material. fm.1 3 is installed in the target hole in the cap 5. After inserting the electrode, the conductive rod with the lower part of the electrode holder rotates 180 ° and fixes the electrode. The electrodes are replaced in reverse order. By turning the rod 80 °, the remainder of the electrode is released and removed. At the moment of installation and removal of the electrode, the voltage across it is excluded, since it is in contact with the insulated part of the power supply rod. It requires the installation of special equipment for disconnecting the electrode holder from the power source; it is highly reliable in operation.
