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 the machine is used with long cables, in order to prevent voltage from going down, bigger sect
i
o
n
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.

.
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.
4. 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
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 "+" terminal. Negative connection:
work p
i
ece with the"-" terminal, holder with the "+'
terminal. Choose suitable way according to the
work

tuation
.
If unsuitable choice is made, it wil
cause unstable arc, more spatters and conglutination.
If such problems occur, please change the polarity ol
the fastening plug

6. According to input voltage grade, connect power cable
with power supply box of relevant voltage grade. MakE
sure no mistake is made and make sure the voltage

erence is among permission range. After the abovE
job, installation is finished and welding is available.

If distance of work piece and machine is too far (50-1 00m), and the cables
� (torch cable and earth cable) are too long, please choose cable of bigger
ill
section to minimize the reduction of the voltage.
