PURPOSE:To provide a titled welding torch which stabilizes beads, decreases welding defects and improves reliability of welding by attaching or building a wire straightener to or into a welding torch thereby eliminating the bend of a wire and decreasing the fluctuation in the wire extension thereof. CONSTITUTION:A wire straightener 9 is attached or built to or into a welding torch body 1 at the top end of a conduit cable 3. A welding wire 2 under feeding is straightened reactilinear by the stationary rollers 9a, 9b and moving roller 9c of the straightener 9 and is supplied from the top end of the torch 1 to the weld zone. The fluctuation of the weld point and the fluctuation in the wire extension owing to bending are decreased, beads are stabilized and the reliability of welding is improved. |
