Device Storage; Connecting The Power - STAMOS S-MMA 200 LT Manual De Instrucciones

• The electrical arc must not be touched.
• 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. Incorrect earthing connection 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.
• 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.
1.5 GASES AND FUMES
PLEASE NOTE: GAS MAY BE LETHAL OR DANGEROUS
TO HUMAN HEALTH!
• Always stay clear of the gas exhaust.
• Ensure proper ventilation of the work space and
avoid gas inhalation.
• Chemical substances (lubricants, solvents) must be
removed from the surfaces of welded details as they
burn and emit toxic smokes under the influence of
temperature.
• Welding galvanised details are permitted only when
efficient ventilation is provided with filtration and
access to fresh air. Zinc fumes are highly toxic, an
intoxication symptom is so-called metal fever

3. OPERATION NOTES
3.1 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
your body.
• The machine must not be installed in rooms with
aggressive environments, high dustiness and near
devices with high electromagnetic field emission.

3.2 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.

3.3 CONNECTING THE POWER

• Connecting 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. Too long wires with
a small cross-section will cause voltage drops and
incorrect operation of the device. The permissible
value of the voltage fluctuation is ± 15% of the rated
value.
• One-phase welders should be connected to the
socket fitted with an earthing prong.
PLEASE NOTE: THE DEVICE MAY ONLY BE USED UPON
CONNECTION TO AN INSTALLMENT WITH A PROPERLY
FUNCTIONING FUSE!

5.1 CONNECTING LEADS
MMA WELDING MODE
1. Use welding mode selection button (6) to select
MMA welding mode (MMA welding mode light (4)
will come on).
2. Connect the return lead to the socket marked with
„+" (7) and tighten the locking nut.
3. Then connect the welding lead to the correct socket,
marked with the „-" (8) sign and tighten the locking
nut. WARNING! Polarisation of the leads may be
different! All polarisation information should be
shown on the packaging supplied by the electrode
manufacturer!
4. Now you can connect the power lead and turn the
power on (10), once the return lead is connected to
the welded element, you can start working.
