When the copper band 7 made of copper expands outward more than the protrusion tube 3A made of brass by heat generated when it is transferred to (3), the adhesion between the torch head 3 and the copper wire 6 is loose. As a result, current transfer to the torch head 3 side by the copper wire 6 becomes very poor, and high heat is generated in the copper band 7 part due to the current resistance. Accordingly, there is a problem of shortening the service life due to deformation of the torch head 3 and the copper band 7 and premature damage such as the hose 8 and the rubber coated pipe 9.

At the end of the wire), the copper wire 6 is crimped and fixed to the copper band 7 so that current can be transmitted to the torch head 3, and the outside of the copper wire 6 is covered with a rubber sheathed pipe 9 to switch 10 And a lever 11 for operating the switch 10 and the copper wire 6 and the copper band 7 fixed to the end of the torch head 3 by fixing the lead 12. It is.

이와같은 본 고안은 결합된 분할손잡이(1)(1')를 손으로 잡고 레버(11)로 스위치(10)를 작동시켜 호스(8)를 통하여 가스를 공급하면서 동선(6)을 통하여 토치헤드(3)에 전류를 전달되게하여 탄산가스용접을 하게되고 이의 용접방법은 종래의 용접방법과 동일한바, 상기에 있어서 본 고안은 토치헤드(3)의 돌출관(3A)의 끝부분에다 동선(6)과 동밴드(7)를 납(12)용접으로 고정하였기 때문에 전류의 발생열에 의하여 동밴드(7)가 황동으로된 돌출관(3A)보다 크게 팽창되어 돌출관(3A)과 동밴드(7)사이가 조금넓게될 경우에도 돌출관(3A)과 동밴드(7)에 밀착상태의 연성의 납(12)에 의하여 동선(6)의 전류는 토치헤드(3)에 매우 양호하게 전달된다.The present invention has a torch head through the copper wire (6) while supplying gas through the hose (8) by holding the combined handle (1) (1 ') by hand and operating the switch (10) with the lever (11) The electric current is transmitted to (3) to perform carbon dioxide gas welding, and the welding method thereof is the same as that of the conventional welding method. In this regard, the present invention has a copper wire ( 6) and the copper band 7 are fixed by the lead 12 welding, the copper band 7 is expanded more than the brass tube 3A by the heat generated by the current, so that the protrusion tube 3A and the copper band ( 7) Even when the space is slightly wider, the current of the copper wire 6 is very well transmitted to the torch head 3 by the flexible lead 12 in close contact with the protruding pipe 3A and the copper band 7. .

이에따라 전류의 이동저항에 의하여 동밴드(7)부위가 고열로 가열됨으로 인한 손상을 방지할 수 있게되어 탄산가스용접기의 사용수명을 오래연장할 수 있다.Accordingly, it is possible to prevent damage due to heating of the copper band 7 part by high temperature due to the movement resistance of the current, thereby prolonging the service life of the carbon dioxide gas welder.

이와같은 본 고안은 토치헤드(3)의 끝에 고정되는 동선(6)과 동밴드(7)를 납(12)용접으로 고정하였으므로 동밴드(7)가 열에 의하여 조금팽창될때에도 납(12)에 의하여 동선(6)의 전류는 토치헤드(3)에 양호히 전달되어 고열로 가열되는 것이 방지케되어 탄산가스용접기의 사용수명을 오래 연장할 수 있는 효과가 있다.The present invention has fixed the copper wire (6) and the copper band (7) fixed to the end of the torch head (3) by the lead (12) welding, so even when the copper band (7) is slightly expanded by heat to lead 12 As a result, the current of the copper wire 6 is well transmitted to the torch head 3, thereby preventing the heating of the copper wire 6 at a high temperature, thereby prolonging the service life of the carbon dioxide welder.
