Device Storage; Connecting The Power - Expondo STAMOS S-MULTI 250M Manuel D'utilisation

• All fitting and safety elements must be stored in one place.
• From the moment of turning on the release, the handle end must be kept away from the body.
• The chassis ground must be mounted to the welded element or as close to it as possible (e.g. to a work table).
THE DEVICE CAN STILL BE UNDER VOLTAGE UPON FEEDER DISCONNECTION!
• The voltage in the input capacitor must be checked upon turning off the device and disconnecting it from the power
source. One must make sure that the voltage value is equal to zero. Otherwise, the device elements must not be
touched.
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 inhalation of 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 temperature.
• The welding of 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 so called 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 objects surrounding it.
• The welder must not be kept under your arm or near to 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

• Connection of the device must be performed by a qualified person. In addition, a person with 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.

1 MMA /TIG /MIG mode switch
Control lights:
• ERROR INDICATOR = The indicator lights in the following two situations:
a) If the machine has malfunctioned and cannot be operated.
b) If the cutting device has exceeded the standard working time, the protection mode is initiated and the
machine will stop functioning. This means that the machine is now being cooled in order to be able to restore
2. the temperature control again after the device has overheated. Therefore, the machine is stopped. During
this process, the red warning light on the front panel lights up. In this case it is not necessary to unplug the
device. The ventilation system may be left on in order to enhance the cooling of the machine. When the red
light goes dark, this means that the temperature is set to the normal level and the unit can be put back into
operation.
• MIG/TIG/MMA mode indicator lights.
3. Welding wire feeder switch: WIRE FEED – feeder inside the device / SPOOL GUN – spool gun type feeder.
4. Foot pedal operating mode switch
5. Voltage display
Inductance switch:

7. Current display
Inductance adjustment:
8. • narrow range of inductance adjustment –inductance 1-10
• wide range of inductance adjustment – inductance 1-20
2T/4T SWITCH:
2T – press this button on the burner to start the metal welding/cutting process, release this button to end
9. this process.
4T – press this button on the burner to start the metal welding/cutting process, releasing this button does
not end this process. Press and release this button again to end the metal welding/cutting process

CABLE CONNECTIONS:
MMA WELDING MODE
1. Set the switch (1) to MMA welding mode.
2. Connect the mass cable to the socket marked with „+" (13).
3. Then connect the cable with MMA electrode holder to socket marked with the „-" sign (12). WARNING! The
