Installation Instruction - HBM Machines ARC 200 Handbuch

5. 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 section
cables is suggested. If the cable is too long, it may affect the performance of the power systems. 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 systems.
2. Ground the cables with section area no less than 6mm
in the back of the power source to ground device. Ensuring safety, also can use two methods
meanwhile.
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
workpiece with the "+" terminal. Negative connection: workpiece 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.
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 difference is among permission range. After the
above job, installation is finished and welding is available.

If the distance of workpiece 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.
