Ensure the working zone is well ventilated and provision should be made for
suitable local fume extraction system to be in place.
If ventilation is poor, wear an approved air fed welding helmet or respirator.
Read and understand the Material Safety Data Sheets (MSDS’s) and the
manufacturer’s instructions for metals, consumable, coatings, cleaners and
de-greasers.
Do not work in locations near any de-greasing, cleaning or spraying operations.
Be aware that heat and rays of the arc can react with vapours to form highly toxic
and irritating gases.
Arc rays——May injure the eyes and burn the skin.
The arc rays from all processes produce intense, visible and invisible (ultraviolet
and infrared) rays that can burn eyes and skin.
·Wear an approved welding helmet fitted with an appropriate shade of filter lens
to protect your face and eyes when working or watching.
·Wear approved safety glasses with side shields under your helmet.
·Never use broken or faulty welding helmets.
·Always ensure there are adequate protective screens or barriers to protect
others from flash, glare and sparks from the working area.
·Ensure that there are adequate warnings that welding or cutting is taking place.
·Wear suitable protective flame resistant clothing, gloves and footwear.
Precautions against fire and explosion
Avoid causing fires due to sparks and hot waste or molten metal.
Ensure that appropriate fire safety devices are available near the welding and
cutting area.
Remove all flammable and combustible materials from the welding, cutting and
surrounding areas.
Do not weld or cut fuel and lubricant containers, even if empty. These must be
carefully cleaned before they can be welded or cut.
Always allow the welded or cut material to cool before touching it or placing it in
contact with combustible or flammable material.
Do not work in atmospheres with high concentrations of combustible fumes,
flammable gases and dust.
Always check the work area half an hour after cutting to make sure that no fires
have begun.
Take care to avoid accidental contact of electrode to metal objects. This could
cause arcs, explosion, overheating or fire.

Risks due to hot material ·
The process will create hot metal, sparks and drips of molten metal, so it's very
important to ensure the operator is equipped with full PPE and to always ensure
there are adequate protective screens or barriers to protect others from flash,
glare and sparks from the working area. Hot surfaces will create fires and will
burn any exposed skin.
Always protect your eyes and body. Use the correct welding screen and filter
lens and wear full PPE protective clothing.
Do not touch any hot surfaces or parts bare handed.
Always allow hot surfaces and parts to cool down first before touching or moving.
If you are required to move hot parts, ensure you use proper tools and insulated
welding gloves (PPE) to prevent burns to your hands and arms.
Noise——Excessive noise may be harmful to hearing
·Protect your ears by ear shields or other hearing protectors.
·Give warning to nearby personnel that noise may be potentially
hazardous to hearing.
Risks due to magnetic fields
The magnetic fields created by high currents may affect the operation of
pacemakers or electronically controlled medical equipment.
Wearers of vital electronic equipment should consult their physician before
beginning any arc welding, cutting, gouging or spot welding operations.
Do not go near welding equipment with any sensitive electronic equipment as
the magnetic fields may cause damage.
Keep the torch cable and work return cable as close to each other as possible
throughout their length, this can help minimize your exposure to harmful
magnetic fields.
Do not wrap the cables around the body.
Protection from moving parts
When the machine is in operation keep away from moving parts such as motors
and fans.
Moving parts, such as the fan, may cut fingers and hands and snag garments.
Protections and coverings may be removed for maintenance and controls only
by qualified personnel after first disconnecting the power supply cable.
Replace the coverings and protections and close all doors when the intervention
is finished and before starting the equipment.
Take care to avoid getting fingers trapped when loading and feeding wire during
set up and operation.
When feeding wire be careful to avoid pointing it at other people or towards your
body.
Always ensure machine covers and protective devices are in operation.

Troubleshooting
Before the machines are dispatched from the factory, they have already been
checked thoroughly. The machine should not be tampered with or altered.
Maintenance must be carried out carefully. If any wire becomes loose or is
misplaced, it maybe potentially dangerous to user!
Only professional maintenance personnel should repair the machine!
Ensure the power is disconnected before working on the machine. Always wait 5
minutes after power switch off before removing the panels.
