Since the cables used are placed at a distance of 30 to 5 Qm, the welding power cable 7 is used to guide the power from the welding power source 1 to the welding torch 5. Electric power from the wire feed control circuit 12 built in the welding power source 1 is transferred to the wire feed device 3.
A feed motor multi-core cable 10 and a control device 11 are led to supply power to a wire feeding motor (not shown) in the interior and drive, stop, and control the speed of the wire feeding motor.
A multi-conductor control cable 9 and a gas hose led to supply power to a trolley running motor (not shown) in the welding machine main body 4 and drive, stop, and speed control the wrong trolley running motor; Water cooling hoses (not shown) are required at a minimum, and the cables alone are heavy and complicated, making handling difficult and labor-intensive. As a means to solve this problem, the cables are hoisted by a hoist or crane and moved to the welding location, or a large-scale automatic welding device including couples is used.
A method of fixing the couples with a cable fixing jig and moving the entire welding device to the welding location has been used, but the device is complicated, takes up a large space, and is also expensive.
