PROBLEM TO BE SOLVED: To provide an arc thermal spraying gun capable of efficiently supplying a compressed gas.SOLUTION: A first contact tip 10a is attached to a gun body 13 and supplies electric power to a first wire supplied by a first wire supplier. A second contact tip 10b is attached to the gun body 13 and supplies electric power to the first wire supplied by a second wire supplier. A plurality of compressed gas supply pipes 11 are attached to the gun body 13 to supply a compressed gas, and a step part 14 is formed within the compressed gas supply pipe 11 near its exit. An inner diameter of the compressed gas supply pipe 11 other than the step part 14, is 1.2 to two times an inner diameter of the compressed gas supply pipe 11 at the step part 14. As a result, efficiency of the flow of the compressed gas is improved.SELECTED DRAWING: Figure 5 |
