본 고안은 와이어피더상에 전원 스위치를 설치한 CO2용접기에 관한 것으로 더욱 상세하게는 CO2용접기 중에서 용접전원 내부에는 와이어피더 모터를 제어하는 제어회로가 없고, 와이어피더 제어용 전원만 구비하고, 와이어피더 몸체에 와이어피더 모터 제어용 제반회로를 포함하는 변압기와 프린터 써키트 보드가 설치되어 있는 CO2용접기에서 CO2용접을 하지 않을 때 용접기 전원을 끄기 위해서는 용접전원에서 스위치를 끄면 전체장비의 전원이 꺼지나, 와이어피더상에서 전원스위치를 끌 경우 와이어피더 내부의 와이어피더 송급 모터 제어회로 전원만 꺼지고 용접전원의 전원은 꺼지지 않기 때문에 용접작업자가 용접전원 전면까지 직접 가서 전원 스위치를 꺼야 하는 불편함을 와이어피더 콘트롤박스상에 구비된 전원 스위치를 끔으로서 와이어피더의 제어전원은 물론 용접전원의 제어전원 스위치도 끄도록 한 것이다.The present invention relates to a CO 2 welding machine provided with a power switch on the wire feeder, and more specifically, there is no control circuit for controlling the wire feeder motor inside the welding power source of the CO 2 welding machine, and only the wire feeder control power source is provided, and the wire pass when the wire on the feeder body is not a feeder motor controlling various circuits CO 2 welding in CO 2 welder with transformer and printer circuit boards are installed, including the order to turn off the welder turned off the power to the entire machine, turn off the switch in a welding power supply If you turn off the power switch on the wire feeder, only the wire feeder motor control circuit power inside the wire feeder is turned off but the welding power is not turned off. Wye by turning off the power switch on the box Control power of the feeder, as well as to a control to turn off also the power switch of the welding power source.

일반적으로 CO2용접기는 제3도에 도시된 바와같이 용접전원(1), 싱글케이블(2), 와이어피더(3), 용접토치(4)로 구성되고, 와이어피더(3)의 와이어피더 모터제어용 회로의 설치위치에 따라 분류하면 용접전원내에 설치된 형과 와이어피더 몸체에 별도의 제어박스를 형성하고 내장시킨 형으로 구분할 수 있다.In general, the CO 2 welder is composed of a welding power source 1, a single cable (2), a wire feeder (3), a welding torch (4), as shown in Figure 3, the wire feeder motor of the wire feeder (3) If it is classified according to the installation position of the control circuit, it can be divided into the type installed in the welding power source and the type in which a separate control box is formed and embedded in the wire feeder body.

상기한 후자의 CO2용접기는 통상 용접전원에서 싱글케이블 컨트롤 케이블을 통하여 교류 110V 전원을 와이어피더까지 와이어피더 전원으로 공급하고 있어 컨트롤 케이블의 피복이 파손되거나 와이어피더 내부의 전원회로의 누전 등이 발생할 경우 용접작업자의 전기적 감전사고가 발생될 수 있으며, 또한 용접장비 사용 중 휴식, 점심시간이나 작업장소 이동을 위한 와이어피더 이동시 싱글 케이블과 와이어피더를 분리한 경우나 용접작업을 종료한 후 용접전원의 제어전원 스위치를 끄고져 할 때는 작업자가 직접 용접전원까지 가서 용접전원의 전면판넬에 부착된 제어전원 스위치를 꺼야 하는 불편한 문제점이 있었다.The latter CO 2 welding machine normally supplies AC 110V power to the wire feeder from the welding power source through the single cable control cable to the wire feeder, causing damage to the control cable or short circuit of the power circuit inside the wire feeder. In this case, the electric shock of the welding worker may occur, and when the wire feeder is moved during the break, lunch break or work place during the use of the welding equipment, the single cable and the wire feeder are separated or the welding power source is terminated after the welding work is completed. When turning off the control power switch, the operator had to go directly to the welding power source and had to turn off the control power switch attached to the front panel of the welding power source.

따라서 본 고안은 상기한 종래의 문제점을 해결하기 위하여 안출한 것으로 고안의 주된 목적은 용접전원의 제어전원 스위치를 끄고져 할 때 작업자가 직접 용접전원까지 가지 않아도 제어전원을 끌 수 있게 한 것이다.Therefore, the present invention has been devised to solve the above-mentioned conventional problems, and the main purpose of the present invention is to turn off the control power source even when the operator does not go directly to the welding power source when turning off the control power switch of the welding power source.

이하 고안의 요지를 첨부된 도면에 연계시켜 그 구성과 작용효과를 상세히 설명하면 다음과 같다.Hereinafter, the configuration and effect of the present invention will be described in detail with reference to the accompanying drawings.

용접전원(1), 싱글케이블(2), 와이어피더(3) 및 용접토치(4)로 구성된 CO2용접기에 있어서 용접전원(1) 내부에 용접기제어 전원용 변압기(T1)의 1차측 전원을 와이어피더(3)상의 전원 스위치(SW1)로서 켜고, 끌 수 있도록 하기 위한 변압기, 정류회로, 릴레이를 설치하고 싱글 케이블(2)에 컨트롤 케이블을 설치한 구조이다.In a CO 2 welding machine composed of a welding power source (1), a single cable (2), a wire feeder (3), and a welding torch (4), the primary side power source of the transformer (T1) for welding machine control power supply is connected inside the welding power source (1). As a power switch SW1 on the feeder 3, a transformer, a rectifier circuit, and a relay for turning on and off are installed, and a control cable is installed on the single cable 2.

그리고 정전압, 정전류겸용 용접기도 상기한 구조로 와이어피더상에서 전원 스위치로 켜고 끌 수 있는 것이다.The constant voltage and constant current welding machine can also be turned on and off with a power switch on the wire feeder.

이와 같이 된 본 고안은 제1도의 (a)에 도시된 회로도에서와 같이 용접전원(1)내부의 기존 제어전원용 변압기(T1)의 1차측에 릴레이(CR1)를 설치하고 릴레이(CR1) 전단의 1차측 전원에 결선되고 2차측 전압은 24V로 되는 변압기(T2)를 추가로 설치하고 변압기(T2)의 2차측에는 정류회로를 설치하여 교류 25V를 직류 24V회로로 정류하고 정류회로 후단에 변압기(T1) 1차측에 설치한 릴레이(CR1) 전원부와 결선하고 직류 24V회로는 싱글 케이블(2)의 컨트롤 케이블과 결합되어 싱글 케이블(2)을 거쳐 와이어피더 전원 스위치(SW1)과 연결되도록 하고, 작업자가 용접전원(1)의 제어전원과 와이어피더(3)의 제어전원을 끄고자 할때 와이어피더(3)의 전원 스위치(SW1)만 끄면 용접전원(1)의 제어전원용 변압기(T1)의 1차측이 릴레이(CR1)에 의해 차단됨으로 CO2용접기의 모든 제어전원이 차단되는 것이다.The present invention has the relay CR1 installed on the primary side of the existing control power transformer T1 in the welding power source 1 as shown in the circuit diagram shown in FIG. Install additional transformer (T2) which is connected to the primary power and the secondary voltage is 24V, and rectifier circuit is installed on the secondary side of transformer (T2) to rectify AC 25V to 24V DC circuit and the transformer ( T1) Connect the relay (CR1) power unit installed on the primary side, and the DC 24V circuit is connected with the control cable of the single cable (2) to be connected to the wire feeder power switch (SW1) via the single cable (2), When the power supply SW1 of the wire feeder 3 is turned off when the control power supply of the welding power supply 1 and the control power supply of the wire feeder 3 are turned off, 1 of the control power transformer T1 of the welding power supply 1 is turned off. all of the primary side control power to blocked by the relay (CR1) 2 CO welder It will be blocked.

단, 추가로 설치한 변압기(T2)의 1차측만 켜진 상태로 유지된다.However, only the primary side of the additionally installed transformer T2 is kept on.

그리고 제1도의 (b)에 도시된 바와 같이 용접전원부 회로도를 구성할 경우에는 (a)에 설명한 바와 같은 원격 전원 스위치 기능을 발휘할 수 있다.In addition, in the case of constructing the welding power supply circuit diagram as shown in FIG.

그러므로 상기한 구성의 본 고안 CO2용접기는 용접기 1차측 전원이 켜진 상태로 유지되고, 용접전원 전면의 제어 전원 스위치를 켠 상태로 유지되어도 용접전원과 싱글 케이블간의 컨트롤 케이블 컨넥터가 분리되거나 싱글 케이블과 와이어피더간의 컨트롤 케이블이 분리되거나 와이어피더의 전원스위치가 꺼지면 용접전원 내부의 용접기제어 전원용 변압기 1차 전원이 꺼진 상태로 유지되므로 절전효과는 물론 용접전원에서 와이어피더로 공급되는 와이어피더 모터 제어용 교류110V 전원도 꺼진 상태로 유지되므로 용접작업장을 이동하기 위해 싱글 케이블과 와이어피더를 분리하고 싱글 케이블측 컨트롤 케이블 절연상태가 불안정한 상태에서 작업자가 이를 취급하여도 전기 감전사고는 미연에 방지될 수 있는 효과가 있는 것이다.Therefore, the present invention CO 2 welding machine of the above configuration is maintained in the welding machine primary power is turned on, even if the control power switch on the front of the welding power supply is kept on, the control cable connector between the welding power supply and the single cable is separated or When the control cable between the wire feeder is disconnected or the power switch of the wire feeder is turned off, the transformer for the welding machine control power inside the welding power source is kept in the off state. Since the power is kept off, even if the operator disconnects the single cable and wire feeder to move the welding workshop and handles it while the control cable insulation of the single cable is unstable, electric shock can be prevented. It is.
