Manual 0-2601 4-5 OPERATION
A. Coolant Level
Check the coolant level at the coolant reservoir at the
rear of the Power Supply. If the coolant is down from
the top of the reservoir more than 2 inches (50mm)
add coolant.
B. Deionizer Bag
Check the condition of the deionizer bag in the reser-
voir basket. If the bag is a yellowish brown (straw
color) then replace the bag.
C. Torch Parts
Check the torch for proper assembly. Install proper
torch parts for the application (refer to Maximizer
300 Torch Instruction Manual, Catalog No. 0-2573).
D. Input Power
Check the power source for proper input voltage.
Make sure that Power Supply is set for the proper
voltage. Close main disconnect switch or plug unit
in to supply primary power to the system.
E. Plasma Gas Supply
Connect desired plasma gas. Make sure gas sources
meet requirements (refer to appropriate Torch Instruc-
tion manual). Check connections and turn plasma
gas supply on.
F. Secondary Gas Supply
Connect desired secondary gas. Make sure gas
sources meet requirements (refer to Torch Instruction
Manual). Check connections and turn secondary sup-
plies on.
Select the desired secondary gas per the following:
1. If gas secondary is desired, set secondary mode
selector switch to gas cylinder symbol position.
NOTES
Tap water should only be used for secondary gas
on machine torches.
To use tap water there must be a Water Regulator
(Catalog No. 8-6118) installed between the water
source and the Power Supply.
2. If tap water secondary is desired, set secondary
mode selector switch to water tap symbol posi-
tion and connect tap water to the Power Supply
rear panel at the secondary water connection. It
may take two or three minutes for the water to
start flowing out the front of the torch.
3. If no secondary gas is desired, set secondary se-
lector switch to O
2
position.
NOTE
Refer to the Torch Instruction Manual for proper
secondary gas selection.
G. Plasma Gas Purge
Enable the system by doing one of the following:
• 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) in-
side 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).
