Introduction

Thank you for purchasing one of our
products. Before using the equipment
9
you should carefully read the instruc-
tions included in this manual. In order to
get the best performance from the
system and ensure that its parts last as
long as possible, you must strictly follow
9
the usage instructions and the mainte-
nance regulations included in this
10
manual. In the interest of customers,
you are recommended to have mainte-
nance and, where necessary, repairs
10
carried out by the workshops of our ser-
vice organisation, since they have suita-
10
ble equipment and specially trained per-
sonnel available. All our machinery and
systems are subject to continual deve-
11
lopment. We must therefore reserve the
right to modify their construction and
11
properties.

Built according to the very latest IGBT
75
based inverter technology, these DC
power sources thanks to their excellent
76
arc characteristics, are recommended
for highest standard applications with
any electrode. Suitable to be used in shi-
77
pyards, steel construction, pipe welding
and maintenance, MATRIX 250 E
77
ensure an extraordinary stability of the
welding parameters and their "fast dyna-
mic characteristic" enables to achieve

MATRIX 250 E also allows the possibi-
lity of TIG welding with "lift" mode arc
striking.
FEATURES
• Excellent welding characteristics with
• Reduced weight and size, easy-to-
• Adjustable"arc force";
• Innovative and compact design;
• Metallic main structure with shock-
• Control panel protected against acci-
• Robust handle integrated into the
• Sloping front panel, easy to read and
• IP 23 protection class and dust-proof
• Automatic "hot start" to improve the
• Electrode Antisticking function;
• TIG welding with thermal controlled
• The generator also conforms to all

any type of electrode, including cellu-
losic;
carry;
proof plastic front panel;
dental impact;
chassis;
adjust and highly visible from any
direction;
electronic components, thanks to the
innovative "Tunnel" fan cooling
system, allow operation in the tou-
ghest work environments;
arc striking with the most difficult
electrodes;
(TCS) "lift" type striking reducing tun-
gsten inclusions to a minimum and
allowing to also strike on sharp edges;
