INSTALLATION INSTRUCTION

The machine is equipped with power voltage compensation equipment. When the power voltage fluctuation is betweent15% 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 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 6mm2 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 fasteni 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 Power Supply terminal at the front panel, fasten it cockwise, and the earthclamp 1 phase 220 at the other terminal clamps the work piece
5. 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 piece with the terminal, holder with the terminal. Choose suitable way according to the working situation. If unsuitable choice is made, it will cause unstable arc, more spatters and conglutination. If such problems occur, please change the polarity of the fastening plug Earth Clamp
6. According to input voltage grade, connect power cable with power supply box of relevant voltage grade. Make sure no Electrode Holder mistake is made and make sure the voltage difference 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 (10-50m), and the cables (torch cable and earth cable) are too long, please choose cable of bigger section to minimize the reduction of the voltage
