CHAPTER 6. SAFETY MEASURES.
The use of this equipment requires a maximum amount of responsibility with respect to their use and
maintenance. Read this safety chapter carefully as well as the rest of the instructions manual. The correct use
of the equipment will depend on this.
For your safety and that of others, remember that:
ANY PRECAUTION MAY BE INSUFFICIENT!
The welding equipment referred to in this manual are electrical. It is
important therefore to observe the following safety measures.
•
Any work on the equipment must only be carried out by specialists.
•
The equipment must be connected to the earth connection and this must always
be effective.
•
The equipment must not be located in a damp place.
•
Do not use the equipment if the welding or supply cables are damaged. Use
original spares.
•
Make sure that the part to be welded makes perfect electrical contact with the equipment earth.
•
During any maintenance operations or when dismantling any element from the inside of the machine, this
must be disconnected from the electricity supply.
•
Do not touch the equipment switches when carrying out a welding operation.
•
Never lean directly on the work part. We will always work with protection gloves.
•
Any work on the welding guns and earth clamps will be done with the equipment disconnected (OFF
Position (O) on the on/off switch). Do not touch the electrically active parts (electrode-holder clamp, earth
clamp, etc.) with your bare hand.
The part to be worked on should be cleaned from possible grease or
solvents as these may decompose during the welding process giving off fumes which
could be very toxic. This can also occur with those materials which have some kind
of surface coating (zinc-plated, galvanised, etc.). Avoid inhaling the fumes given off
in the process at all times. Protect yourself from the fumes and metal dust which can
be given off. Use quality approved anti-fume goggles. Work with this equipment
must be carried out in places or working posts where there is suitable air renewal. If
welding processes are carried out in closed places the use of suitable fume
extractors is recommended.
In welding processes, the electric arc formed gives off infrared and
ultraviolet type irradiations, these are harmful for the eyes and skin, so these areas
must be suitably protected with gloves and suitable clothing. The eyes must be
protected with goggles with an quality approved protection system with a protection
index of at least 11. With electric arc welding machines use protection shield for the
eyes and face. With electric cutting machine use protection goggles. Always use
quality approved protection elements. Never use contact lenses. They may adhere to
the cornea due to the great heat given off during the process. Bear in mind that the
arc is considered to be dangerous within a 15-metre radius.
Cast material projections are given off during the welding process so due
precautions must be taken. There must be a fire-extinguisher near to the working
area. Do not keep inflammable material or explosives near to the working post.
Prevent fire caused by sparks or slag. Use quality approved footwear for this type of
operations. Use approved acoustic protectors in case of too high noise.
Never direct the path of the MIG welding gun towards people. The danger
exists of activating the system.
In environments with a high risk of electrical shock, fire, proximity of
inflammable products or height, observe relative national and international
provisions.
