STAYER WELDING PLASMA 40 COM GE Manual De Instrucciones página 24

►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.

►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 interference.
• 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 soon correct any problem caused by the installation.
• 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 make sure that it 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 move 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 on, as
near as possible to the weld.
