Hello, I have had this THC300 going on 4 years now and still have not got it working. I cannot seem to find and support for it. My first question in the setup is this line i copied and pasted from the setup manual that confuses the heck out of me.

With Mach3 running click on the Reset (solid Green) button on the lower left corner of the main screen. The Ready LED will light. And the set volts will be on the meter.
Adjust the set voltage to about 87volts.
Click on the “Torch ON” button the Mach3 screen. You will hear a relay click on the sensor board and see the Torch On LED light up on the Front Panel.
Center the coarse and fine controls (pointers UP).
The meter will drop to zero volts. This would normally read the actual tip volts at this time.


What Meter are they talking about? And how do you set it to 87 volts? I have been ruining tips too often because I cannot get this thing set right. Please help!!! Am I SOL on an outdated system?
