Manual 0-2568 37 OPERATION
• Turn the Enable switch to ON at the front panel of
the RC6010 Remote Control
• Signal supplied through the CNC control cable
• Signal supplied from a customer supplied switch
connected to the CNC terminal block (TB2) inside
the Power Supply
Move the Power Supply ON/OFF switch to the ON
position (see note). The Enable Signal must be turned
ON either by a switch or contact closure.
NOTE
In systems using more than one Power Supply both
front panel ON/OFF switches must be ON.
An automatic gas purge will remove any condensa-
tion that may have accumulated in the torch and leads
while the system was shut down. The gas purge du-
ration is 40 seconds. After the purge is complete, if
the RUN/SET/PURGE switch is in SET position, gases
will flow. If the switch is in PURGE position only
plasma gas will flow. If the switch is in RUN position
there will be no gas flow.
NOTE
RUN/SET/PURGE may be selected at the RC6010
Remote Control. Both switches must be in the
RUN position for normal operation.
H. Current Output Level
Single Power Supply System:
Select the desired current output level from 50 to
150 amps.
Dual Power Supply System:
Select the desired current output level from 100 to
300 amps.
I. Pressure Settings
Move the RUN/SET/PURGE switch to SET position.
Set plasma and secondary pressures (refer to Maxi-
mizer 300 Torch Instruction Manual 0-2573).
J. Additional Gas Purging
NOTE
Additional gas purging should be done when
switching to a new plasma gas. This will make
sure that the old gas in the lines has been purged.
If additional purging of the plasma gas line is neces-
sary, move the RUN/SET/PURGE switch to PURGE
position. In PURGE mode, the GAS indicator will be
OFF because only plasma gas flows and the secon-
dary gas flow switch is not satisfied.
K. Ready for Operation
Return the RUN/SET/PURGE switch to RUN posi-
tion.
The system is now ready for operation.
NOTE
Refer to Appendix II for a detailed block diagram
of the Sequence Of Operation.
4.06 System Operation
NOTE
Frequently review the safety precautions at the front
of this manual.
This section contains operating information which is spe-
cific to the power supply. Detailed operating informa-
tion for torches can be found in the appropriate Torch
Instruction Manual.
WARNINGS
Disconnect primary power at the source before as-
sembling or disassembling power supply, torch
parts, or torch and leads assemblies, or adding cool-
ant.
It is not enough to simply move the ON/OFF
switch on the unit to OFF position when cutting
operations have been completed. Always open the
power supply disconnect switch five minutes after
the last cut is made.
A. Operational Suggestions
The suggestions below should be followed in all cutting
and gouging operations:
1. Wait five minutes before setting the ON/OFF switch
to OFF after operation. This allows the cooling fan to
run to dissipate operating heat from the power sup-
ply.
2. For maximum parts life, do not operate the pilot arc
any longer than necessary.
3. Use care in handling torch leads and protect them from
damage.
4. In continuous cutting applications using CO2, it is of-
ten necessary to manifold four to six cylinders together
to maintain adequate flow at operating pressures.
