SAFETY RULES AND GENERAL WARNINGS
INTRODUCTION
CAUTION!
Repairs, maintenance and operation of the unit should be carried out by trained personnel
who are aware of the risks caused by the high voltage needed to operate the plasma cutting
unit. The operator should work in compliance with current standards and abide by all safety
regulations.
CAUTION!
If during the cutting operation a slight electric shock is felt, stop work immediately
and do not use the unit until the fault has been discovered and resolved.

CAUTION!
A further hazard for eyes is the risk of splinters or particles which may be
detached during the cutting operations or during grinding,
brushing or hammering away of the scale.
Always wear goggles or protective shields with transparent lenses during
these operations to prevent splinters or other foreign bodies from entering the eye.
IMPORTANTsafety screens should be installed around the welding area to protect other people,
who may be working in adjacent areas, from the radiation given out by the arc.
FIRE HAZARDS
CAUTION!
Do not cut fuel or lubricant containers even if these are empty.
liquid vapours (such as petrol).
CUTTING FUMES AND GASES
CAUTION!
When halogenated solvents or degreasing agents are present, the material to be cut should
be cleaned properly to prevent the formation of toxic gases. Some chlorinated solvents may
decompose in the presence of the radiation given out by the arc and may generate phosge-
ne gas.
CAUTION!
Never, under any circumstances, look at an electric arc without eye protection.
5
NOISE
CAUTION!
Noise can damage hearing
Wear adequate hearing protection.
BURNS
CAUTION!
Do not point the torch jet at people or foreign bodies.

GENERAL INFORMATION
PLASMA ARC AND BASIC PRINCIPLES FOR THE PERFORMANCE OF PLASMA CUTTING
-
6
1.ON/FF Switch – In the ON position the machine is ready for normal operation. All system
control circuits are activated. OFF position deactivates control circuits.
2.Output Current Knob - Adjusts the cutting current supplied by the machine according to the
thickness of material/speed.
3. Green LED– It blinks for a few seconds to show that capacitors are in charge and that the
unit is getting ready for operation. It turns ON when input voltage is applied within normal
range – blinks slowly when input voltage goes above 260Vac, or below 180Vac.
4. Yellow LED– Turns ON when the thermal protection is activated. Blinks slowly when the
under pressure protection is working (only while working with external air source).
prior to pilot arc ignition. Blinks slowly if cutting arcs not initiated after 3 second pilot arc
ignition.
POWER SUPPLY CONNECTION
Check
that the relevant socket terminal is actually connected to the distribution system grounding.
CONNECTION TO GROUND CABLE

WARNING!: Before starting the cutting operations verify that the parts are properly assembled
by inspecting the head of the torch as shown on paragraph “Torch Maintenance”

NOTE
TORCH CONSUMABLE PARTS SELECTION
Warning: It is extremely important that you read carefully these instructions before choosing
the consumables for your torch. This will prevent damages to the torch and the plasma unit.
WARNING: Wait the torch has completely cooled before replacing torch parts to avoid any
damage to the torch head.

MAINTENANCE
CAUTION!
Never access inside the machine (panel removal) or touch the torch (disassemblage)
without having disconnected power plug.
Any inspection performed under voltage inside the machine or inside the torch may cause
severe electric shocks caused by direct contact with parts under voltage.
