1.
Make sure copper tip must not connect to work piece directly when user is cutting.
Torch should be inclined and it is 1 mm from inter-hole of copper tip to work piece
in order to protect copper tip.
2.
As arc-supporting cutting machine ,if arc-supporting frequency is down or there is
no arc-supporting ,user may be get rid of oxidized film of inter electrode by abrasive
paper .Then machine will be operated normally .
MAINTENANCE AND CHECK TROUBLE
Maintenance
1.
Remove dust by compressed air regularly .If cutting machine is placed in
environment where condition is polluted with smoke and dust, cutting machine must
be removed dust every day .
2.
Pressure is adequate to cutting in order to protect little components.
3.
Check the electrify connectors and make sure the connectors are connected firmly
(specially connect and insert components),tighten the connectors.
4.
Avoid water into machine and machine become damp, or the machine must be dried
in time and measured insulation by meter. After there is no problem, the machine
can be operated .
5.
If the machine will not be used long time, it should be put in its own packing box
and store in dry environment.

Faults
Resolvable Methods
1.Switch indicator is on ,fan is not
working and control knob is out of work.
1.Over voltage protection is working.Close machine
then open it again after several minutes.
2.Switch indicator is lit and fan is
working .However ,press control knob of
torch ,there is no HF arc-striking sound
and electromagnetic valve is not working.
1.
Check if torch is open circuit.
2.
Check if control knob of torch is damaged.
3.
Part of assistant power of top board is damaged and
there is no DC 24v output.
3.Switch indicator is lit and fan is
working .However ,press control knob of
torch ,there is no HF arc-striking sound
and inter red diode is lit .
1.
Check if MOS K1170 of top board is damaged
(driver mould is damaged ).
2.
Rising transformer of bottom board is damaged.
3.
Control mould is damaged.
4.
Switch indicator is lit and fan and
electromagnetic valve are working.
However, there is no sound of HF
arc-striking and inter red diode is not
lit.
There is some trouble in part of arc-striking ,such as:
1.
It is too far between discharge tip or there is
adhesion in discharge tip .
2.
Primary coil of arc-striking transformer is damaged
or poor contact.
3.
Check if four times voltage rectifier diode is
stricken.
4.
Check if HF electric capacity 102/10KV is leaking.
Relay is damaged.
5.Other of machine is normal ,but arc is
not be stricken when it is be operating.
1.
Input voltage is too low.
2.
Pressure of air compressor is too high or too low.
