2.5 Residual risks
TECNA s.p.a. disclaims any responsibility for damage
to persons, property or the machine itself caused
by improper use, insufficient and/or superficial
observance of the safety guidelines given in this
manual, tampering, however slight, or the use of non-
original or incompatible spare parts.
The information provided in this manual refers to the
use of the product as intended by the manufacturer;
for cases of use not conforming to those covered by
this manual, the user is responsible for conducting a
risk analysis.
2.5.1 Ergonomic hazard
During use of the machine, the operator may be
exposed to ergonomic risks, such as
overloading or awkward positions.
We recommend conducting an ergonomic risk
assessment based on the actual working tasks
performed by the user of the machine.
2.5.2 Crushing hazard
When using the machine, the operator is exposed to
a hand-crushing hazard due to the movement of the
electrodes and arms.
Start the welding holding the pneumatic gun by the
two provided handles.
To keep the welding surfaces together, use a tool that
ensures the operator's safety (e.g. a self-locking clamp).
2.5.3 Dangers from magnetic fields
During use of the machine, the operator is exposed to
an electromagnetic field due to the continuous flow of
high currents.
DANGER
THE machine must not be used by
persons with biomedical implants (e.g.
pacemakers, metal prostheses, etc.)
without first consulting their doctor.
CAUTION
The magnetic fields generated by the
machine can cause strong attraction
in magnetic metals and can damage
magnetically sensitive equipment.
NOTE
The pneumatic gun is equipped with an
incorporated welding transformer and
thus the emission of electromagnetic
fields is minimal.

2.5.4 Fume inhalation hazard
Analyse the work conditions and use suitable extraction
equipment if the welding operations generate fumes.
2.5.5 Burn hazard
The cables and electrodes on the machine can reach
very high temperatures during prolonged use.
DANGER
Remove the electrodes using the special
tool provided, taking care to avoid any
contact with hot parts.
DANGER
Do not remove the arm until it has cooled
down.
The high electrical current used by the machine can
cause metal objects located in its vicinity to overheat.
WARNING
When using the machine, do not wear
rings, watches or clothing with metal
parts or accessories.
2.5.6 Danger of overheating
The ventilation grilles on the machine must not be
covered.
Insufficient ventilation can cause the machine to
overheat.
2.5.7 Fire hazard
The surfaces on which the work is performed can reach
very high temperatures.
WARNING
Ensure that there are no flammable
materials in contact with or close to the
surfaces on which to work is to be done.
The electrodes on the machine can reach very high
temperatures during prolonged use.
WARNING
Store the electrodes in a suitable place
where they can cool down in total safety
(for example, on the ground).
Keep the surrounding area free from
flammable materials.
