[0058] Next, examples of the present invention will be described in comparison with comparative examples that deviate from the scope of the present invention.
[0059] The following Table 1 shows the welding conditions, and the following Table 2 shows the evaluation criteria of the arc ignitability. In addition, all of the following examples and comparative examples are welding wires based on a solid welding wire made of a non-copper-plated steel wire having a wire diameter of 1.2 mm. In addition, all the oils used in the next examples and comparative examples contain polyisobutylene as a main component.
[0060] Protective gas
[0061] Arcing
[0062] In addition, in the welding test, an arc generation time of 3 seconds and an arc stop time of 30 seconds were regarded as one set, and 100 sets were repeated. In these 100 groups, according to the total number of evaluation points, they were graded on the basis of the following Table 3.
