Maintenance and Troubleshooting SR-100i User’s Manual
Section 5 Maintenance and Troubleshooting
Warning: Only qualified maintenance personnel should perform
maintenance on the SR-100i system. The system utilizes potentially fatal
A.C. and D.C. voltages. All maintenance should be performed with
safety in mind. Be aware that the large blue electrolytic capacitors
inside the power supply store large amounts of energy even after power
has been removed from the system. Wait at least five minutes after
turning off power before touching any of the internal components
.
Daily Procedures
SR-100i Power Supply
1.
Verify that the white A.C. Power light is illuminated whenever primary A.C.
power is applied to the system.
2.
Depress the green On push button and verify that the fan motor is on.
3.
Place the Gas switch in the Set position and verify that air is flowing through
the torch.
4.
With the Gas switch in the Set position, adjust the regulator on the rear panel
of the SR-100i to 85 psi. Return the Gas switch to the Run position.
5.
Raise the torch 2 inches above the workpiece. Apply a start signal to the SR-
100i using the CNC control. The pilot arc should be established in
approximately 2 seconds. The arc should extend approximately 1 inch from
the nozzle and should make a smooth swishing sound. If a popping or
“motorboat” sound occurs, there may be a problem that needs correction.
** WARNING **
Remove primary power from the system before performing the following
procedures
SR-100i Torch Leads
1.
Check the braided shield for nicks or cuts. If the braided shield is damaged,
make sure the hoses are in good working condition. If there are any holes in
the hoses, the torch leads must be replaced.
SR-100i Torch
1.
Remove all consumables from the torch and verify that the anode-cathode
insulator (brown plastic) is in good condition and has no signs of arcing.
2.
Check all consumables and discard any damaged items.
3.
Verify that the electrode seat is clean to insure proper electrical contact.
4.
Reassemble the electrode, swirl ring, and nozzle and install them in the torch.
5.
Make sure that the retaining cap is hand tight and all parts are seated properly.
