• Install equipment and connect it to ground in accordance with
the operator's manual and national, state and local codes.
• Always check the supply to ground – check and make sure that
the power input to the ground wire is appropriately connected
to the grounding terminal at the disconnection box or that its
plug is appropriately connected to the output receptacle that is
connected to ground. When making these input connections,
first connect the ground conductor and double-check the
connections thereof.
• Keep supply cords free of oil and fat, and protected from hot
metal and sparks.
• Inspect power input cord frequently regarding damage or bare
cable. Replace cord immediately if damaged – a bare cable may
kill you.
• Switch off the whole equipment when you are not using it.
• Do not use cables which are worn-out, damaged, very small-
sized or wrongly connected.
• Do not wrap cables around your body.
• When a grounding clamp is required for a work, make ground
connection using a separate cable.
• Do not touch the electrode when you are in contact with the
work or the grounding circuit or another electrode of a different
machine.
• Do not put into contact two electrode carriers that are connected
to different machines at the same time, because in that case
there will be open-circuit double voltage.
• Use equipment in a well-maintained condition. Repair or replace
damaged parts immediately. Maintain the unit in accordance
with the manual.
• Use safety braces to prevent it from falling down when working
above floor level.
• Keep all panels and covers in place.
• Put the clamp of the work cable in good metal-to-metal contact
to the work or the work table as close as possible to the weld as
it is practical.
• Keep or isolate the grounding clamp such that there is no
contact with any metal or any grounded article.
• Isolate the grounding bracket when not connected to the
workpiece to prevent it from contacting any metal article.
HOT PARTS may cause serious burns.
• Do not touch hot parts with your hand without glove.
• Allow that there is a cooling period before working at the
machine.
• To handle hot parts, use appropriate tools and/or put on heavy
gloves, with insulation for welding and clothing to prevent burns.
SMOKE and GASES may be dangerous.
Welding produces smoke and gases. Breathing in these gases
and smoke may be dangerous for your health.
• Keep your head out of the smoke. Do not breathe in smoke.
• When you are indoors, ventilate the area and/or use forced
local ventilation in front of the arc to withdraw welding smoke
and gases.
• When ventilation is bad use an authorized respirator.
• Read and understand the Data Sheets on Material Safety
(MSDSs) and the manufacturer's instructions regarding
materials, consumables, coatings, cleansers, degreasing
agents.
• Do work within a closed space only if it is well ventilated or
while using an air respirator. Always have near a trained person.
Welding smoke and gases may displace air and reduce oxygen
level causing harm to health or death. Make sure that air for
breathing is safe.
• Do not weld at locations near to operations involving grease,
cleaning or spraying paint. Heat and bolts of the arc may react
with vapors and form strongly irritating and toxic gases.

• Do not weld on coating materials such as galvanized steel,
lead, or cadmium-coated steel, unless the coating has been
removed from the welding area, the area is well ventilated and
while using a respirator with a source of air. Coatings of any
material containing these elements may cause smoke being
emitted when welding.
BOLTS EMITTED BY THE ARC may burn your eyes and skin.
Bolts emitted by the arc of a welding process produce intense
heat and strong ultraviolet rays that may burn eyes and skin.
• Use an authorized welding mask having a lens-filter shade to
protect your face and eyes while welding or looking, cf. safety
standards ANSI Z249.1, Z175, EN379.
• Use authorized safety goggles having lateral protection.
• Use protective screens or barriers to protect others from
flashes, reflections and sparks; alert others not to look at the arc.
• Use protective clothing made of durable, flame-resistant
material (leather, thick cotton or wool) and protection to your feet.
WELDING may cause fire or explosion.
Welding at a closed container such as tanks, drums or tubes
may cause explosion. Sparks may fly from a welding arc. Flying
sparks, the hot workpiece and the hot equipment may cause fire
and burns. Accidental contact of the electrode with metal articles
may cause speaks, explosion, overheating, or fire.
Check and make sure that the area is safe before starting any
welding.
• Remove any inflammable material from within a distance of 11
m of the welding arc. When this is not possible, cover it tightly
with authorized covers.
• Do not weld where sparks may impact on inflammable material.
Protect yourself and others from flying sparks and hot metal.
• Do not weld within closed receptacles such as tanks or drums
or piping unless they have been prepared appropriately in
accordance with AWS F4.1.
• Do not weld where the atmosphere might contain inflammable
dust, gas or vapors from liquids (such as gasoline).
• Connect the work cable to the work area as near as possible to
the place where you will be welding, in order to prevent welding
current from long traveling possibly through unknown parts
causing electrical shock, sparks and fire hazard.
• Do not use welding to deice frozen pipes.
• Remove electrode from the electrode carrier or cut the welding
wire close to the contact pipe when you are not using it.
• Use protective clothing without oil, such as leather gloves,
heavy shirt, closed trousers without patches, high shoes or boots
and a cap.
• Keep away from you any fuel as butane lighters or matches,
before starting to weld.
• After completing work, inspect area to make sure that it is free
of sparks, embers and flames.
• Only use correct fuses or circuit breakers. Do not put ones of
larger size or pass them by one side.
• Follow the regulations in OSHA 1910.252(a) (2) (iv) and NFPA
51B for hot work and have near a person to take care of fire and
an extinguisher.
FLYING METAL OR SLAG may injure eyes
• Welding, grinding, wire brushing or polishing may produce
sparks or flying metal. When welds are cooling down they may
release slag.
• Use authorized safety goggles with lateral guards down to
underneath your mask.
GAS ACCUMULATION may make you sick OR KILL YOU.
• Close shielding gas when not using it.
• Always give ventilation to closed spaces, or use an authorized
respirator that replaces air.
