tightly to the power supply enclosure. Using an ohmmeter, measure zero
ohms between the braided shield and the ground stud on the power supply
sub-panel.
6. Inspect the braided shield and torch lead hoses for cuts or other signs of
damage. Replace the torch leads if damage is found.
Torch
1. Remove all consumables from the torch and verify that the anode-cathode
insulator (brown plastic) is in good condition, with 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. Check the o-ring on the torch for signs of damage. Apply a thin film of o-ring
lubricant to the o-ring.
5. Reassemble the electrode, swirl ring, and nozzle and install them in the torch.
6. Make sure that the retaining cap is hand tight and all parts are seated properly.
Work Ground
1. Using an ohmmeter, measure zero ohms between the power supply Work
Ground connection on the I/O p.c. board and the star ground point on the
cutting table. The star ground connection should be kept clean and free from
oxidation or corrosion. Use a wire brush to clean the connection point if
necessary.
Gas Supply
1. Check for signs of contamination in the gas supply lines and replace any
filters as necessary. The SR-45i requires clean, dry, oil-free compressed air
for good cut quality, as well as long consumable life.
2. Listen for gas leaks in the supply lines and in the internal plumbing system of
the SR-45i. Tighten any connections that are leaking. Leaks in the supply can
cause poor cut quality, as well as torch overheating.
