2.3 Notes and requirements
The unit has been developed and constructed in accordance with recognised
technical knowledge.
However, using the unit may hold dangers for the life and limb of the user or third
parties or influence the unit or cause damage to other property.
None of the safety measures may be removed or put out of action, as this causes
risks and correct use of the unit cannot be guaranteed. Removing the safety
features during set up, repairs and maintenance is described specially. As soon
as this work is completed, the safety features must be replaced.
When using additional products (for example, solution for cleaning) the operator
of the unit is to ensure that the unit is safe for the product to be used.
All safety and danger notes as well as the type panel on the unit are to be
maintained, kept in a readable state and observed.
Safety notes serve to protect when working and to prevent accidents . They
must be observed.
The safety notes listed in this chapter must be observed along with the special
notes made in running text.
In addition to the instructions in these operating instructions, general safety and
accident prevention regulations (in Germany including UVV BGV A3, TRBS 2131
and BGR 500 Chapter 2.26 (formerly VGB15): "Welding, cutting and associated
processes" and in particular the references to arc welding and cutting and the
appropriate national regulations) must be observed.
Please also note the safety notices in the workplace of the operator.
REHM welding units are, unless explicitly permitted in writing by REHM; only for
sale to commercial and industrial users and only for use by such.
The INVERTIG.PRO inert gas welding units are designed in accordance with EN
60974-1 Arc welding equipment - Welding power sources for overvoltage
category III and pollution level 3 and with EN 60974-10 Arc welding equipment -
Electromagnetic compatibility for Group 2 Class A, and are suitable for use in all
areas, except residential, which are directly connected to a public low voltage
power supply. Due to the cable-related and radiated interferences it may be
difficult to guarantee the electromagnetic compatibility in these areas. For this
purpose, the observation of suitable measures to fulfil the requirements (filter for
network connection, shielding using, for example, screened lines, shortest
possible welding lines, grounding the work piece, equipotential bonding) as well
as the evaluation of the environment (for example, computers, control units, radio
and television masts, neighbouring persons, for example, those using a
pacemaker) should all be carried out. The responsibility for interferences lies with
the operator. See DIN EN60974-10:2008-09, Appendix A for more notes and
recommendations.
High performance units may affect the main power supply thanks to their high
power consumption. For certain units types, there may be connection restrictions,
requirements regarding the maximum permitted net impedance or requirements
regarding the minimum required available power at the point of connection to the
main power supply (see technical data) In these cases, the user of such a unit
must ensure, if necessary by consulting the power suppliers, whether the unit
may be connected.
INVERTIG.PRO TIG gas-shielded welding units should only be used

for the specified uses

in a safety-related correct condition
