In my last post I mentioned that we were having cut and arc quality issues whenever we would change out to a new electrode. This has been an ongoing problem. I recently discovered that cleaning up the flutes on the end of the electrode cures the problem. I mount each electrode in a lathe and gently file the top of the flutes and then I clean up each individual flute. This removes the burrs that are left behind from the manufacturing process. I have now successfully done this to about 5 electrodes and it works everytime. After about 1.5 years of problems with our TD A80 we finally have a system that works great.
Is anyone else experiencing any of these issues?
