9.Wait for the machine’s output to be automati- cally turned off and then back on.

10.Adjust the output control knob again if neces- sary to make the actual voltage output 20 volts +/- .5 volts.

11.Wait for the machine’s output to be automati- cally turned off and then back on.

12.Repeat the above two steps if necessary.

13.Toggle the mode select switch up and release the switch to save the calibration setting.

14.The right display will display the message “VcAL SAVEd”. Within 5 seconds, hold the mode set switch in the up position until the right display stops blinking.

15.The machine will reset to normal operation after a few seconds.

NOTE: If the mode select switch is not toggled within 30 seconds after adjusting the out- put control knob, the machine will leave the calibration mode and use the previ- ous calibration settings.

CURRENT CALIBRATION

PROCEDURE

1.Connect the resistive load bank of approx.

.106 ohms and test ammeter to the welding output terminals.

2.Toggle and hold the mode select button in the up position.

3.Turn on the Power Mig 300.

4.Rotate the output control knob until the dis- play reads “cur cAL”.

5.Release the mode select switch.

6.The left display will change to “lcAL” to indi- cate that current calibration is in progress.

7.The right hand display will scroll the following message: Adj rEnc SorEAL cur = 250A.

8.Adjust the right hand output control knob until the actual output current reading on the test ammeter is 250 amps +/- 2A.

9.Wait for the machine’s output to be automati- cally turned off and then back on.

10.Adjust the output control knob again if neces- sary to make the actual output current read- ing on the test ammeter 250 amps +/- 2A.

11.Wait for the machine’s output to be automati- cally turned off and then back on.

12.Repeat the above two steps if necessary.

13.Toggle the mode select switch up and release the switch to save the calibration setting.

14.The right display will display the message “lcAL SAVEd”. Within 5 seconds, hold the mode set switch in the up position until the right display stops blinking.

15.The machine will reset to normal operation after a few seconds.

NOTE: If the mode select switch is not toggled within 30 seconds after adjusting the out- put control knob, the machine will leave the calibration mode and use the previ- ous calibration settings.
