1_INTRODUCTION
The present unit is a MIG/MAG equipment for continuous
wire metal, coated electrode and TIG process welding.
Technologically, the STAYER WELDING equipment is a
power supply source for high-frequency power transfer,
managed by smart control logic.
Compared to the traditional technology, based on transformers
operating at the 50Hz public grid frequency, the STAYER
WELDING Inverter technology presents a higher power
density per weight unit, an increased power saving and the
possibility of an automatic, precise and instantaneous control
of all welding parameters.
As a result, you will easily produce a better weld with lower-
consumption and a weightless equipment compared to the
equivalent traditional ones based on heavy transformers.
2_SAFETY INSTRUCTIONS
CAREFULLY READ THE FOLLOWING
INSTRUCTIONS
• Make sure you read and understand the user's manual
before using or operating the equipment.
• Only use the genuine components of the manufacturer.
SYMBOLS USAGE
Indicates a hazardous situation that, if not avoided,
will result in serious injury or death. The possible

explained in the text.

ARC WELDING DANGER
Only qualified users should install, operate, maintain
and repair this unit.
While operating, it must be kept away from people,
specially kids.
An electric shock may kill you.
Touching electric live-load pieces may cause severe burns
or a fatal electric-shock. The electrode and work circuit
become 'electrically hot' whenever the machine output is on.
Both the output and the inner circuits are also 'electrically
hot' when the machine is on. While welding with automatic
or semiautomatic equipment, the wire, coil, the chassis that
holds the feed rollers and all the metal pieces touching the
welding wire, are 'electrically hot'. An incorrectly installed or
not-earthed equipment is a various serious danger.
• Do not touch 'electrically hot' pieces
• Use dry and well-insulated gloves with no gaps and whole-
body protection
• You must isolate yourself from the work and the ground
contact by using carpets or big enough covers, made of
non-conductive materials in order to prevent any kind of
physical contact with them
• Do not use the AC output in humid areas, when restricted
motion, or if there is a fall risk
• Use CA output only if the welding procedure requires it
• If the CA is required, use a remote control if available in
your unit
• Additional safety precautions are required when any of
the following dangerous electric conditions are present:
in humid places or while wearing wet clothes, in metal
structures such as floor, grids or scaffoldings, when the
user is in tight positions as seated, kneeled, lying down
or when there is a high risk of having an avoidable or
accidental contact with the ground or workpiece.
• Disconnect the input power or completely stop the unit
before installing or servicing it.
• Properly install and connect the unit to the ground according
to the manual and the national, state and local codes.
• Always verify the ground supply. Check and make sure
the power supply input ground wire is properly plugged
to the disconnection box ground terminal, or its plug is
appropriately connected to the ground-plugged output
receptacle. While plugging output connections, firstly plug
the ground conductor and double check its connections.
• Keep the seams and wires dry with no oil or grease stains.
Protect them from hot metal and sparks.
• Frequently inspect the current seam output for damages or
bare wire. Immediately replace the seam if it is damaged –
A bare wire can kill you.
• Turn off the equipment if it is not being used.
• Do not use wasted, damaged, small-sized or bad connected
cables.
• Do not wrap your body with the cables.
• If an earth clamp is needed at work, make the grounding
connection with a separated cable.
• Do not touch the electrode if you are already touching the
grounding circuit, work circuit or another electrode from a
different equipment.
• Do not bring two electrode holders together while being
connected to different units at the same time or there will
be a double current open circuit.
• Use a well-maintained equipment. Repair or replace all
the damaged pieces. Maintain the unit according to the
manual.
• Use safety straps to prevent the machine from falling if you
are working higher than the floor height.
• Keep all the panels and covers on their place.
• Put the clamp of the working cable with a good metal-to-
metal contact to the working cable or the work itself, close
to the weld for it to be practical.
• Save or isolate the clamp when it is not connected to the
working place so there will be no contact with any metal or
any other ground object.
• ·solate the grounding clam when it is not connected to
the working piece in order to avoid contact with any metal
object.
HOT COMPONENTS can cause severe burns
• Do not touch hot components with bare hands. Use
adequate gloves and allow some time for the equipment to
cool itself before using it again.
• To operate with hot components, use appropriate tools and
wear heavy gloves with welding-isolating and adequate
clothes to prevent burns.
SMOKE and GASES can be dangerous
Welding produces smoke and gases. Breathing those can be
dangerous for your health.
• Keep your head out of the smoke. Do not breath it.
• If you are working indoors, make sure you ventilate the
area and use forced local ventilation before the arc to take
the welding smoke and gases away.
• If the ventilation is bad, use an approved air respirator
• Make sure you read and understand all the Material Safety
