6
The machine start to Setting
time
of 1、increase SET-PIERE time
work before the SET-PIERE is too short 2、adopt the arc feedback signal
accomplishment of
of Plasma itself
arc-beginning
7
Plasma produce arc When we use the Prolong the delay time of CNC
before the IHS
EXARCON signal, the IHS
delay-time of CNC
controlling is too short
8
Cutting torch can not 1、Confirm the working situation of Plasma power
produce arc
2、Check the height of IHS
3、Check the cutting torch fittings
9
Plasma cutting torch 1、Check the connection of working lead
can not transfer to 2、Check the cutting torch fittings
workpiece
10
Cutting torch move Prolong the time of piercing hole in the CNC system
before the fulfillment
piercing hole
11
The CNC control start 1、Increase the setting of “given voltage”
move, the cutting 2、Prolong the automatic time in the CNC system
torch then begin work 3、Decrease the setting of over-voltage
4、Check the situation of automatic signal or cornering signal
of CNC system
12
Plasma arc out after 1、 Delay-time is too long
the arc transferring
and piercing hole
13
When do the IHS, the 1、Time of HIS is too short
cutting torch touch the 2、Induced lead connect with protection badly
steel plate but no
movement upwards.
14
Cutting torch still 1、Bad checking cable and contact of the Torch Retaining
press the steel plate Cap
downwards and no 2、Proximity switch is damaged
arc-producing
3、“WORK” in the high adjusting is bad connection with
earth
