Hi everyone.
Have a problem and don't know there it comes from.
I bought home made cnc table. it have Gh-2012ah cnc controler and GH-HC31 thc. I am new at cnc plasma cutting, was trying some setting and did few cuts. In some moment i reconiz my THC controler doesn't do it job anymore. I found my thc divider was damaged. Electronics fixed it for me. But it burnt-out again after first cut. I ordered brand new from China and waiting for it. But I don't know what the reason and how to sort it out it.... I use cnc source Stahlwerk 120A, it doesn't have divider inside. So thc divider set at 100:1 ratio.
Maybe any one have any ideas what's wrong.. I didn't do any changes before it was fine, only did random changes on controller to improve cutting quality, like pierce time and etc.
Thanks for help. Sorry for my English skills...

Re: Votage Divider Problem
Can you try and clean off the soot with some isopropanol alcohol and a cotton swabs?
It looks like the trace has burned out and I am interested to see how close those traces are.

Re: Votage Divider Problem
quick question did the first failure look the same that is some serious soot inside and outside. Could you have hooked it up wrong. If the original worked for a while and failed that may have been just a normal failure. Things happen with electronics for different reasons so that why the question.

In the mean time, are you able to disable your thc and cut by setting your cut height manually?Vaidis wrote: ↑Wed Sep 28, 2022 2:54 pm Hi everyone.

That's good to know. At least you are still up and running until you resolve your thc issues.
Good luck!
