5.6. NOISE
The equivalent continuous A-weighted sound pres-
sure level, emitted by the machine at the workplace
in full operating conditions, is less than 70 dB (A).
These emissions comply with the limits of the regula-
tions in force and are not such as to generate danger
for operators.
Arc welding processes can, however, produce noise
levels above this limit. Therefore, users must imple-
ment the precautions required by law.
