Hope someone can help.
I got a mobile CNC machine from China and an American Plasma from Primeweld.
The problem I have is that when I start the cut sequence the torch comes down and touches the metal and then retracts too far, and then just keeps lifting.
Without firing the torch the THC works perfectly.
I have done a lot of research and it seems my controller voltage is the issue. My Plasma machine can give 50:1 and 16:1, but the CNC is looking for 21:1.
How do I get around that?
