ELETTROLASER S.R.L.CONTRACTUAL GUARANTEE
The producer guarantees the defects absence, taking into consideration of the actual technological
phase, about the new equipment type and for the duration of two years from the installation date
c/o the customer included in the transportation documents. It being understood the limit of two
years, the guarantee obligation spreads also to those equipment parts not produced directly by
Elettrolaser S.r.l. with the exclusion of LED lamps for the welding room illumination, fuses,
protection glass, fire lens and all consumable material. The producer lends guarantee proceeding
at his discretion, in accordance with the technical requirements, to the repair or to the change if
faulty pieces. In the case the producer admits a guarantee right the relative intervention costs are
at his charge. The pieces that present material or working defects and those ones consequently
damaged are changed. The changed pieces become of Elettrolaser S.r.l. property. For the
changed after an intervention in guarantee, this is admitted up to the equipment guarantee
maturity.
The guarantee right doesn’t exist when the happened defect is in relation with the following cases:
The buyer hasn’t denounced the defects to the producer within eight days from the
installation date, in writing o giving job for the execution of the relative intervention.
The device or its parts have been used in different ways for the use to which have been
assigned
The device has been entrusted for the repair to an extraneous subject to Elettrolaser S.r.l. or
the device or its pieces have had some modifications not authorized by Elettrolaser S.r.l.
The prescriptions about the use and the maintenance of the machine included in this manual
have not been respected
The guarantee seals on the machine closure panels have been removed.
Besides the defects and the damages are excluded from the guarantee deriving from the normal
wear or from natural events. It being understood on behalf of the buyer the performance right in
guarantee in the terms above showed, it is excluded expressly that the buyer can request the
contract solving, the machine change or the sale price reduction and the compensation of possible
direct and indirect damages.
Possible omissions and/or negligence of the user, if provoke our technician intervention, allow the
relative expenses debit on behalf of Elettrolaser S.r.l.

CHAPTER 1 SYMBOLS
Generic warning:
This symbol shows the necessity of a careful reading of the manual or the necessity
of an important manoeuvre or maintenance operation.
Laser warning:
This symbol shows the exposition danger to the laser visible and invisible radiation.
This symbol can be included also on the machine in correspondence of risk zones.
In presence of this symbol so:
•Don’t introduce ever mirrors or reflecting objects in the welding room while
the machine is in function.
•Check the products exclusively from the peephole placed on the front nose.
•Don’t remove ever the curtains for the hands insertion.
During the machine use move the childs and the people of small height.
It is advised to the user to protect the hands with adequate and approved working
gloves.
Fire warning:
This symbol shows the fire danger when inflammable materials are processed. This
symbol shows the fire danger when the inflammable materials are processed. When
there is fire danger, it is indispensable to follow the indications provided from the
manufacturer during the put in service of the machine.
Don’t weld where the sparks can meet inflammable material.
Remove all the inflammable materials near to the LASER welder. If this isn’t possible
cover them carefully with fireproof material.
Fire attention: keep extinguishers in the vicinity.
Explosion warning:
This symbol shows that the gas contained in the cylinders is under pressure and can
consequently explode if the cylinders aren’t treated with the necessary cautions.
Protect the cylinder from excessive heat and mechanical stresses.
Install the cylinders in vertical position and block them with a fixed support chain or
with a proper cylinders case to avoid falls or knocks.
Maintain the cylinders far away from the welding place and from any electric circuit.
Use only regulation cylinders, pressure reducers, pipes and joints approved for the
specific use; maintain them in good conditions together with the connected parts.
Don’t expose the face towards the valve exit placed on the cylinder when this one is
opened.
Maintain the valve always covered with a correct screw hood except when the
cylinder gas is used or when the cylinder is connected to the machine.
Gas and fumes warning.
The welding processes produce fumes and gas, breath them can be dangerous for
the health.
Keep the head a long way from fumes, don’t breathe the fumes.
Don’t cover the grids placed on the machine.
Read with attention the supplied instructions about the different types of metals,

Elettrolaser S.r.l. - 10 - MEGAHIT
cleaning substances and protection gas.
Prefer a wide room dedicated appropriately for the machine installation. If the room
is of reduced sizes use it only if well ventilated. The protection gas used to weld can
gradually change the air causing indisposition or death. Assure that the air that is
breathed is healthy.
Don’t weld near the degreasing, cleaning or vaporization areas. The heat could react
with the vapors forming very toxic and irritating gases.
Check that the metals haven’t impurities to provoke fumes or gases during the
melting.
Electric warning:
This symbol shows dangerous voltages associated to the laser, or however of
sufficient width to induce electric risk. This symbol can be showed also on the same
machine in correspondence of risk zones.
Touch electric parts under voltage can provoke fatal damages or serious burns. The
electric circuits are always under voltage when the machine is switched on. The not
correct installation or the machine inappropriate grounding represents a danger.
Don’t touch electric parts under voltage.
Remove the feeding plug from the net before to install or make maintenance to the
machine.
Install correctly and connect to ground this machine following the use Manual and
respecting the standards and local rules.
Switch off the machine after the use.
Don’t use the weak cables, damaged, of insufficient section or mal connected.
Pay attention to have not cables near to heat sources.
Use only equipment in perfect conditions. Repair or change immediately the
damaged parts.
Maintain all covering panels fastened and in their seats.
Important warning:
This symbol shows the necessity of a careful reading of the manual on behalf of the
operator.
