The present invention suggests a welding system with a brushless DC (BLDC) motor capable of providing better usability for a user and preventing a limitation to the movement of a welding device body and an auto carriage due to outgoing feeders mutually different. To achieve this, a feeder shares a power source line with the auto carriage and providing a first power source to the auto carriage by receiving the first power source from the welding device body. The auto carriage is composed of: the BLDC motor; a controller for controlling the operation of the BLDC motor; and a conversion unit converting the first power source to a second power source and providing the second power source to the BLDC motor and the controller. |
