PURPOSE: A weaving torch device for automatic welding is provided to ensure stable weaving by preventing distortion in the waveform of voltage graph according to the weaving pattern. CONSTITUTION: A weaving torch device for automatic welding comprises a body(110), a welding tip(120), a hinge shaft(130), a current(100), a lower case(200), an electromagnet(300), an upper case(400), and a support spring(500). The welding tip is connected to the tip of the body. The hinge shaft protrudes from both sides of the tip of the body. The current is installed inside the lower case. The electromagnet is installed inside the upper case. The support spring is formed on the lower side of the current to support the body.
