PURPOSE: An extension single cable of an arc welding device is provided to prevent safety accidents, such as an electric shock, and to improve work convenience with regard to maintenance and economic feasibility with regard to replacement costs. CONSTITUTION: An extension single cable of an arc welding device is installed between main feeders(40a,40b) and extension feeders(50a,50b). An adapter(31) which transmits a welding current, a gas hose(34) which transmits gas, and a grip in which a power line(33), which is connected to the adapter(31) and supplies an electric current, is stored are installed at both ends of the extension single cables(30a,30b). A fuse(35) is further installed at the power line inside the extension single cable grip which is connected to the extension feeders. A fuse holder(32a), which fixes the fuse, is formed inside the grip. The extension single cables are extended by the extension feeders, and are connected to a carriage(20a,20b).
