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 inner ear.
• The noise of some processes or equipment may harm your
inner 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
handle 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 collapsing.
• 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 at 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 proceedings 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 UNIT THAT FALLS DOWN 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.
FLYING SPARKS may cause injuries.
• Use a face guard to protect your eyes and face.
• Shape the tungsten electrode only in a grinder with appropriate
guards at a safe location using necessary protection for your
face, hands and body.
• Sparks may cause fire – keep inflammables far away.

THE WELDING WIRE may cause you injuries.
• Do not press the trigger of the torch until receiving these
instructions.
• Do not point the tip of the torch towards any point of your body,
any other persons or any metal object when passing the wire.
MOVING PARTS may injure.
• Keep away from any moving parts such as fans.
• Keep any doors, panels, lids and guards closed and in place.
• Achieve that only qualified persons remove doors, panels, lids
and guards to provide maintenance as necessary.
• Reinstall doors, panels, lids and guards after having completed
maintenance and before reconnecting input power.
HIGH FREQUENCY RADIATION may cause interferences.
• High frequency radiation (H.F.) may interfere with radio
navigation, safety services, computers and communication
equipment.
• Make sure that only qualified persons familiarized with
electronic equipment install the equipment. The user takes
responsibility for having a trained electrician who will correct any
problem caused by the installation soon.
• Make sure that the installation receives regular checking and
maintenance.
• Keep doors and panels of a high frequency source completely
shut, keep the distance of the spark at the contact points in its
correct fixation and is grounded and protects countercurrent to
minimize the possibility of interference.
ARC WELDING may cause interference.
• Electromagnetic energy may interfere with sensitive electronic
equipment such as computers or computer-driven equipment
such as industrial robots.
• Make sure that any equipment within the welding area is
electromagnetically compatible.
• To reduce possible interference, keep welding cables as short
as possible, as close together as possible or, on the floor, if
possible.
• Place your welding operation at a distance of at least 100
meters away from any electronically sensitive equipment.
• Make sure that the welding machine is installed and grounded
in accordance with this manual.
• If there still is interference, the operator has to take extraordinary
measures, such as moving the welding machine, use shielded
cables, use line filters, or shield the work area in one way or
another.
2.3.- Reducing electromagnetic fields
To reduce magnetic fields (EMF) in the work area, the following
proceedings should be used:
1. Keep cables as close together as possible, by braiding them,
or joining them with sticky adhesive tape, or using a cable cover.
2. Place cables at one side and away from the operator.
3. Do not wrap or hang cables about your body.
4. Keep welding power sources and cables as far away as
practical.
5. Connect grounding clamp to the piece you are working at, as
near as possible to the weld.
6. Make sure the ground is connected.
Warning: In environments with increased risk of electric
shock and fire, such as in the proximity of inflammable
products, explosives, height, restricted free moving
space, physical contact with conductive parts, warm and humid
environments that reduce the electrical resistance of human skin
and apparatus, observe the risk prevention in the workplace and
the national and international provisions as pertinent.
