- IMPROPER USE: it is dangerous to use the plasma cutting system
for any work other than that for which has been designed.
- Never lift the plasma cutting system without first disconnecting
and removing all interconnection and power supply cables and
piping.
- RISK OF BURNS
Some parts of the plasma cutting system (torch) and adjacent
areas can reach temperatures over 65°C: adequate protective
clothing must be worn.
Allow the just cut workpiece to cool before touching it!
- MISUSE: it is dangerous for more than one operator to
simultaneously use the plasma cutting system.
- Do not use the handle to hang the plasma cutting system.
ENVIRONMENTAL CONDITIONS (EN 60974-1)
- Use the machine with the following environmental conditions
only:
• ambient temperature between -10°C and 40°C;
• relative humidity of the air not exceeding 50% at 40°C;
• relative humidity of the air not exceeding 90% at 20°C;
• The surrounding air must be free of dust, acid, gas or corrosive
substances, etc.
STORAGE
- Position the machine and its accessories (with or without
packaging) in closed premises.
- The ambient temperature must be between -20°C and 55°C.
If the machine is planned with liquid cooling and an ambient
temperature under 0°C: use the anti-freeze liquid suggested by the
manufacturer or completely empty the hydraulic circuit and the tank
of liquid.
Always use adequate measures to protect the machine from
humidity, dirt and corrosion.
DISPOSAL
Do not dispose of this machine as normal household waste at the end
of its life cycle.
The user is responsible for disposing of this electrical equipment in
collection points designated for disposal and recycling of electrical
equipment or contact the shop where you purchased the product.
This provision only refers to disposal of the equipment within the
European Union (WEEE).

3. TECHNICAL INFORMATION
DATA PLATE
The most important information regarding use and performance of the
plasma cutting system is summarised on the rating plate and has the
following meanings:
1- EUROPEAN standard of reference, for safety and construction of arc
welding and plasma cutting machines.
2- manufacturer's name and address.
3- product model.
4- Symbol referring to the internal structure of the machine.
5- Symbol referring to plasma cutting procedure.
6- S symbol: indicates that cutting operations may be carried out in
environments with heightened risk of electric shock (e.g. close to
large metal masses).
7- Symbol indicating the main power supply:
1~: single phase alternating voltage
3~: 3-phase alternating voltage
8- Casing protection rating.
9- Technical specifications for main power supply:
- U : Alternating voltage and frequency of power supply to the
1
machine (allowed limits ±10%):
- I
: Maximum current absorbed by the line.
1 max
- I : Effective current supplied
1 eff
10- Performance of cutting circuit:
- U : maximum no-load voltage (open cutting circuit).
0
- I /U : Current and corresponding normalized voltage that the
2 2
machine is able to supply during cutting.
- X : Duty cycle: indicates the time for which the machine is
able to supply the corresponding current (same column). It is
expressed in %, based on a 10 min. cycle (e.g. 60% = 6 minutes
work, 4 minutes pause; and so on).
If the usage factors (on the plate, referring to a 40°C
environment) are exceeded the thermal cutout will trigger (the
machine will remain in standby until its temperature returns
within the allowed limits).
- A/V-A/V : indicates the range over which the cutting current
may be adjusted (minimum - maximum) at the corresponding
arc voltage.
11- Machine serial number (indispensable identification when asking for
technical assistance, ordering spare parts or discovering the origin of
the product).
12-
: Size of delayed action fuses to be provided to protect the
power line.
13- Symbols referring to safety standards, the meaning of which is
explained in chapter 1 "General safety instructions for plasma arc
cutting".
Note: The data plate shown here is an example for explaining the meaning
of the symbols and figures; the exact values of the technical specifications
for your plasma cutting system must be read directly on the rating plate
of the machine itself.
OTHER TECHNICAL INFORMATION:
- POWER SOURCE: see table 1 (TAB.1)
- TORCH: see table 2 (TAB.2)
The weight of the machine is given in table 1 (TAB. 1).
4. DESCRIPTION OF THE PLASMA CUTTING SYSTEM
Control devices, adjustment and connection
POWER SOURCE (Fig. B)
1 - Torch with direct or control panel connection.
- The torch button is the only control device that can be used to start
and stop cutting operations.
- When the button is released the cycle will cease instantaneously,
whatever stage it is at, and only the cooling air (post-air) will be kept
on.
- Accidental manoeuvres: the cycle will only be allowed to start if the
button is pressed for a preset minimum interval of time.
- Electrical safety: button operation is disabled if the insulating
nozzle-holder is NOT fitted to the head of the torch, or if it is not
fitted correctly.
2 - Return cable.
3 - Control panel.
