CALIBRATION CHECK

If either the Control PC Board or the Wire Feed Motor is replaced,

TEST PROCEDURE

the Calibration should be checked

1. .Connect the feeder to a CV welder or an external 25VDC power suppy (See the Wire Feeder test).

2. Run the motor at MAX speed for about 2 minutes before doing the Calibration Check.

3. Load the LN -23P with .068 Innershield wire.

CAUTION: If connected to a welder, the wire will be “hot” whenever the trigger is closed. If connected to an external supply the wire will be at that potential.

4. Put the ʻReduced Speed Switchʼ in Position 1.

5. Set the Wire Speed Control to exactly 30 ipm.

6. Pull the trigger and measure the wire speed, preferrably with a K-283 Wire Speed Meter. The speed should be 30 ipm +/-1.

If a K283 is not available, feed wire fo a set time. measure the length and multiply by the appropriate factor. (ex. length after 15 seconds x 4 = ipm).

Do this several times and take the average.

7. If speed is not correct, adjust R14 on the Control Board and re-test. (Clockwise rotation increases speed). Repeat until measured speed is 30 ipm.

8. Set the Wire Speed Control to exactly 170 ipm.

9. Measure the speed as in Step 6. If not correct, adjust R10 and re-test until speed is 170 ipm. NOTE: Do not adjust R14 after setting R10.

10. Set the Wire Speed Control to 100 ipm and check that the speed is 100 ipm +/-2.

11. Put the Reduced Speed Switch in Position 2.

12. Feed wire and check that the reduced speed is 83 ipm +/-3.
