• Be alert to that, when welding a ceiling, floor, wall or any kind
of separation, heat may cause fire at the hidden part which
cannot be seen.
• 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 possibly traveling through unknown
parts causing electrical shock, sparks and fire hazard.
• Do not use welding to deice frozen pipes.
• Remove the 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 any fuel as butane lighters or matches away from you,
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 a person near 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.
► MAGNETIC FIELDS may affect implanted medical devices.
• Persons using pace makers or other implanted medical
devices must stay away.
• Persons using implanted medical devices must consult
their doctor and the manufacturer of the apparatus before
approaching arc welding, point welding, slotting, plasma
cutting, or induction heating operations.
► NOISE may injure your ear.
• The noise of some processes or equipment may harm your
ear. Use authorized ear protection when the level of noise is
very high or above 75 dBa.
► THE CYLINDERS may burst when they have failures.
Cylinders containing shielding gas contain that gas under high
pressure. The cylinders may burst when they have failures. As
the cylinders are usually part of the welding process, always
treat them with care.
• Protect pressurized gas-containing cylinders from excessive
heat, mechanical impacts, physical damage, slag, flames,
sparks and arcs.
• Install and secure the cylinders in a vertical position securing
them to a stationary support or a cylinder holder to prevent
them from falling down or falling over.
• Keep cylinders far away from electric or welding circuits.
• Never wrap the welding torch about a gas cylinder.
• Never allow an electrode to contact any cylinder.
• Never weld on a pressurized cylinder; there will be an explosion.
• Use correct shielding gas only, as well as regulators, hoses
and connections designed for the specific application; maintain
them, the same as the parts, in a good condition.
• Always keep your face away from a valve outlet except when
operating the cylinder valve.
• Keep the protective cover in place over the valve except when
the cylinder is in use or connected for being used.
• Use the correct equipment, correct procedures and a sufficient
number of persons to lift and move the cylinders.
• Read and follow the instructions regarding compressed gas
cylinders, associated equipment and the publication of the
Compressed Gas Association (CGP) P-1 as well as local
regulations.
► FIRE OR EXPLOSION hazard.
• Do not place the unit on, over or close to combustible surfaces.
• Do not install the unit close to inflammable articles.
• Do not overcharge your building’s wiring – make sure that your
power supply system is suitable in size, capacity and protected
to comply with the requirements of this unit.
► A DOWN-FALLING UNIT may cause injuries.
• With heavy equipment, do use the lifting eye only for lifting the
unit, NOT the wheel train, gas cylinders or other accessories.
• Use equipment having a suitable capacity to lift the unit.
• When using a fork lift, make sure that the tines of the fork lift are
sufficiently long to extend beyond the opposite side of the unit.
► OVERUSE may cause OVERHEATING OF THE EQUIPMENT.
• Allow for a cooling period, follow the nominal working cycle.
• Reduce the working cycle or current before welding again.
• Do not block or filter the airflow to the unit.
