Functional test

1. Each safety related function judged as relevant by the test personnel shall be checked
for correct operation.
Conformity shall be checked by operating the device and by checking whether the
welding power source operates correctly.
2. Check the supply circuits on/off switching device
a. Disconnect the welding power source from the mains supply.
b. Remove the cover.
c. Turn the mains switch of the the welding power source to
OFF.
d. Measure from the supply pins of the mains plug to the EMC
board, 2AP1.
S
Measure L1 - L1 of 2AP1. Required value, open circuit
S
Measure L2 - L2 of 2AP1. Required value, open circuit
S
Measure L3 - L3 of 2AP1. Required value, open circuit
e. Turn the mains switch of the the welding power source to ON.
f. Measure from the supply pins in the mains plug to the EMC
board 2AP1.
S
Measure L1 - L1 of 2AP1. Required value, less than 0.5 Ω
S
Measure L2 - L2 of 2AP1. Required value, less than 0.5 Ω
S
Measure L3 - L3 of 2AP1. Required value, less than 0.5 Ω
g. Reassemble the cover.
3. Tig 3001i: Check the magnetic gas valve
a. Operate the trigger of the torch and check by means of the of the gas flow wether

4. Check signal and control lamps
Check the function of the display indicators by turning on the unit and visually check the
front panel.
The LED test starts with all LEDs dark, then the diodes are turned on and off, one at a
time, until all diodes have been tested. If the test detects a fault, no fault code will be
logged.
Then the display test is made in the same way as the LED test but for each segment of
the digits in the display. If the test detects a fault, no fault code will be logged.
Finally the software version of the welding data unit is displayed.
5. Check the function of the welding power source by welding.
6. Disconnect the welding power source from the mains supply.
7. Write the test report.
See Test report, page 69).
8. If the unit passes all the tests, attach appropriate label with signature and date of the
