Faults
Resolvable Methods
1.Open the air switch, fan does not work and
there is nothing in indicator .knob of torch is out
of working .
1.Part of assistant power of control panel is damaged and
there is no DC 24
V
output .
2.Open the air switch ,fan is working .Press knob
of torch ,electromagnetic valve is working ,there
is no sound of HF arc-striking and red diode is lit.
1.
Circuit of torch is broken .
2.
Knob of torch is damaged .
3.
Part of assistant power is damaged and there is no DC
24
V
output .
3.Open the air switch ,fan and indicator are
working . Press knob of torch , electromagnetic
valve is starting ,there is no sound of HF
arc-striking and red diode is not lit .
There is some fault 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 .
5. Relay is damaged .
4.As
arc-supporting
cutter
such
as
CUT60/70/100/120 ,if it can not support arc or
support arc weakly .
1.
Wipe the electrode by abrasive cloth .
2.
Magnify arc-striking tip suitably .
