INSTALLATION INSTRUCTION
The machine is equipped with power voltage compensation equipment. When power voltage moves 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 cable is too long,
it may affect the performance of the power system. So we suggest you to use configured length.
1.
Make sure intake of the machine not blocked or covered, lest cooling system could not work.
2.
Use inducting cable whose section is not less than 6 mm² to connect the housing to the ground. The way is from the
ground-connecting screw at the back to the earth 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 "-"polarity and fasten it clockwise.
Put the fastening plug of the cable to fastening socket of "+" polarity at the front panel, fasten it clockwise, and the earth clamp at
4.
the other terminal clamps the work piece.
5.
Please pay attention to the connecting polarity, DC
welding machine has two connecting ways: positive
connection and negative connection. Positive
connection: holder connects with "-" polarity, while
work piece with the "+"polarity. Negative connection:
work piece with the "-" polarity, holder with the "+"
polarity. 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 so mistake and make sure the
voltage difference among permission range. After
the above job, installment is finished and welding is
available.
