OPERATION
Daily Operating Procedure
The HD3070 system can be operated in either the local or remote mode. Prior to operation, ensure that your
cutting environment and that your clothing meet the safety requirements outlined in the Safety section of this
manual. If problems occur during start up, refer to Section 3, Installation and check the installation data.
Local Mode
To start up the HD3070 system on a daily basis, in the local mode, proceed as follows:
1. Select consumables based on the material to be cut. If the consumable parts are to be reused, check for wear
or damage. Refer to Changing Consumable Parts in this section.
2. Ensure that the torch is perpendicular to the workpiece (0° and 90°) to get a clean, vertical cut. Use a square to
align the torch.
3. Select either oxygen (O
2
), AIR or a mixture of argon-hydrogen and nitrogen (H35 & N
2
) as the plasma cutting
gas using the PLASMA GAS SELECTION toggle switch.
4. Apply system power by setting the main disconnect switch for the power supply to On and turning on the power
supply by doing the following:
• Depress POWER ON (1) switch (PB1) until the STATUS-COOLANT FLOW LED lights.
• Ensure the green POWER ON indicator (LT1) remains lit. If not check the STATUS LEDs on the power supply
and check for plasma and gas system error messages on the gas console LCD display. Refer to Figure 4-3
and the Error Messages list.
Note: If the COOLANT FLOW LED does not light, unscrew filler/vent cap on coolant tank (item 9,
Figure 6-10). Add 2 quarts (1.9 liters) of coolant.
5. Also at initial startup, the gas lines will be automatically purged for 40 seconds total. The gas console LCD
display, Figure 4-3 field E will indicate PURGE PRELFOW for 20 seconds and then PURGE CUT FLOW for
20 seconds.
6. Ensure that both the selected plasma and shield inlet gas supplies are available at 120 psi (8.2 bar) dynamic
pressure on the gas console LCD display fields (plasma and shield). (See Figure 4-3.)
7. Set the test cut and test preflow gas flowrate percentages. To do this, proceed as follows:
• Set the test preflow flowrates (1) and (2) as specified in the Cut Chart.
• Set the shield test cut flowrates (3) and (4) and plasma test cut flowrate (5) and (6) as specified in the Cut
Chart.
• Set the Test Preflow/Run/Test Cut Flow switch (S2) to Run.
