USER'S MANUAL
Read the following manual of instructions carefully before
using the welding machine.
The MMA coated electrode arc welding systems referred herein as
"welding machines" are meant to be used only for industrial and
professional use.
Make sure the welding machine is installed and repaired only by
a qualified person or experts, in compliance with the law and the
accident prevention regulations.
Make sure the operator is appropriately trained in the use and risks
related to the arc-welding processes, and in the required measures
of protection and emergency procedures.
More detailed information can be found in the "Installation and use or
arc-welding equipment" brochure EN 6094-9.
SAFETY WARNING
- Make sure the power socket the welding machine is
connected to, is protected by suitable safety devices (fuses or
an automatic switch) and grounded.
- Make sure the plug and power cable are both in good condition.
- Before plugging into the power socket, make sure the welding
machine is switched off.
- Switch the welding machine off and pull the plug out of the power
socket before connecting the welding cables, replacing any parts
in the torch or wire feeder, carrying out maintenance operations, or
moving it (always use the carrying handle of the welding machine).
- Do not touch any live part with bare skin or while wearing wet
clothing. Appropriately insulate yourself from the electrode, the piece
to be welded and any grounded accessible metal components. Make
sure you use gloves, footwear and clothing especially designed for
this purpose, and dry, non-flammable insulating mats.
- Use the welding machine in a dry and well-ventilated space. Do not
expose the welding machine to rain or direct sunshine.
- Use the welding machine only if all panels and guards are mounted
and placed correctly.
- Do not use the welding machine if it has been dropped or struck, as
it may not be safe.
Make sure it is periodically checked by a qualified person or an expert.
- Eliminate any welding fumes through appropriate natural
ventilation or by using a smoke exhauster. A systematic
approach must be used to asses the limits of exposure
to welding fumes, depending on their composition,
concentration and the length of exposure.
- Do not weld materials that have been cleaned with chloride solvents
or that have been near such substances.
- Use a welding mask with adiactinic glass suited for welding. Replace
the mask if damaged; it may let the radiation in.
- Wear fireproof loves, footwear and clothing to protect the skin from
the radiation produced by the welding arc and from sparks. Do not
wear greasy garments because a spark could set a fire. Use protective
screens to protect people nearby.
- Hot metal parts, electrode holder grippers, electrode stubs and
freshly welded pieces must not come into contact with bare skin.
- Metal-working produces sparks and splinters. The user must wear
safety goggles with protective side-eye guards.
- Welding sparks can set a fire.
- Do not weld nor cut anywhere near inflammable materials, gasses
or vapors.
- Do not weld nor cut containers, cylinders, tanks or piping, unless a
qualified technician or expert has previously checked if it is possible to
do so, or they have already made the appropriate preparations before
the weld.
- Remove the electrode from the electrode holder gripper when you
have completed the welding operations. Make sure that no part of the
electrode holder gripper electric circuit touches the ground or earth
circuits. An accidental contact could cause overheating or fires
EMF Electromagnetic Fields.
Welding current creates electromagnetic fields (EMF) near the
welding circuits and the welder. Electromagnetic fields may interfere
with medical prostheses such as pacemakers.
Suitable and enough measures should be implemented in order to
protect those operators that suffer from those medical issues. For
instance, they should not be allowed to enter the area where a
welding equipment is being used. Any operator with health issues
should consult their doctor before getting close to those welding
areas.
This device meets the specific requirements for the technical
standards of the product and is intended for a professional use
only in an industrial environment. It is not safe to weld at home,
as electromagnetic fields will probably affect those exposed to the
process.
Follow these strategies to minimize the exposure to electromagnetic
fields (EMF):
- Do not place your body between the welding cables. Both welding
cables must be on the same side and apart from your body.
- Twist both welding cables together and secure them with tape
when possible.
- Do not wrap the welding cables around your body.
- Connect the earth cable to the workpiece as close as possible to
the area to be welded.
- Keep your head and body as far as possible from the welding
circuit. Do not work close to the welder, nor seated or leaning on it.
Keep a minimum distance: Fig 5 Da = cm 50; Db = cm 20.
Class A equipment
This equipment has been designed to be used only in professional
and industrial environments.
If this equipment is used in domestic environments, and those are
directly connected to a low voltage power supply network, which
supplies buildings for domestic purposes, it may be difficult to
ensure an appropriate electromagnetic compatibility as the result of
conducted or radiated disturbances.
Welding in conditions of risk
- If welding needs to be done in conditions of risk (electric discharges,
suffocation, in presence of inflammable or explosive materials),
make sure an authorized expert previously evaluates the conditions.
Make sure an expert or a trained person so they may intervene
in case of emergency. Use the protective equipment described in
normative of EN 60974-9.
- If you are required to work higher than the ground level, always use
a safety platform.
- If more than one welding machine need to be working on the
same piece, or maybe electrically connected pieces, the sum of the
no-load voltages on the electrode holders or on the torches, may
exceed the safety levels.
Make sure an authorized expert previously evaluates the working
conditions to see if that risk may appear in order to adopt the
appropriate
protective
regulations.
Additional warnings.
- Do not use the welding machines for purposes other than those
that do not belong to its function, for example, to thaw frozen water
pipes.
- Place the welding machine on a flat and suitable surface, and make
sure it can not move.
It must be positioned in such a way as to allow it to be controlled
during its use, but without the risk of being covered with welding
sparks.
- Do not work with the welding machine hung from its body, use the
straps or any other suitable device for that purpose.
- Do not lift the welding machine. There are no lifting devices in the
equipment.
- Do not use cables with damaged insulation or loose connection.
