This is the process I follow:
1 make sure z-axis is properly calibrated (if you command 1 inch it moves 1 inch) you can use a Bernier to adjust the Z axis Scale.
2 you can use a gauge to calibrate the float travel.
- Adjust piercing high to .5" in the default tool and save it.
- Press probe test and when the torch goes to piercing high use the gauge to measure .5" from work piece to torch.
- If measurement is not correct adjust float travel and repeat the measurement.
- Change piercing high to .125", on the default tool (not forget to save)
- Press probe test and verify piercing high is .125 in.
3 Once the Z axis is properly calibrated, we need to make sure the voltage is properly calibrated according to the plasma power supply charts.
what I do (No sure if it is the best way to do but work)
- select a thick material, may be 3/4" mild steel then set the cut high according to the power supply chart cutting high for instance for a Hyperterm Powermax 125
the Torch-to-Work Distance is 0.18" piercing height .45", Cut Speed is 42 ipm, and voltage is 164V.
- Set these settings to your default tool and make sure the working piece is as much flat as possible,
- Cut a line, let say 6 inches but no use THC, during cut make a note of the voltage displayed.
- Then adjust the voltage scale to make sure these settings give you 164V.
- repeat the process for a 1/4" material, and verify the voltage is according to the table.
after this exercise you can set up the tools according to the Plasma power supply tables.
this is not a perfect procedure but work for me.
