Failure to maintain
No.
malfunction
reason
Solution
1
Motor does not turn or
only operate in one
direction
Blown fuse Motor output
Replace the fuse, while
the
need
to
check
whether the lift motor
malfunction or jammed.
MOS which damaged one
of the driving motor
MOS pipe replacement
2
Arc voltage control is
unstable, shake torch
1, cutting the distance constant, the arc voltage is
stable.
2, the sensitivity is set too high, tuning control
sensitivity.
3, lifting the torch too fast.
3
Arc cutting torch can
not play
1. Confirm plasma power in working condition.
2, check the arc height is correct.
3, check the torch parts.
4
After
automatic
torch
decline
1, increase the "set arc voltage."
2, to extend the automatic control of time in
numerical control.
5
After automatic torch rise
1, the arc voltage is set too high.
2, no arc voltage or arc voltage positive and
negative reversed.
