DESCRIPTION
Thank you for choosing our product! To get the best of your equipment, please read carefully the following.
Plasma Cutter 20 A and cutter 30 A are inverter plasma cutters, portable, single phase, ventilated. They enable to cut in
direct current (DC) steel, stainless steel, aluminium, copper. They work with a single phase 230V input for the plasma
cutter 20 A, a single phase input spread between 85V to 265V for the plasma cutter 30 A They are over-voltage
protected when used on power generators
POWER SUPPLY – START UP
•
This machine is delivered with a 16A plug type EEC7/7. The Plasma cutter 20 A must be plugged on a 230 V (50-
60Hz) socket
with
earth. The plasma cutter 30 A integrates a « Flexible Voltage » system. It has to be on a power
suply variable between 85V and 265V (50 – 60 Hz)
WITH
earth. The absorbed effective current (I1eff) is shown on
the machine, for maximal using conditions.
Check that the main supply and its protections (fuse and/or circuit breaker) are compatible with the required current
in use.
•
To start the equipment, turn on the potentiometer to the desired current position (put the potentiometer on "O" for
standby mode).
•
The machines are protected against overvoltages and pass automatically in standby mode if the supply voltage
exceeds 265V. To point out this defect, the yellow indicator for thermal protection blinks twice then lights off. Normal
operation will resume after thirty seconds when the voltage has returned to its nominal range.
•
This appliance is dedicated for use in industrial environment according to CISPR 11. In a different environment, it can
be difficult to insure the electromagnetic compatibility. Do not use in an environment containing metallic dust
particles which may conduct electricity.
•
These are A-class devices. They are designed to be used in an industrial or professional environment. In a different
environment, it can be difficult to ensure electromagnetic compatibility, due to conducted disturbances as well as
radiation.
•
From 1st December 2010, the new standard EN 60974-10 will be applicable for plasma cutter 20 A: Warning: these
materials do not comply with IEC 61000-3-12. If they are to be connected to a low-voltage mains supply, it is the
responsibility of the user to ensure they can be connected. If necessary consult the operator of your electrical
distribution system.
CUTTING
•
Connect the unit to the electricity network and to the air distribution (PLASMA cutter 30 A only)
•
Adjust the pressure regulator in order to have 2.5 to 4 bar for Plasma Cutter 20 A or 2,5 to 6 bar for Plasma cutter 30
A on the manometer.
•
Switch on the unit.
Plasma cutter 20 A : Above an altitude of 1500m, the atmospheric pressure will be insufficient to operate
the integrated air compressor.
For the plasma cutter 30 A : From 10 A* and to optimize the cutting performances, use the « air flow
tester » supplied with the machine. Process :
-
Press the torch trigger (the arc is appearing).
-
Release, the electrical arc stops but the air continues to flow for about 15 seconds.
-
During this time, put your « air flow tester » at the end of your torch, then adjust your air flow by
placing the ball inbetween the mini/maxi zone.
*nb : For a cutting < 10A, directly adjust to 3 bars.
•
Adjust the current according to the type of metal and the thickness to cut.
