The Techniques Breakdown and Analysis
No. Breakdown Analysis Solutions
1 Work piece is not cut
thoroughly The cutting current is too
low Adjust ‘Cutting thickness
Mode Switch’ to ‘Thick
Mode’
The cutting speed is too
rapid Slow down the cutting
speed
Torch electrode or nozzle is
burn out Replace electrode or noz-
zle
Cut thickness exceeds the
limit of the cutter Replace with high-power
cutter
2 Slag drop out from
the Cutting Mouth of
Work Piece Cutting Speed is too slow Accelerate cutting speed
Cutting Electrode or Nozzle
is burnt Replace electrode or noz-
zle
Cutting current is too high Adjust cutting thickness
mode to ‘thin’ mode
3 Pilot is not stable
during operation Compressed gas is too low
or too high Adjust pressure
Electrode of cutting torch
or nozzle is burnt Replace electrode or
nozzle
Connection between
cutting cable and work
piece is poor Connect firmly
Cutting speed is too slow Adjust speed
Input AC voltage is too low Adjust power supply or
voltage
4 Cutting thickness is
not up to the rated
standard
Slag drop out from
the Cutting Mouth
of Work Piece
Pilot is not stable
during operation Input compressed air pres-
sure is too low or too high Adjust air pressure
Input compressed air flow is
too low Adjust air flow
Cutting speed is too quick Slow cutting speed
Material of work piece is not
symmetry with the thickness
standard Adjust
Nozzle or electrode is burnt Replace nozzle or elec-
trode
Nozzle type is not right Replace with a suitable
nozzle
Cutting mouth is not vertical Adjust cutting mouth angle
Gas leak from the gas circuit,
making the true cutting flow is
not enough Examine and repair the
gas circuit
Input power supply is a bit
low Adjust the power supply
Input or output lead is too
thin or pressure is too big Widen down-lead
Cutting speed is too slow Adjust speed
Input AC voltage is too low Adjust power supply or
voltage
5 Cut is a bit declin-
ing Nozzle or electrode is burnt Replace nozzle or elec-
trode
The installation position of
nozzle and electrode is not at
the same axes Install again correctively
Cutting speed is too high Adjust cutting speed
Nozzle axes is not plumb with
the plane Adjust the torch angle
