Connect the earth clamp on a stripped zone of the piece to cut.
•
The PLASMA cutting machine is equipped with pilot arc system. This system allows starting the arc without touching
the piece to cut. You have 2 ways to cut your piece :
▪ Press on the trigger
pilot arc formation
cutting by contact with the piece.
▪ Contact with the piece
press on the trigger
immediate cutting
•
During the cutting, make sure to maintain the contact between the nozzle and the piece to cut.
DUTY CYCLE
The machines described have an output characteristic of 'constant current' type. The duty cycle are indicated in the
table below according to EN60974-1 Norm.

MAINTENANCE
•
Refer all servicing to qualified personnel.
•
Disconnect the generator and wait until the ventilator stopped before working on the unit. Inside the device,
voltages and current are dangerous.
•
We suggest removing the steel cover 2 or 3 times a year and remove any excess dust. Let check the electrical
connections (with an insulated tool) and the insulations by qualified personnel.
•
Regularly control the state of the cord. If this supply cable is damaged, it must be replaced by the manufacturer,
its after sales service or a similarly qualified technician to avoid any danger.
ADVICE
•
Leave the inlets free to allow in/out air circulation.
SECURITY
Cutting can be dangerous and lead to serious or even fatal injuries. Protect yourself and protect the
others.
Respect the following warnings:
Arc rays :
Protect yourself thanks to a welding helmet in compliance with EN175 equiped with filters in
compliance with EN 169 or EN 379. Inform and protect by the same means any people in the
welding environment.
Rain, steam,
The working environment must be clean (degree of pollution ≤ 3) and protected
humidity :
against rain. Put the appliance on an even place and at least at one meter from the parts to
be cut. Do not use them under rain or snow.
Electric shocks :
This appliance may only be use with a 230V monophase supply and must be earthed.
Moving :
Do not underestimate the weight of the apparatus. Do not carry it over people or things. Do
not drop it. Do not set it brutally
Burns :
Wear protective or fire-proof clothing (overalls, jeans).
Use some welder gloves and a fire-proof apron.
Protect the others by installing non flammable protection wall, or prevent the
others from looking at the arc and make them keep a sufficient distance
Fire risks:
Suppress all flammable products from the working area. Do not work near flammable gas.
Smokes:
Do not inhale gas or welding smokes. If indoors ventilate the area well and/or use local
extraction ventilation equipment to remove fumes and gases.
Extraprecautions:
Any cutting operation:
