Introduction
Thank you for purchasing one of our
products. Before using the equipment
you should carefully read the instruc-
tions included in this manual. In order to
get the best performance from the sys-
tem and ensure that its parts last as long
as possible, you must strictly follow the
usage instructions and the maintenance
regulations included in this manual. In
the interest of customers, you are rec-
ommended to have maintenance and,
where necessary, repairs carried out by
the workshops of our service organisa-
tion, since they have suitable equipment
and specially trained personnel availa-
ble. All our machinery and systems are
subject to continual development. We
must therefore reserve the right to mod-
ify their construction and properties.
Description
MATRIX 250 HF
high-frequency striking
TIG
generator - which is the result of the
ultimate
IGBT
- based inverter technol-
ogy - is equipped with a complete and
new digital control on all welding param-
eters.
MATRIX 250 HF
is a technologically ulti-
mate, strong and easy-to-use generator;
when used in direct current, it allows
TIG
welding of stainless steel, carbon steel,
copper and its alloys, also ensuring ideal
performance in
MMA
weld, with any
type of electrode.
FEATURES
• Digital control of all the welding
parameters.
• Standard equipped with pulse mode
integrated into the control with availa-
ble "EASY PULSE" facility.
• Excellent TIG welding characteristics.
• High frequency Arc Striking, precise
and efficient even from long distance.
• "Energy Saving" function to operate
the power source cooling fan and the
torch water cooling only when neces-
sary.
• Automatic compensation for mains
voltage fluctuations within +15% -
20%.
• Very good MMA welding characteris-
tics with any type of electrodes.
• Easy-to-use.
• Low energy consumption.
• Ability of storing and recalling person-
alised welding program.
• Electromagnetic disturbance reduc-
tion because of high frequency used
at arc striking only.
• Using special TIG torches allows
remote adjustment of welding current
directly from the torch.
• Overheating thermostatic protection.
• Compact and innovative design.
• Metallic main structure with shock-
proof plastic front panel.
• Control panel protected against acci-
dental impact.
• Robust handle integrated into the
chassis.
• Sloping front panel easy to read and
adjust and highly visible from any
direction.
• Reduced weight and size, easy-to-
carry.
• IP 23 protection class and dust proof
electronic components, thanks to the
