Thank you for having purchased our product. Please read
instructions on use in this manual
as well as the safety
rules given in the attached booklet
and follow them care-
fully to get the best performance from the plant and be sure
that the parts have the longest service life possible. This
manual will show you the best way to do any maintenance
jobs or repairs eventually needed by your plant to resolve
any eventual problems, we do however recommend our
customers to arrange to have maintenance and eventual
repairs done at our servicing centers as they have the right
equipment and the highly qualified personnel is constantly
updated. All our machinery and systems are subject to con-
tinual development. We must therefore reserve the right to
modify their construction and properties.
The synergic multifunction
NBM-500L
power source, based
on the most modern IGBT based inverter technology with
digital control, allows high quality welding both in MIG/MAG,
and in Pulsed MIG on all materials and particularly on
stainless steel, aluminum and galvanized steel, by minimiz-
ing any reworking job after welding thanks to its spatter free
performance.
Technologically advanced, robust and easy-to-use,
NBM-500L
represents the ideal solution for any application
requiring high precision and repeatability of the achieved
results, by making this power source particularly suitable for
the most qualified jobs in any industrial application. The high
versatility of
NBM-500L
also achieves performances in
MMA welding.
The wire-feeder was designed for using all types of wire,
either solid or cored, and must only be used as part of the
welding generator and not for improper or any other use.
The general technical data of the system are summarized in
NBM-500L
The main feature of the welding unit
NBM-500L
are:
• Innovative and user friendly design;
• Metallic main structure with shockproof plastic front
frames;
• Robust handles built into the chassis;
• Control panel protected against accidental impact;
• Synergic digital control of all the welding parameters;
• BURN BACK control. At the end of each weld, in any con-
dition and with any material, the digital control ensures a
perfect wire cut, prevents the typical “wire globule” from
forming and ensures correct arc restriking;
• Spatter free exceptional welding characteristics in both
MIG/ MAG, MIG Pulsed and MIG Dual Pulsed on any
material and with any gas;
• High welding performance in MMA mode striking;

Wave form control. Both welding parameters and pulse
wave form, digitally controlled by the microprocessor, are
monitored and modified every few microseconds in order
to keep the arc constantly precise and stable by com-
pensating for continuous changes in welding conditions
caused by torch movement and workpiece irregularity;
• Ability to store personalized welding programs;
• Monitoring and repetition of welding parameters;
• User friendly and easy-to-use selection and recalling of
