• Wear a welding mask to protect eyes
and face when soldering. Assure the mask protective glass
shade is adequate for the soldering process to carry out.
• Wear leather gloves specially made for
welding as well as leather dungarees and gaiter.
• Wear robust clothing and long sleeves made of fire-resistant
materials such as wool or leather.
• Use special screens or curtains to insulate the work place from
passersby, to protect them from sparks, flares and slag originated by
the soldering process.
• Benches and work tables where work pieces shall rest, must have
orifices or slots that can easily let through residues originated by the
soldering process.
• Vapor and gases produced while soldering is
dangerous to your health. Work in well ventilated areas or with
adequate ventilation systems.
• Do not breath in smokes and gasses
emanated from the soldering process. Keep your head away
from vapors.
• If ventilation is poor use an adequate
autonomous breathing device because the gases generated
when soldering may displace air and cause a fatal accident.
• Do not operate the welder near de-greasing
agents, cleaning products or aerosol containers. Heat and
radiation from the welding process may react to those vapors
forming toxic gases.
• Avoid soldering metals covered in lead, zinc or
cadmium. Those materials generate toxic gases. Otherwise,
remove the covering from the welding area. Make sure the work
area is well ventilated or wear an adequate autonomous
breathing device.

ENGLISH
• Verify there is a safe connection for the input and
output cables. They shall be correctly insulated and the connections in
good repair (check and eliminate any possibility of electric shock).
• Double check the welder is plugged to a
reliable ground connection.
• Do not expose the welder to rain or humidity.
• The user shall be insulated from the work piece and
ground connection stepping onto insulating and dry mats.
• For any reason touch the two poles in the welder
circuit (welding stick and work piece).
• Do not try to adjust the welder current when
carrying out a soldering job.
• Connect the ground clamp to the work piece as
close as possible to the welding zone. This prevents the current to flow
long distances and eliminate the possibility of short circuit.
• The work piece shall make contact with the ground
connection clamp before operating the welder. Do not disconnect
until finishing welding because it can lead to an electric discharge and
severe injury.
• Disconnect the welder from the power supply
before carrying any maintenance jobs.
Prevent Electric Shock
• Have always handy a fire extinguisher in
good conditions.
• There shall not be flammable or explosive
materials in the work area (no less than 36’). Do not carry out
soldering jobs where the sparks can reach or fall onto
flammable or explosive materials.

• Risks of electric shock:
An electric shock coming from the soldering electrode may
cause death. Do not weld under rain or snow. Do not touch the
electrode with your bare hands. Do not wear damp or damaged
gloves. Personal protection against electric shock: insulation from the
work piece. Do not open the equipment enclosure. Do not weld on
top of drums or any closed container.
• Soldering sparks may cause explosion
or fire.
• Risks generated by the welding arc:
Radiation coming out from the arc my burn eyes and damage skin.
Wear face mask and protection glasses. Wear hearing
protection and protective clothes that protect skin up to
the neck. Wear full-body protective clothes.
• Risk induced by electro-magnetic fields:
Welding current produces electro-magnetic fields. Do not
use this power source if having a medical implant. Never roll up the
welding cable around your body. Set together and parallel both
welding cables so the fields of each cable counteract.
• Do not use the welder power source to de-ice pipes.
• Never allow unexperienced people to dismount or
regulate the welder.
• Double check that the operator and the welder are
away from the sparks and residues trajectory originated by the
soldering process.
• The welder shall be operated in a place protected from sun and
rain. Away from places where violent vibrations are present.
• Store the welder in a place free of humidity with a range of
temperature from -13 °F to 131 °F
• There shall be a 11.8” space around the welding machine to allow
good ventilation.
• Double check no foreign metal piece is inside the
welder.
• Any problem with the welder that cannot be fixed
by the operator making the adjustments needed for a good welding
job shall be carry out in a Authorized Service
Center. For any reason try to open the welder housing to carry out
any type of maintenance.
• Compressed gas cylinders are widely used in many
welding processes. If not stored, handled, inspected and used adequately
compressed gas cylinders may be fatal. Can explode or turn into missiles,
drawing such force they can even break brick walls.
• Inspect the cylinders. Look for external corrosion,
indentation, lumps, holes of wells. If in doubt about any imperfection
observed is acceptable for those guidelines, stop using the cylinder. Consult
the gas safety page before using it.
• Many compressed gases not only represent a physical
hazard but also dangerous to your health. Be sure you learn the danger to
your health and how to be protected. Always follow the use and handling
caution measures provided in the safety page.
• Never set the cylinders next to heat or flame or where
they can be part of an electric circuit. Do not use them as a source of ground
during the electric welding process.
• Wear safety glasses and a protective mask when
connecting and disconnecting regulators and lines to the cylinder.
• Close the cylinder valve to release pressure before
removing the regulator and when not in use. Cylinders shall be stored with a
visible identification and with the protection valve cap fitted.
• Purge the gas passage before using a new cylinder. Stand
to one side of the cylinder valve, never face up. Open and close the valve
quickly to expel any foreign particles that may be lodged in the valve before
attaching the gas regulator to the cylinder.
• Adjust the pressure appropriately so as not to waste gas. If regulators
indicate extreme pressure, correct immediately.
• Purge the entire system after each use. DO NOT
disconnect equipment with cylinder valves open. • In case of leak, move
cylinder to open area and report immediately
to your Supervisor or Civil Protection.
