DESCRIPTION
Thank you for choosing our product! To get the best of your equipment, please read carefully the following.
Plasma 20, 20 K and 30 are inverter plasma cutters, portable, single phase, ventilated. They enable to cut in direct
current (DC) steel, stainless steel, aluminium, copper. They are over-voltage protected when used on power generators
(230 V +- 15%)
POWER SUPPLY – START UP
•
This machine is delivered with a 16A plug type EEC7/7. The machine must be plugged on a 230 V (50-60Hz) socket
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. The
machine comes back in normal mode as soon as the supply voltage comes in the 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.
CUTTING
•
Connect the unit to the electricity network and to the air distribution (PLASMA Cutter 20/30 only)
•
Adjust the pressure regulator (PLASMA Cutter 20 and 30 only) in order to have 2.5 to 4 bar for Plasma 20 or 2,5 to 6
bar for Plasma 30 on the manometer.
For the plasma 30 : 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.
•
Switch on the unit.
•
Adjust the current according to the type of metal and the thickness to cut.

•
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.
