is directed to the tube b, then the tube 6 is not locked and can 6jjTb can be removed from the housing 7 after turning it 90 counterclockwise.

In a right-angled protrusion 23 of the cheek 5 of the handle 3, a cylindrical hole | 3 | aperture 24 is made, in which the final path 13 is placed (see FIG. 4). The guide path 13 is fixed in the hole 24 with a figured pin 25f having two positions: Open and Closed (see Fig. 5).

In the case of closure, the cutout 26 of the pin 25 (see Fig. 7) is closed in the opposite direction from the path 13, and the figured pin 25 enters the groove 27 of the path 13 and stops the path 13 (see Fig; 4.7). In the open position), the cutout 26 of the pin 25 is directed to the groove 27 on the path 13, providing a removable connection of the directing path 13 with the housing 7

The gas and gas supply lines for communication 12 (see Fig. 4) contain a current supply - look for wire 28, control wires 1 for the gas supply pipe ZO (see Fig. 7}. Current supply wire 28 is attached to the housing 7 and the hole 31 is double with 32 screws «Control wires 29 are connected with a two-pin connector 33 installed on the switch block 14, the gas supply pipe 30 is attached to the gas supply pipe 6 with noMot (9-5 nipples 34.

For the connection of the right cheek 5 and the left 4. on the right cheek 5 (in its front part) there is a tapered groove 35, and on the left cheek 4 there is a conical protrusion 36 (see Fig. 2),

The fixing of both cheeks 4 and 5 is carried out. with a screw 37 located in the hole 24 of the protrusion 23 of the right cheek 5, the left end of the BBHiS4HBaioT in the nut 38, fixed rigidly in the left cheek 4 of the handle 3 (see Fig. 8).

At the ends of the handle 3 (see Fig. 2) there is an opening 39 for connection, a gas supply pipe b to the housing 7 on one side of the handle, and an opening 40 for current-supplying commanders Yankadiy 12 on the other side of the handle 3, as well as on the same side there is a hole 24 of the guide path 13,

A short spiral 41 is inserted into the housing 7 :: and a spiral 42 is inserted into the guide path 13 (see Fig. 4).

The predetermined orientation of the device parts and the rigidity of the fasteners in the joints provide optimal current conductivity, gas supply and electrode wire feed. In addition, the rigid connection of one cheek with the housing provides an oriented assembly of the handle, which dramatically reduces the auxiliary time during maintenance and repair of the device,

In particular, when disassembling the handle, its -content is held on one of the cheeks with noMombw. crossbar, Pri. in the event of failure of some elements of the housing, the latter is easily released from the handle with the help of 1 pin5 pnrcjsH, and the failed elements are replaced by replaceable ones using a quick-disconnect connection (if it is a gas and gas supply line), or using a figured pin (if it is a guiding path), which was also done using a clamp (if it is a gas supply pipe), the connection of the gas supply pipe to the body is rigid and quick-detachable due to the cracked protrusions and a rotary lock.

The device operates as follows.
