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:
WB-P402L: Calibrated voltmeter and ammeter, a resistance load, and a cable with a cross-
section of 38 mm
2
or more
WB-P502L: Calibrated voltmeter and ammeter, a resistance load, and a cable with a cross-
section of 60 mm
2
or more
7.6.1
Adjustment of output current
1.
Connect a following resistance load to the output terminal.
●
WB-P402L:
0.1
Ω
, 12.6 kW or more
(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.)
WB-P502L:
0.09
Ω
, 22.5 kW or more
(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.
WB-P402L:
Connect a cable, having cable connectors at both ends (Specification: DIX SK 50/Part No.: 4734-016), to the
welding power source.
WB-P502L:
Connect a cable, having cable connectors at both ends (Specification: DIX SK 70/Part No.: 4734-021), to the
welding power source.
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.
The USER MENU will be displayed on the LCD panel.
