Device Storage; Connecting The Device - STAMOS S-MULTI 300 Manuel D'utilisation

• Electrical power must be shut down prior to cleaning
or electrode replacement.
• It must be checked if the earthing cable is properly
connected or the pin is correctly connected to the
earthed socket. Incorrectly connecting the earthing
can cause life or health hazard.
• The power cables must be regularly checked for
damage or lack of insulation. Damaged cables must
be replaced. Negligent insulation repair can cause
death or serious injury.
• The device must be turned off when it is not in use.
• The cable mustn't be wrapped around the body.
• A welded object must be properly grounded.
• Only equipment in good condition can be used.
• Damaged device elements must be repaired or
replaced. Safety belts must be used when working
at height.
• All fittings 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.
• Attach the ground cable to the part being welded
or as close to it as possible (e.g. to the 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.
3.6. 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
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 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.
• Never use welding equipment to defrost pipes.
EN

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
• The connection of the device must be performer 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.
• Connecting 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.
4.3.2 CONNECTING GAS
• Gas tanks must be placed far from the welded object
and be protected against falling.
• Gas connector of the welder must be connected with
the tank or gas installation by means of the correct
pipe and regulator with gas flow regulation. Please
note! Connection of line regulators to the tank and
the other way round is prohibited. Such a change can
result in regulator damage and serious injuries.
• Economical gas use extends the welding time.
4.3.3 PRECAUTIONS TO PREVENT ROLL-OVER
• When lifting the device with a forklift, secure the power
cord so that it cannot cause the device to tip over.
• When using a crane to lift the machine, attach the
rope to the hooks at an angle of no more than 15 °
to the vertical.
• Before lifting the device, dismantle the gas cylinder
and disconnect the device from the power supply.
• When rolling the device on a horizontal surface, the
gas cylinder must be properly secured, e.g., with
a strap or chain.

Assembly of the reel with welding wire
• Open the device side cover.
• Position the spool with the welding wire on the axle.
The spool hole should fit the size of the spool holder.
• Select the wire path according to the diameter of the
selected welding wire.
EN
• The welding wire spool should rotate counter-
clockwise. Bent wire may become jammed; cut off
the bent parts of the wire.
• Loosen the screw of the wire clamping roller, insert
the welding wire into the wire guide, adjust the
wire clamping roller to prevent slipping (too much
pressure is also not desirable as it will deform the
wire and obstruct the feed).
• Install the cable together with the torch in the EURO
socket. Passing the wire through the torch may
require disassembly of the nozzle and the current tip.
If parts of the device are packaged separately, assemble
them as follows.
1. Pass the wheel axle [C] through the base hole of
the detachable undercarriage [D] using 2 screws as
shown in Figure 1.
2. Attach the left [A] and right [B] bracket to the base
of the detachable undercarriage with 2 screws as
shown in Figure 1.
3. Attach the wheels [E] to the axle and secure the
connection using the washers [F] and the cotter pins
[G] as shown in Figure 2.
