CALIBRATION CHECK

The calibration of the V350-PRO can be checked using a resistive load bank with the V350-PRO in mode 200. Mode 200 is a constant current test mode.

1.Press and hold in the Mode Select button.

2.Turn on the V350-PRO.

3.Rotate the output knob, while still holding the mode select button in, until the displays read “mode 200”.

4.Release the Mode Select button and the machine will be in mode 200.

5.With the machine in mode 200 apply a resistive load to the welding output terminals (approxi- mately .087 ohms) set the machine output to 300 amps and enable the Weld Terminals. (Weld Terminals Select ON).

6.Using the test meters note the output voltage and current.

7.The V350-PRO voltmeter must match the test meter reading to within +/- 1 volt.

8.The V350-PRO ammeter must match the test meter within +/- 5 amps.

9.If the voltmeter does not meet the specification then proceed to the Voltage Calibration

Procedure.

10.If the ammeter does not meet the specification then proceed to the Current Calibration

Procedure.

NOTE: Before attempting to calibrate the voltage or current setting of the V350-PRO, be sure to read the entire voltage or current calibration section. If the steps are not completed quickly, the machine will automatically leave the calibration mode with- out changing the calibration settings. The voltage and current calibration settings of the V350-PRO are completely independent of each other. Adjusting one will not affect the other.

VOLTAGE CALIBRATION

1.Connect the resistive load band (approximate- ly .087 ohms) and test voltmeter to the welding output terminals.

2.Press and hold in the Mode Select button.

3.Turn on the V350-PRO.

4.Rotate the Output Control knob until the dis- play reads “vol cAL”.

5.Release the Mode Select button.

6.Adjust the output control knob until the actual output voltage reading on the test volt meter is 20volts +/- .5 volts.

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

8.Adjust the Output Control knob again if neces- sary to make the actual voltage output 20 volts +/- .5 volts.

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

10.Repeat the above two steps if necessary.

11.Press and release the Mode Select button to save the calibration.

NOTE: If the Mode Select button is not pressed within 30 seconds after adjusting the Output Control knob the machine will leave the calibration mode and use the previous calibra- tion settings.
