PURPOSE: A wire feeding device installing an attachable remote controller is provided to display an actual welding current value, an actual welding voltage value and an actual wire feeding speed and to be operated in actual welding condition. CONSTITUTION: A welding current detecting sensor (a shunt or a hall sensor) (20) and a wire feeding speedometer(26) are attached to a wire feeding device(2). In an attachable remote controller(32), a measuring ampere meter(23) and a measuring voltmeter(24) are connected to the welding current detecting sensor through an amplifier(21) and a decelerator(22) and a wire feeding speedometer(25) is connected to the wire feeding speedometer of the wire feeding device. Then, a welding current setting variable resistor(27) and a welding voltage setting variable resistor(28) are installed in the attachable remote controller. Thus, an operator accurately sets welding conditions by adjusting the variable resistors while observing welding condition displays with the naked eye.
