Description
Powerful, compact, and light-weight - thanks to the innova-
tive digital welding control the MATRIX 420-4200 units are the
highest performance and most technically advanced electrode
welding generators you can find.
Built according to the very latest IGBT based inverter tech-
nology, these DC power sources thanks to their excellent arc
characteristics, are recommended for highest standard appli-
cations with any electrode.
MATRIX 420-4200 units guarantee absolute stability of welding
parameters and thanks to their “characteristic dynamic speed”
they are ideal for quality welding particularly difficult jobs using
basic and cellulosic electrodes. The MATRIX 420-4200 units
can also be used for TIG welding with a “Lift” type ignition.
FEATURES
• Innovative and compact design.
• Reduced weight and size, easy-to-carry.
• Metallic main structure with shock-proof plastic front panel.
• Controls protected against accidental blows.
• Robust handle integrated into the chassis.
• Slanting front panel with wide range of visibility from all an-
gles to facilitate reading and adjusting parameters.
• Digital ammeters and voltmeters are standard fittings, with
pre-setting of welding current and saving of the latest value
(Hold function).
• Digital control of all welding parameters.
• Possibility of saving the welding parameters (99 automatic
welding points - JOBS).
• Self-diagnosis device.
• Exceptional welding characteristics for all types of electrode,
including cellulosic.
• MMA welding:
- “Arc Force” adjustable to select the best dynamic charac-
teristics for the welding arc.
- “Hot Start” adjustable to improve ignition with particularly
difficult electrodes.
- Anti-sticking function to avoid the electrodes sticking.
• TIG welding:
- TIG welding using the innovative “Lift” type thermally con-
trolled ignition (TCS). Ignition comes about precisely and
quickly, reducing the inclusions of tungsten to a minimum
and doing away with incisions into the workpiece to be
welded.
- A synergic SWS (Smart welding stop) system that reduces
electrode consumption and avoids oxidation of the weld-
ed joint.
• Overheating thermostatic protection.
• Automatic compensation for mains voltage fluctuations with-
in +15% -20%.
• Safety barrier against excess voltage from mains.
• The VRD (Voltage Reduction Device) can be activated, which
reduces voltages to below 12 V, which means that the weld8
ing machine can be used in ambient conditions in which there
is a high electrical risk, thereby providing maximum opera-
tor safety.
• An “Energy Saving” function that only activates ventilation
of the generator when necessary, making significant energy
saving possible and reducing maintenance, due to the small
quantity of dust and pollutants that are taken in.
• IP 23 S protection class and dust-proof electronic compo-
nents, thanks to the innovative “Tunnel” fan cooling system,
allow operation in the toughest work environments.
• Can be connected to motor-powered generators of adequate
capacity providing high dependability - 30 kVA (MATRIX 420-
4200 E-MG).
• Useable with power supply cables more than 100 m long.
• Reduced energy consumption.
Introduction
Thank you for buying our product.
