Alignment of the machine torch

Mount the machine torch perpendicular to the material to be cut, use a square to align the torch 
at 0 ° and 90 °, if torch alignment is not possible, check the cutting table for level to obtain a true 
vertical cut�

Operating the machine torch

WARNING 

Plasma arc is generated immediately 

when the CNC start signal is ON

The plasma arc will cut quickly through gloves and skin�  
Make sure the power supply is switched off before changing consumables�

• 

Keep away from the torch tip�

• 

Do not hold the piece that is to be cut and keep your hands away from the cutting path�

• 

Never point the torch toward yourself or toward others�

• 

Never use with the pendant control switch�

Important:

In case of operation of the power supply equipped with 23 m long torch you have to increase 
dynamic gas pressure to value 6�5 bar�
