OWNER’S MANUAL - 5 - YF-12O A/0
INSTALLATION INSTRUCTION
The machine is equipped with power voltage compensation equipment. When the power voltage fluctuation is
between±15% of rated voltage, it still can work normally.
When use long cable, in order to prevent voltage form going down, bigger section cable is suggested. If the cable is too
long, it may affect the performance of the power system. So cables of configured length are suggested.
1. Make sure the intake of the machine is not blocked or covered to avoid malfunction of cooling system.
2. Ground the cables with section area no less than 6mm

to the housing, the way is connecting screw in the back of
the power source to ground device .
3. Correctly connect the arc torch or holder according to the sketch. Make
sure the cable, holder and fastening plug have been connected with the
ground. Put the fastening plug into the fastening socket at the “-“terminal
and fasten it clockwise. Put the fastening plug of the cable to fastening
socket of “+” terminal at the front panel, fasten it clockwise, and the earth
clamp at the other terminal clamps the work piece.
4. Put the fastening plug of the cable to fastening socket of “+” polarity at
the front panel, fasten it clockwise, and the earth clamp at the other
terminal clamps the work piece.
5. Please pay attention to the connecting terminal, DC welding
machine has two connecting ways: positive connection and
negative connection. Positive connection: holder connects with
“-“terminal, while work piece with the “+”polarity. Negative
connection: work piece with the “-“terminal, holder with the “+”
terminal. Choose suitable way according to working demands. If unsuitable choice, it will cause unstable arc, more
spatters and conglutination. If such problems occur, please change the polarity of the fastening plug.
6. According to input voltage grade, connect power cable with power supply box of relevant voltage grade. Make sure
there is no mistake and the voltage of power supply does not exceed permission range. After the above job,
installation is finished and welding is available.
If distance of work piece and machine is too far (50-100m), and the cables (torch cable and earth
cable) are too long, please choose cable of bigger section to minimize the reduction of the voltage.
