8.no arc striking,
and guiding arc
spraying out, but
there is high
frequency.
1.fast recovery diode of secondary
rectifying is damaged.
2.current-limiting resistor
R6,R7,R8 of guiding arc is
damaged.
3.high frequency leakage in cutter
output circuit.
1. change fast recovery diode under
same model.
2. check and change the damaged
current-limiting resistor of guiding arc.
3. check leakage point, and strengthen
insulation function.
9.supply power trips
1.three phases rectifier is damaged.
2.IGBT module is damaged.
3.other components in main control
circuit is damaged.
1.change a three phases rectifier under
same model.
2.change IGBT module under same
model.
3.check and change the damaged
components.
If the troubles cannot be resolved, please inform our local agent of the specific problems or
