INSTALLATION INSTRUCTION
The machine is equipment 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. Make sure the earth end of power interface has been reliably and independently grounded.
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.
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 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 there is no mistake and make sure the voltage difference among permission
range. After the above job, installment is finished and welding is available.

Electrode holder
Electrode holder above 500A is
suggested.
If distance of work piece and machine is too far (500-100m), and the cables (torch
cable and earth cable) are too long, please choose cable of bigger section to
minimize the reduction of the voltage.
