16 Introduction
16 Thank you for purchasing one of our products. Please read
instructions on use in this manual as well as the safety rules
given in the attached booklet and follow them carefully to get
17
the best performance from the plant and be sure that the parts
have the longest service life possible. In the interest of custom-
17
ers, you are recommended to have maintenance and, where
necessary, repairs carried out by the workshops of our service
17
organisation, since they have suitable equipment and specially
trained personnel available. All our machinery and systems are
subject to continual development. We must therefore reserve
17
the right to modify their construction and properties.

MATRIX 250 AC/DC high-frequency striking TIG generator -
18
which is the result of the ultimate IGBT- based inverter tech-
nology - is equipped with a complete and new digital control
18
on all welding parameters.
MATRIX 250 AC/DC is a technologically ultimate, strong and
20 easy-to-use generator; when used in direct current, it allows
TIG welding of stainless steel, carbon steel, copper and its
alloys, aluminium and its alloys, also ensuring ideal perform-
26
ance in MMA weld, with any type of electrode.
FEATURES
26
• Digital control of all the welding parameters.
• Standard equipped with pulse mode integrated into the con-
26
trol with available "EASY PULSE" facility.
• Slow pulsation under 10Hz gives the possibility to set peak
time and base time in independent way.
27
• Excellent TIG welding characteristics.
• High frequency Arc Striking, precise and efficient even from
long distance.
27
• "Energy Saving" function to operate the power source cool-
ing fan and the torch water cooling only when necessary.
28
• Automatic compensation for mains voltage fluctuations
within +15% -20%.
28
• Very good MMA welding characteristics with any type of
electrodes.
• Easy-to-use.
171
• Low energy consumption.
• Ability of storing and recalling personalised welding pro-
172
gram.
• Electromagnetic disturbance reduction because of high fre-
174
quency used at arc striking only.
• Using special TIG torches allows remote adjustment of weld-
174
ing current directly from the torch.
• Overheating thermostatic protection.
• Compact and innovative design.
177
• Metallic main structure with shock- proof plastic front panel.
• Control panel protected against accidental impact.
179
• Robust handle integrated into the chassis.
• Sloping front panel easy to read and adjust and highly visible
180-186
from any direction.
• Reduced weight and size, easy-to-carry.
• IP 23 protection class and dust proof electronic compo-
186
nents, thanks to the innovative "tunnel" fan cooling system,
allow their use in the toughest environments.
