I was under the impression that you had to maintain some standoff unless you had a drag type tip. I am cutting some rings from an elliptical vessel that is about 0.100 thick. So one needs to move fairly fast to get the best cut. That is easier to do by dragging the tip.
So I went to the welding supply that I bought the Hypertherm 45 from and they were not much help. I came home and proceeded to make about a 3 ft long cut and everything worked great. When I tried to make the next cut it wouldn’t cut.
Wound up putting a new electrode in and everything worked again.
1. Is there a different drag type tip?
2. How is the electrode constructed? Is the first one repairable or is it toss able?
