FOREWORD
Thank you for purchasing our products. When
assembled and used correctly, our welding
generators are reliable and long-lasting and
will help increase the productivity of your bu-
siness with minimum maintenance costs.
These generators of direct current (model
415HF-420HF/C), when completed with their
own accessories, may only be used for the
welding of coated electrodes (celluloid/alumi-
num, included for models 400C-420HF/C) or
for welding with tungsten infusible electrode
under the protection of inert gases. In the lat-
ter case, the power generators can be used
with air- or water-cooled torches, with their
relative cooling unit (specifi c unit composition
for generators Compact 415HF-420HF/C).
All these appliances were designed, manu-
factured and tested entirely in Italy, in full ac-
cordance with the European Directives of Low
Voltage (2006/95/EC) and EMC (2004/108/
EC), by applying norms EN 60974.1 (safe-
ty rules for electric material, Part 1: source
of welding current) and EN 60974-10 (EMC
Electromagnetic Compatibility) and are iden-
tifi ed as Class A products.
Class A appliances were not designed for use
in domestic environments in which power is
supplied through a public low-voltage grid; it
is therefore potentially diffi cult to ensure the
electromagnetic compatibility of Class A ap-
pliances in such environments, due to radia-
ted and conduced disturbances.
These professional electric appliances must
therefore only be used in industrial envi-
ronments, connected to private power distri-
bution cabins.
These generators are therefore not subject
to the European/International EN/IEC regula-
tion 61000-3-12 which defi nes the maximum
levels of harmonic distortion induced in the
public grid of low-voltage power distribution.
The installer or the user (if necessary, con-
tact your power distributor) is responsible for
ensuring that these appliances can be con-
nected to a public low-voltage grid.
Warning: the manufacturer refuses all re-
sponsibility in the event of unautho-
rized modifi cations performed on its
products. These power generators
must only be used for the welding
procedures described above; they must ne-
ver be employed to recharge batteries, for
the thawing of water pipes, for the heating of
buildings by means of added resistances etc.
Compliance to RoHS Directive: We hereby
declare that the range of 3PH generators
described in this manual is in accordance
with RoHS EU Regulations 2002/95/CE of
27 January 2003 regarding the restriction of
the use of certain substances harmful for hu-
man health present in Electric and Electronic
Equipment (EEE).
This symbol, applied to the welding generator
or to its packaging, indicates that, at
the end of its useful life, the product
must not be treated as ordinary wa-
ste, but must be collected separately
from other waste and in accordance
with European Directive 2002/96/CE of 27
January 2003 regarding the disposal of waste
electrical and electronic equipment (WEEE).
These must be collected separately and di-
sposed of in an environmentally compatible
way. As owner of an EEE product (Electrical
Electronic Equipment), you are responsible
for contacting your area dealers for informa-
tion on authorized collectors. Applying the
above mentioned European Directive impro-
ves the environment and our own health.
Warning: Welding, cutting and similar
techniques may be dangerous
operations for the worker and for
anyone near the working area.
Please carefully read the SAFETY
chapter below in order to reduce risks.
