Correct the difference between the measured value and the set value by using the values of internal functions
F39 and F40.
●
When the value of F39 is "1", it is equivalent to the output current of 1 A. To increases the output current, increase
the numerical value to + side.
If the output current needs to be adjusted finely, change the value of F40. When the value of F40 is "0.01", it is
equivalent to the output current of 0.01 A.
8.
When you have adjusted the output current, turn ON the torch switch to confirm the adjusted result to the set
value.
●
Make sure that the value of the output current is within the following limits.
350±1 A
●
If the current value is out of this range, readjust the values of F39/F40.
9.
When the calibration has been completed, turn OFF the power switch of the welding power source, and then
turn ON the power source again after the operation panel has completely turned off.

Adjustment of output voltage
1.
Connect a following resistance load to the output terminal.
●
0.1
ƺ
, 12.6 kW or more
(If no resistance load is applied, open the circuit between the output terminals.)
2.
Connect an external voltmeter and a voltage detection line to both ends of the resistance load (if no load is
applied, connect to the output terminal).
3.
While both DISPLAY CHANGE keys are pressed at the same time, turn ON the power switch.
4.
Turn the screen operation knob to select "CALIBRATION MODE", and press the knob.
5.
(If the resistance load is connected) Turn ON the torch switch, measure the voltages of the resistance load at
its ends, and set the output current so that the voltage is within the range of 30.0±0.1 V.
B
If the resistance load is not connected to the output terminals (open circuit), the maximum no-load voltage will
be output, and the measured output voltage value will not change even if the output voltage setting is changed.
Therefore, in this case, the output voltage is adjusted at the maximum no-load voltage.
