4. Place the red banded hose into the one-gallon container.
5. Turn the power supply power back on.
6. Hold down the ON (I) button on the power supply.
7. Start timing for 30 seconds, and then release the button.
8. Verify that the container is 1/2 full. If not 1/2 full, repeat this test and time discharge for 1 minute. After
1 minute verify that the container is at least 3/4 full.
8.1. If the one-gallon container is less than 3/4 full after step 8, go to
Verify Flow Rate to Torch
.
8.2. If the one-gallon container is at least 3/4 full after step 8, the problem is either with the flow switch or the
particulate filter.
• Remove filter element and re-connect coolant hose to cathode block on the rear of the power supply.
• Start power supply. If COOLANT FLOW LED remains illuminated, replace the flow switch. If the LED
does not illuminate, replace filter element.
Verify Flow Rate to Torch
1. Push power supply OFF (0) button and place main disconnect switch to OFF position (see warning on
previous page).
2. Remove the torch consumables.
3. Replace only the retaining cap on the torch. (Do not replace the electrode, nozzle and swirl ring back in the
torch.)
4. Place the empty one-gallon container under the torch.
5. Turn the power back on and press and hold down the power supply ON (I) button.
6. Start timing for 1 minute. The torch should deliver at least 1 gallon of fluid in 1 minute.
7. If the torch delivers at least 1 gallon of fluid per minute, then flow rate to torch is OK. Replace torch. If torch
does not deliver at least 1 gallon of fluid per minute, go to
Check Pump, Motor, and Solenoid Valve (V1)
.
8. If replacing the torch does not satisfy the flow switch, then replace torch leads.
