The

«ET- hydroge

n L/350 Welder

is a

machine marked

with « CE» symbol in compliance

with European

Union

regulation

pursuant to

EEC Directive

2014/35/UE and 2014/30/CE

detailed in the UE

Declaration

Conformity annexed to

each

machine.

DESCRIPTION

The «ET Hydrogen Welder L/350» can be used in craftwork or industrial workshop with a

minimum volume of 30 m³ and provided with natural ventilation by means of suitable openings to

the outside in compliance with the regulations in force in the user’s country. This machine is mainly

used for soft and hard brazing applications in the fields of jewellery, goldsmith, costume jewellery,

dental mechanics, micromechanics, and for welding materials such as platinum, beryl, nickel,

thermocouples, enamel copper, glass, quartz and for welding metal to metal and applicable for

welding in industry, within the limitations of the machine.

USE LIMITATIONS

The hydrogen and oxygen mixture produced by this welder must be solely used to produce one

flame for braze welding or thermal treatments of metal parts in general, or for working quartz glass.

DANGER

Any use different from those quoted here within and not included or not directly inferred

from this instructions’ manual, will be regarded as «NOT ALLOWED».

It is not permitted to operate the machine when the flame is out. This would result in an

accumulation of explosive mixture in the surrounding environment and pollution caused by

the methyl alcohol.

The machine has been designed for professional use. The operator must be of proven

ability and capable of reading and understanding the instructions given in this manual.

The operator must also use the machine in accordance with the ruling accident prevention

standards, operating conditions and characteristics of the machine.

DANGER

THE USE OF THE MACHINE FOR ANY OTHER PURPOSE THAN THAT DESCRIBED IN THIS

MANUAL RELIEVES THE MANUFACTURER OF ANY RESPOSIBILITY FOR DAMAGES TO

PERSONS, ANIMALS OR THINGS RESULTING FROM INAPPROPRIATE USE.

1.6 NOISE

The noise level (acoustic pressure) was determined with the machine running under no load

conditions with the readings of the 70 dB(A) inferior.
