AUTOMATIC WELDING DEVICE CAPABLE OF PREVENTING CABLE FROM BEING TWISTED

摘要

PURPOSE: An automatic welding device is provided to easily carry out a welding work while preventing a cable from being twisted by effectively feeding an auxiliary welding agent without lowering direct current constant voltage characteristic. CONSTITUTION: An automatic welding device includes a torch section for performing a welding work, a driving section for directly driving a welding section, a control section for controlling an operation of each component of the automatic welding device, and a body section for supporting the welding section and a supporter. The torch section is divided into a straight motion part connected to a cylinder through a linear motion guide and a linear motion block and a rotary motion part connected to a motor through a helical gear. The motor is fixed to the straight motion part. A taper baring and a ball bearing are coupled to the rotary motion part.
