This question has been answered, but the answer is not consistent with the proposed problem, I want to ask is how long after the use of suitable electrode, can not damage the electrode holder, but also save, thank you!
Don't want to damage and save the electrode, the electrode holder, you get 40mm on the line, mainly to see your operating
Current magnitude plus experience
After we calculate the utilization rate, the remaining 50mm of the welding rod is welded
