I have to agree with Navigator. In order for us to help troubleshoot your problem you need to clearly describe all of the equipment, and what it is doing.
Stating that you have a 60 Amp plasma tells me nothing, there are a dozen different 60 Amp plasma systems available. If you tell me its a Hypertherm Powermax1000, and you are trying to cut 1/4" steel at 86 inches per minute at 60 Amps with a pierce height of .15" and a cut height of .08", yet the torch is dragging on the plate.....then I would ask a few more questions, we would go back and forth a few times.....and eventually we would solve your issues. Instead you are just rambling about how the machine did not work perfect on day one. There is a learning curve with every cnc plasma, regardless of the brand. It may be a turnkey machine, but you have to learn how to use it. There are dozens of parameters to set to cut one part....when they are set incorrectly, the machine will display symptoms similar to what you sort of described. I'm still willing to help, but not unless you help us understand what you are experiencing.
