In order to take the JIS Welding Examination Exam, I purchased it for practice and production. I used it with N-2V. In the first layer backwave welding, there is only a stainless steel stick, and the stability of the arc at low current is outstanding and the bead shape also comes out beautifully. Also in the final finishing layer it is harder to undercut compared to LB - 47 etc, and bead appearance is glossy and finished beautifully It is recommended welding rod. Also, because the rod length is 400 mm with a 3.2 mm rod, it is a good place to weld with less margin, because welding can be done less.
