4.3.- Adjusting operations
All
machines of contain a complex electronic
system and are provided ex works in a completely calibrated
status, so that the user is not authorized to manipulate it for
reasons of efficiency and safety. In the case of any doubt
concerning bad functioning please contact your dealer or our
customer service system.

4.4.- Limits of the size of the work piece
The main restriction on the size of the piece to be welded is the
thickness thereof that it limited by the power of the equipment. The
higher power is, you will be able to make correct welds (with an
adequate penetration of the weld bead) in pieces of major
thickness. The following table may serve as an orientation
4.5.- General instructions for use
Before starting, make sure that you read, understand and apply
the safety instructions and the rest of the instructions included in
the present manual.
Hereinafter you will find a series of general indications that will
allow you to initiate yourself in the world of welding and to start to
work efficiently. Instruction on the rudiments of welding by means
of coated electrodes with a relatively moderate level of execution,
having a relatively higher difficulty is provided in the present
manual. Please take into account that, at a professional level,
welding is a qualified and specialized activity. Please refer to
specialized books and regulated professional training courses for
more information.

1.- Welding with coated electrode
In this class of electric arc welding, the electrode itself produced
the heat in the form of an electric arc, the protection ambient and
improves the weld coating and the filler metal when the metal core
of the electrode fuses in accordance with the weld being made.
You must choose the electrode (size and type) that is adequate for
the kind of work to be carried out. The electrode we recommend
due to its mean characteristic, validity or the major part of works
and for being the easiest one to find, is the E-6013 electrode
commonly known as "rutile electrode".
STAYER WELDING
2.
Arrange cables to one side and away from the operator.
3.
Do not coil or drape cables around your body.
4.
Keep welding power source and cables as far away from opera-
tor as practical.
5.
Connect work clamp to workpiece as close to the weld as possi-
ble.
3. - Startup instructions
3.1.-Placement
The machine must be placed in a dry, ventilated area and at a
distance of at least 15 cm away from any wall. The equipment may
skid on surfaces with inclinations of more than 3O so that ii must
always compulsorily be placed on an even and dry surface. For
placement on surfaces having a higher slope, please secure the
machine with chains or belts.
3.2.- Mounting
The equipment must be mounted respecting its environmental
limits and placing it adequately.
3.3.- Connection to the grid
The equipment is powered by means of the series-provided cable
and connector through a differential switch and a connector slow-
feature electromagnet of an electrical strength according to the
table of technical features. Any connection must have a regulatory
connection to earth and comply with all domestic regulations on
electricity.
In the case of a connection to an electric generator, the power
needs as indicated in the technical features are to be observed. It
must be taken into account that an equipment can operate with a
generator with a power that is lower than the indicated one with the
limitation that it is to be used at a maximum electrical strength that
is lower than the nominal one.
3.4.- Limitation of environmental conditions
The equipment must be installed respecting the IP21
classification thereof; this means that the equipment is protected
at the most against the vertical fall of water drops and access to
dangerous parts with a finger and against solid bodies of 12.5 mm
and larger ones.
The equipment is prepared for working within the temperature
range of -15ºC to 70ºC, taking into account the limitation of its drop
in performance (duty cycle) as of temperatures higher than 40ºC.
4.- Operating instructions
4.1.- Placement and tests
All
STAYER WELDING
machines of the MMA series must be
handled by means of the belt handle which is enabled for
transport. A free space of at least 15 cm must be provided around
the equipment, and free circulation of air must be secured for a
correct heat dissipation. Before each work, the good status and
correct tightening of each of the external elements of the
equipment must be verified: power supply plug, cable, carpentry
of the casing and connection terminals and switches.
4.2.- Changing tools
All
STAYER WELDING
machines of the MMA series have a
DINSE half-inch or 3/8 inch quick connector for the welding
cables. For removing or putting the connector it is sufficient to turn
the connector a fourth of a turn leftward or rightward.

In fire and electrical shock increment risk places as
close to flammable and explosive stuff, height, reduced
freedom of movement, physical contact with
conductors, hot ambiences that reduces electrical
resistance of human skin and devices please
compulsory observe the local and national legal
regulations.
!
Always turn the DINSE connector to the limit and make
sure that the junction with the cable is in a good status
and that the contact surface is clean. A bad junction or a
dirty junction lead to a bad yield and will cause the front
panel to heat up, fuse or burn.
