3.02 Oxygen Plasma Pre-Charge Unit Installation
The Oxygen Plasma Pre-Charge Unit is an addition to the Gas Control console on the HD-3070 Power Supply. The
pre-charge unit is used to increase the line pressure of the plasma gas (Oxygen) at the start of a cut cycle. The pre-
charge unit is activated only during pre-flow when the gas selection switch is set to cut with Oxygen. This added
pressure provides improved consumable life during piercing. When cutting with any other plasma gas, the pre-charge
unit is not activated.
NOTE
The Thermal Dynamics Pre-Charge Unit is for use only with oxygen (O

)
gas.
