Cutting Operation - STAYER WELDING PLASMA Série Mode D'emploi

Compressor of at least 2 horse powers and 50 liters are
recommended.
Install the regulator and additional filter in equipments which
carry them externally. Regulate air input pressure by turning the
upper control. To unlock the control, pull upwards gently. Check
the integrated flow meter if there is sufficient pressure (60 to 80
OSI, equivalent to 4-6 bar). The regulator has an internal safety
valve for cases of overpressure.
For regulating the air pressure, you must rotate regulator 20
(Plasma 40 COM GE) bearing in mind a maximum of 4 bar; you
may increase or reduce the pressure by rotating it sideward;
after having finished, press inwards to secure.

► Second step: INSTALL ELECTRICITIY.
Plasma cutting equipments need sufficient electric supply to
operate. The whole range is prepared to work with correctly
operating generators. Minimum power to be supplied to Plasma
is:

Installing shall be carried out respecting the low voltage
regulation and applicable regulations. The installation must
include a dedicated circuit including 30mA magnetothermal
circuit breaker and differential circuit breaker. The installation
shall provide correct ground connection to the Plasma. The
equipment must be mandatorily connected to a duly approved
ground connection.
It must be borne in mind that three-phase equipments do not use
a neutral. It must be borne in mind that, when sufficient power is
not supplied, the Plasma will work correctly but with the limitation
that it will not be able to cut the whole thickness it could cut.
When the power supplied is small or faulty, the thickness that
may be cut will see itself diminished. In case of doubt, refer to us
or to a professional electrician.
Limiting consumption (optional).
PLASMA 40 COM has limit of maximum consumption of RMS
14A to 230V input when it switches to "LOW".
This is done to protect the installations of low power (16A
magneto) of unforeseen cuts (schools, hospitals, housing)
supply.
"Hi" there are no limitations.

USING THE PLASMA
►Third step: Cutting.
CONNECTION OF THE TORCH AND GROUNDING CLAMP
Connection models PLASMA 40 COM GE and PLASMA 100 T
GE: Connect grounding cable to its DINSE ground connection
12. Erroneous connection is impossible because the connectors
are different. Connect the torch and tighten the cover nut that
seals the compressed air outlet at outlet 11. Connect the red arc
priming cable to connector 13. Connect the connection of switch
of the trigger to the torch at outlet 14.

CUTTING OPERATION

Hold the piece to be cut properly. Connect the grounding clamp
HP
to the piece to be cut. Turn equipment ON by lifting switch 1.
Adjust power with buttons 8 and 9. Indication is shown on display
1/2
4. Set if you wish to pull the trigger in continuous (2 touches) or
discontinuous mode (4 touches) by means of (front digital) button
1/2
10 or (front analogue) button 2. You may check air discharge by
pushing purge button 7.
2 / 3
For cutting, pull trigger 17 (when necessary, unlock it with pin 16)
and point the torch 15 towards the workpiece. Depending on the
model, support the torch by means of a separator sliding spring
or support the plasma outlet nozzle (also called lip) must have
some inclination with respect to the piece in order to facilitate
the discharge of plasma and molten metal. To achieve a higher
speed or to cut a greater thickness, increase amperage and
increase air pressure. The greater the thickness the slower you
must move the torch.
Should you have worked at high power in a continuous manner,
the thermal protection indicator will light up after a certain time
and the equipment will stop cutting; it will only leave the fans in
operating until you will be able to start working again. This is not
a failure but protection.
Welding operation
The model Plasma Multi 40 GE welds with coated electrode and
TIG welding with high frequency priming. To do this, use the
triple selector # 8 to select the desired function and connect the
appropriate accessories (supplied).
4.2. Tool changing.
WARNING: Always connect the DINSE connector as
far as it will go and make sure that the splice with the
cable is in a good condition and that the contact surface
is clean. A bad splice or a dirty connection will result in
a bad performance and make the front panel to become
overheated, fused or burnt.
CONSUMABLES
All models have TRAFIMET torches with consumables
(electrodes, nozzles, diffusers, etc.) that are easy to find at
WELDING or any industrial supply of the sector.
