Notes of anti-interference (Specially pay attention when work on CNC automatic
cutting equipment)
Cover the whole torch cable (from torch holder to output terminal ) of the
cutter with shieldinglayer,the shieldinglayer should be metal hose or shielding
net pipe made of aluminum or copper, metal materials which is magnetic
conducted can not be used, the shielding layer don't need to connect with
ground;
All the control lines which connected with plasma power source should be
shielding wire, the shielding layer should be connected ground well;
The control system of CNC cutting machine should be away from the cutting
table, torch cables and cutting torch head, especially the cutting torch heard.
When striking arc, the high frequency spark arc on the cutting torch head may
produce strong space spreading high frequency disturb signal, which may crash
the control system;
There should be shields on the controller of CNC system, and the shielding
layers should be ground connected well;
All the lines connected with CNC controller and cutting table should be shielding
wire (Such as the control wire of step motor ,limit switch etc.), and the shielding
layers should be ground connected well;
The pile of the ground cable should be connected with ground well.
