Critical Machine Grounds: Run a 10 GA ground from z axis to x axis to the y axis to the frame so the slides are not acting as the
ground path.
Using an Ohm meter, double check that all the grounds are good on the table and visually inspect connections and verify solid
clean connections of wire and connector to bare metal. Remove paint where ground leads connect to table.
Target Voltage readings are always problems in plasma . mostly caused buy bad grounds or no grounds at all, and ungrounded
tables (i.e. bad connections from machine frame ground to table.)
Do not Coil ground leads.
Do not Coil extra CPC cable.
Use a Hypertherm CPC cable
If DIY CPC cable then make double sure wiring and pins are crimped properly and using proper sized wires, do not coil.
Run any outside wires that enter the cabinet as far away from any other wires and components as possible.
A coiled ground to the plate can alter thc voltage readings.
Target Voltage issues caused by Nozzle problems.
Check nozzle and shield, a bad pierce can ruin a nozzle in one pierce. causing voltage to be off.
Make sure you use correct amp nozzle for the amp setting being used.
