2. Installation

Unpacking

Check the packaging for any signs of damage. Carefully remove the machine and retain the packaging 
until the installation is complete.

Positioning of the machine

Place the machine on a firm, dry and level surface. Where possible, do not allow dust or other impurities 
to enter the machines cooling air flow. Preferably site the machine above floor level; for example on a 
suitable carriage unit.
Notes for positioning the machine
•   The surface inclination should not exceed 15 degrees.
•   Ensure the free circulation of the cooling air. There must be at least 20cm of free space in front 
   of and behind the machine for cooling air to circulate.
•   Protect the machine against damp and direct sunlight.

NOTE!  

The machine should not be operated in heavy rain as the protection class of the machine, IP23S, 

allows for limited outside use.

NOTE! 

 Never aim metallic grinding spray/

sparks towards the equipment.

Input connection

Before connecting the machine you should 
ensure that the correct supply is available. 
Details of the machine requirements can 
be found on the data plate of the machine 
or in the technical parameters shown in 
the manual. The equipment should be 
connected by a suitably qualified competent 
person. Always ensure the equipment has 
a proper grounding. Never connect the 
machine to the mains supply with the 
panels removed. 

Working connections 

Connect the cutting torch, earth cable and 
regulator, according to the connection 
diagram. The gas supply can be either air 
or nitrogen. A high pressure regulator must 
be used on either type of gas and must be 
capable of delivering  155 l/min at a pressure 
of 72 psi ( 5.0 bar) to the machine. Ensure the 
air supply is dry and oil free.
