striking;
Note: the water and air pressure protection function is for protecting the torch only!
5)
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 shielding layer, the
shielding layer should be metal hose or shielding net pipe made of aluminum or copper, metal materials
which is magnetic conducted cannot 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.

Safety notes
Notes:
Operation strictly accordant with the following steps
Notice
Electric shock may hurt or
even kill man.
Cutting may cause fire or explosion
(Splashes may ignite flammable materials nearby.
Those materials should be 10m away from the
working place.
(Shut off the power during connection
(Do not touch the conducted parts
Fume & dust is harmful.
(Do not breathe in the fume and dust
caused by cutting
(Clean up the oil spot on work piece.
(Keep fresh air in working place
(Fume extraction equipment should be
prepared.
Arc may hurt your eyes and skin.
(Strong arc may hurt your eyes.
(Ultraviolet radiation generated by arc may hurt skin
and eyes. Please wear shielded guard when cutting.
Overheated part may hurt your skin.
(Do not touch the overheated part on
the work piece.
(Do not touch hot cable or torch just by
hands.
Fast moving thing may injure you.
(Do not put your hands or other things into the fan
shield.
(Cover the opened case shell well during cutting
operation.
In case of injury for your skin and eyes, please wear required guards
according to Labor Security and Hygiene rules. Electrode and nozzle should
be replaced only after the cutter is power off.
Operation should proceed according to related Labor and Security
regulations.
