<p>PROBLEM TO BE SOLVED: To provide a welding equipment by which the bending of a power cable is minimized, the generation of a welding defect due to an incomplete gas shielding, the generation of an instability of an arc due to an incomplete wire feeding, the generation of a grounding due to the wear of the external cover of the power cable, and the generation of a welding defect due to an incomplete gas shielding are prevented, thus the replacement of the power cable is unnecessitated. SOLUTION: In the welding equipment, a non-adhesive resin tape 1 whose inner diameter is slightly larger than the outer diameter of power cable 20 is helically wound on the outer peripheral face of the power cable 20.</p> |
