It is possible to control the supply state and power of the welding wire and the protective gas supplied to the welding torch 4 from the control box (3a) of the).

However, when performing the welding work on the bottom of the hull or hole tank, etc., using the CO 2 welding machine, when the operator adjusts the welding wire or voltage and current while welding, it moves to the welder main body or feeder. It is inconvenient to adjust, and the wire feeder itself weighs about 15 kg, and when the CO 2 welding wire is installed, the minimum moving weight is about 30 kg. Moving is one factor that slows down work.

The present invention has been made to solve the problems described above, by using a control unit of a simple configuration to enable the gas welder to be used as an arc welder, by moving the wire feeder of the gas welder during operation or separate arc welder The object of the present invention is to provide a control unit for an arc welder, which can eliminate the inconvenience of carrying and can be used with two arc welders by using one gas welder.

In order to achieve the above object, a control unit for an arc welder according to the present invention is connected to a gas welder, and is provided with a power line, a gas line, and a control line. And a voltage adjusting part connected to the connector part to adjust a working voltage. The gas line of the single cable is cut off, and the power line is connected to the arc welder. Can be utilized as an arc welder.

At this time, it is preferable that the control unit further includes a gas blocking unit for blocking the gas line of the single cable.

In addition, it is preferable to further include one input port to which the power line of the single cable is connected and two output ports connected to the arc welder to output the current supplied to the input port to the arc welder.

In addition, it is preferable that a switch unit connected to the connector unit to turn on / off the power of the power line is further provided.

According to an embodiment of the present invention as described above, first, the control line of the single cable connected to the gas welder is adjusted to control the use voltage while the gas line is cut off to utilize the gas welder as an arc welder, the wire of the gas welder There is an advantage to eliminate the inconvenience of moving the feeder or carrying a separate arc welder.

Second, by utilizing a gas welder using a large current as an arc welder using a low current, there is an advantage that can be used as two arc welders using a single gas welder.
