PURPOSE: A device for supplying the welding power for a vehicle welding line is provided to prevent the delay of the welding work due to the interference between peripheral parts and a panel, to simplify the welding procedure by removing the necessity of a shift device, and to reduce the cost for the welding process by compacting a device added to weld the interfering parts. CONSTITUTION: A device for supplying the welding power for a vehicle welding line comprises a spot gun(100) installed at the welding portion in which the peripheral parts interfere with a panel and performing welding by being driven with the input of the power supplied from the exterior, a power supply unit(200) forming a power supply circuit with the spot gun and supplying power to the spot gun by being operated with an external force, and a welding robot(20) applying the external force to the power supply unit.
