3.5. GASES AND FUMES
PLEASE NOTE! GAS MAY BE LETHAL OR DANGEROUS
TO HUMAN HEALTH.
•
Always keep a certain distance from the gas outlet
•
When welding, ensure good ventilation. Avoid
inhaling the gas.
•
Chemical substances (lubricants, solvents) must be
removed from the surfaces of welded objects as they
burn and emit toxic smokes under the influence of
high temperatures.
•
Welding galvanised objects is permitted only when
efficient ventilation is provided with filtration and
access to fresh air. Zinc fumes are very toxic, an
intoxication symptom is the socalled zinc fever.
4. OPERATION
4.1. GENERAL NOTES
•
The device must be applied according to its purpose,
with observance of OHS regulations and restrictions
resulting from data included in the rating plate (IP
level, operation cycle, supply voltage, etc.).
•
The machine must not be opened, as it will cause
warranty loss and, in addition, exploding, unshielded
elements can cause serious injuries.
•
The producer does not bear any responsibility for
technical changes in the device or material losses
caused by the introduction of the said changes.
•
In case of incorrect device operation, contact the
service centre.
•
Louvers must not be shielded – the welder must
be positioned at 30 cm distance from the objects
surrounding it.
•
The welder must not be kept under your arm or near
your body.
•
The machine must not be installed in rooms with
aggressive environments, high dustiness and near
devices with high electromagnetic field emission.
4.2. DEVICE STORAGE
•
The machine must be protected against water and
moisture.
•
The welder must not be positioned on heated
surfaces.
•
The device must be stored in a dry and clean room.
4.3. CONNECTING THE DEVICE
4.3.1 Connecting the power
•
Connecting the device must be performed by
a qualified person. In addition, a person with the
required qualifications should check if the earthing
or electrical installation with protection system is in
line with the safety regulations and if they operate
correctly.
•
The device must be placed near the work station.
•
Connection of excessively long conduits to the
machine must be avoided.
•
One-phase welders should be connected to the
socket fitted with an earthing prong.
•
Welders powered from a 3-Phase network are
delivered without a plug, the plug must be obtained
independently and installation should be assigned to
a qualified person.
PLEASE NOTE! THE DEVICE MAY ONLY BE USED UPON
CONNECTION TO AN INSTALLMENT WITH A PROPERLY
FUNCTIONING FUSE.

2T – press this button on the burner to start the
metal welding process, release this button to end
this process.
4T – press this button on the burner to start the
metal welding process, releasing this button does
not end this process. Press and release this button
again to end the metal welding process.
4.
Display
Welding machine control panel control lights:
HOT START – this function makes it easier to initiate an
electric arc, by momentarily increasing the welding current
the moment the electric arc is discharged. Once discharged,
the welding current returns to its pre-set value (0-10).
A – WELDING CURRENT, (5-200 A).
10 10
ARC FORCE – this function stabilises the electric arc under
length changes (0-10).
MMA – covered electrode welding.
LIFT – (TIG LIFT) tungsten inert gas welding, where the
electrode has to be rub / touch the welded material in
order to obtain an electric arc.
HP – (TIG HF – high frequency) tungsten inert gas welding,
VIII
where electrode discharge is achieved using an ioniser
installed within the welder.

GAS PRE–FLOW – gas pre-flow time.
2.
STARTING AMP. (only in 4T mode) – value of output
current upon arc striking.
3.
CURRENT UP SLOPE – time over which the value of
the output current increases from the initial current
value to the welding current value.
4.
WELDING CURRENT / PEAK AMP in PULS mode.
5.
BASE AMP. current sustaining the arch in the PULS
mode.
6.
CURRENT VALUE DECREASE – The time it takes
for the current value to decrease from the welding
current value to the final current value
7.
CURRENT DOWN SLOPE (only in 4T mode) – time
over which the output current value decreases from
the welding current value to the initial current value.
8.
GAS POST–FLOW – gas post-flow time Function used
in order to cool down the weld and to protect it
against oxidation.
9.
PULSE WIDTH – this is the relation of the impulse
duration to the impulse period. Parameter selected
in TIG PULSE mode.
10.
PULSE FREQ – impulse frequency during PULS mode
welding.
11.
NO PULSE MODE – DC welding.
12.
PULSE TIG MODE – this function makes it possible
to reduce the quantity of heat which the material is
exposed to.
The display also shows lights indicating the units for the
displayed parameter.
The „

CABLE CONNECTIONS
MMA WELDING MODE
1.
Use button (2) to select MMA welding mode.
2.
Connect the return lead to the correct socket,
marked with the number V on the diagram and
tighten the locking nut.
3.
Then connect the welding lead to the correct socket,
