It is characterized in that it can be conveyed through the space part 501 between (5). Although it described as copper wire 8, you may use any of aluminum wire.

이와 같이 된 본 발명은 구리등의 전도체로 된 컨넥터(1)를 전압기등에 꽂아 공간부(5-1)에 배선된 구리선(8)을 통하여 전류를 토치헤드(2)로 흐르게하고 코일스프링(6)이 삽입된 내부호스(4)의 내부를 통하여 용접와이어(7)를 이동시키게되는 것은 종래의 이산화탄소(CO₂)용접기와 동일하다.In the present invention as described above, a connector 1 made of a conductor such as copper is inserted into a voltage lamp, and a current flows to the torch head 2 through a copper wire 8 wired to the space portion 5-1. The welding wire 7 is moved through the inside of the inner hose 4 into which 6) is inserted, which is the same as the conventional carbon dioxide (CO 2) welder.

상기에 있어서 종래에는 가스통(11)의 가스(CO₂)를 용접와이어(7)가 이동되는 컨넥터(1)의 용접와이어안내구멍(1')과 내부호스(4)및 토치헤드(2)의 용접와이어안내구멍(2')으로 흐르게 하였다. 이에따라 용접열에 의하여 토치헤드(2)와 구리선(8)은 높은 온도로 가열케되어 용접작업에 있어 여러가지 지장을 초래하게 되었다.In the above, conventionally, the gas CO2 of the gas cylinder 11 is welded to the welding wire guide hole 1 ', the inner hose 4, and the torch head 2 of the connector 1 to which the welding wire 7 is moved. It was made to flow into the wire guide hole 2 '. As a result, the heat of welding causes the torch head 2 and the copper wire 8 to be heated to a high temperature, which causes various problems in the welding operation.

본 발명은 가스통(11)의 가스(CO₂)를 냉각기(10)에 의하여 냉각시키고 냉각시킨 가스를 가스유입구(101)를 통하여 컨넥터(1)의 가스분배실(1A)로 유입시키게 되면 가스분배실(1A)의 차가운 가스는 가스안내구멍(102)을 통하여 구리선(8)이 배선된 내부호스(4)와 외부호스(5)사이의 공간부(5-1)로 배출되어 토치헤드(2)쪽으로 이동되면서 구리선(8)의 열을 빼앗아 낮추게 된다. 이때 구리선(8)의 사이를 지나는 가스의 이동을 원활하게 하면서 구리선(8)의 냉각효율을 향상시키기 위해선 여러가닥의 구리선(8)의 사이를 느슨한 간격으로 유지시키는 것이 바람직하다. 토치헤드(2)에 도달한 가스는 가스안내구멍(201)으로 유출되어 돌기(203)에 의하여 나선상으로 형성된 나선안내홈(2A)을 따라 나선상으로 흐르면서 토치헤드(2)의 열을 빼앗아 가스배출구멍(202)으로 배출된다. 이에따라 토치헤드(2)및 구리선(8)은 높은온도로 가열되는 것이 방지된다.The present invention is a gas distribution chamber when the gas (CO2) of the gas cylinder 11 is cooled by the cooler 10 and the cooled gas is introduced into the gas distribution chamber 1A of the connector 1 through the gas inlet 101. The cold gas of 1A is discharged through the gas guide hole 102 to the space portion 5-1 between the inner hose 4 and the outer hose 5 to which the copper wire 8 is wired, and the torch head 2 is discharged. As it moves toward, it takes away the heat of the copper wire 8 and lowers it. At this time, in order to improve the cooling efficiency of the copper wire 8 while smoothing the movement of the gas passing through the copper wire 8, it is preferable to maintain the gap between the copper strands 8 of a plurality of strands. The gas reaching the torch head 2 flows into the gas guide hole 201 and flows spirally along the spiral guide groove 2A formed by the protrusion 203 in a spiral manner to take heat from the torch head 2 and discharge the gas. Ejected into the hole 202. As a result, the torch head 2 and the copper wire 8 are prevented from being heated to a high temperature.

이에따라 종래에는 구리선(8)에 비하여 쉽게 절단케되어 사용할 수 없었으나 무게가 가벼워 용접기의 중량을 감소시킬 수 있는 알루미늄선을 사용할 수 있다.Accordingly, in the related art, an aluminum wire which can reduce the weight of the welder due to its light weight can not be easily cut and used compared to the copper wire 8.

설명에서는 가스배출구멍(202)으로 배출되는 가스(CO₂)의 온도가 매우 낮은 것으로 오해하기 쉽게 기재되었으나 가스가 이동하는 동안 구리선(8)과 토치헤드(2)와의 열교환작용에 의하여 가스(CO₂)는 상당한 온도로 가온된 상태에서 가스배출구멍(202)으로 배출된다. 냉각기(10)는 팬에의한 송풍에 의하여 냉각시키는 공냉식이나 물에 의하여 냉각시키는 수냉식중 어느것으로 냉각하여도 좋고 본 발명은 도시된 도면이나 설명에 국한 되는 것이 아니고 요지에 벗어나지 않는 범위내에서 변화시킬 수 있음은 물론이다.In the description, it is easy to misunderstand that the temperature of the gas (CO₂) discharged to the gas discharge hole (202) is very low, but the gas (CO₂) is caused by the heat exchange effect between the copper wire (8) and the torch head (2) while the gas is moving. Is discharged to the gas discharge hole 202 in a state where it is warmed to a considerable temperature. The cooler 10 may be cooled by any of air-cooling or water-cooling by cooling with a fan blower, and the present invention is not limited to the drawings and descriptions shown in the drawings. Of course you can.

이와 같은 본 발명은 구리선(8)을 배선한 내부호스(4)와 외부호스(5)사이의 공간부(5-1)를 통하여 냉각기(10)에 의하여 냉각시킨 가스(CO₂)를 토치헤드(2)로 이동시키게 됨으로 토치헤드(2)와 구리선(8)이 용접열에 의하여 높은 온도로 가열되는 것을 방지할 수 있게되어 용접작업효율을 향상시킬 수 있는 효과가 있다.As described above, the present invention provides a torch head (CO2) cooled by the cooler 10 through the space portion 5-1 between the inner hose 4 and the outer hose 5 in which the copper wire 8 is wired. By moving to 2) it is possible to prevent the torch head (2) and the copper wire (8) is heated to a high temperature by the heat of welding has the effect of improving the welding work efficiency.
