7.6 Calibration Mode
The calibration mode can be used to calibrate the current and the voltage values indicated on the digital meter of the
welding power source as well as the actual output current and voltage values.
T I P S
•
To calibrate the current and/or voltage value with this function, the followings are necessary:
Calibrated voltmeter and ammeter, a resistance load, and a cable with a cross-section of
38 mm
2
or more
7.6.1
Adjustment of output current
1.
Connect a resistance load (0.1
Ƙ
, 12.6 kW or more) to the output terminal.
●
If no resistance load is applied, short-circuit between the output terminals by using a cable with a cross section
of 38 mm
2
or more. The following methods can be carried out to form a short circuit.
(1) Connect a cable, having cable connectors at both ends (specification: DIX SK 50 / part No.: 4734-016), to the
welding power source.
(2) Directly tighten the torch side cable (for connecting to wire feeder) and base metal side cable using a bolt and
nut.
2.
Connect an external ammeter or a measuring device that can measure an output current, such as a shunt
resistor.
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.
Set the current setting to 400 A.
6.
Turn ON the torch switch, and measure the output voltage.
●
After measuring the output voltage, turn OFF the torch switch.
