- 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 rst disconnecting
and removing all interconnection and power supply cables and
piping.
- Do not use the handle to hang the plasma cutting system.
2. INTRODUCTION AND GENERAL DESCRIPTION
Plasma cutting system with compressed air 3-phase, with fan. Used for
fast cutting without deformation on steel, stainless steel, galvanized steel,
aluminium, copper, brass etc. The cutting cycle is enabled by a pilot arc.
MAIN CHARACTERISTICS
- Adjusts the cutting current.
- Torch voltage control device.
- Air pressure, torch short-circuit control device.
- Thermostatic safeguard.
- Air pressure display.
- Torch cooling control.
- Overvoltage, undervoltage, phase failure.
- Remote control connector.
STANDARD ACCESSORIES
- Plasma cutting torch.
- Compressed air connection tting kit.
OPTIONAL ACCESSORIES
- Spare electrodes-nozzles kit.
- High air ow torch.
- Spare electrodes-nozzles kit for high air ow torch.
- Gouging kit.
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- Symbol referring to the internal structure of the machine.
3- Symbol referring to plasma cutting procedure.
4- 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).
5- Symbol indicating the main power supply:
1~: single phase alternating voltage
3~: 3-phase alternating voltage
6- Casing protection rating.
7- Technical speci cations 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
: E ective current supplied
1e
8- 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.
9- Machine serial number (indispensable identi cation when asking for
technical assistance, ordering spare parts or discovering the origin of
the product).
10-
: Size of delayed action fuses to be provided to protect the
power line.
Fig. A
11- 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 gures; the exact values of the technical speci cations
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 tted to the head of the torch, or if it is not
tted correctly.
2 - Return cable.
3 - Control panel.
CONTROL PANEL (Fig. C)
1 - Encoder and Button
Encoder function:
Allows current adjustment in any operating mode.
Button function:
Allows setting of the unit of measurement adopted by the pressure
probe in any operating mode.
2 - Mode selecting button
Allows selection of the following modes (Fig. D):
CUTTING
Standard operating mode.
GRID CUTTING
Arc cutting mode maintained even when it is not transferred to the
piece.
BLOCKED CUTTING
Similar to cutting mode except that as soon as the cutting arc is
established, the torch button can be released. Cutting is interrupted
by pressing the torch button again.
GOUGING
Gouging mode, suitable for use with the torch and GOUGING
consumables.
3 - AIR button
When this button is pressed, air output will continue from the torch
