USER MANUAL - 10 - YF-68E/A0
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. Ground the cables with section area no less than 6mm

to the housing, the way is connecting screw in the back of
the power source to ground device, or make sure ground terminal of power socket is firmly connected. Both ways
can be used for absolute safety.
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.
