INSTALLATION INSTRUCTION
The machine is equipped with power voltage compensation device. When the power voltage fluctuates
between±15% of rated voltage, it still can work normally.
When the machine is used with long cables, in order to prevent voltage form going down, bigger section
cable is suggested. If the cable is too long, it may have great affluence on the arc-striking or other
performance of cutting system, e.g. the HF arc-striking performance get weak or the system work
abnormally. So cables of configured length are suggested.
1.
Make sure intake of the machine is not blocked or covered to avoid malfunction of cooling system.
2.
Make sure the earth end of power interface has been reliably and independently grounded.
3.
Use pressure-resisting air pipe to connect the air intake and compressed air source, tight the joint
with hoop or other ways in case of gas leaking. Dry gas with suitable pressure and flow should be
supplied. If your air source cannot meet above requirements, you should consider using sole
compressor with enough power and air-
decompressing filter to ensure the machine
work normally.
4.
Install the air-electricity system plug to relevant
socket on the panel and fix it clockwise. Air plug
of the cutting torch and arc-keeping cable
should be connected to relevant socket, and
tighten the joint screw.
5.
Put cable plug to the socket on the panel and fix
it clockwise. On the other hand, clamp the work
piece with earth clamp.
6.
According to input voltage grade, connect
power cable with power supply box of relevant
voltage grade. Make sure there is no mistake
and the voltage of power supply does not
exceed permission range.
7.
Connect the cabled following the right
schematic, next steps can be performed then.
