Introduction
Thank you for purchasing a Masterweld product, you
have invested in a quality product manufactured in
Europe.
Before using the equipment you should carefully
read the instructions 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 recommended
to have maintenance and, where necessary, repairs
carried out by the workshops of our service organisa-
tion, since they have suitable equipment and special-
ly trained personnel available. All our machinery and
systems are subject to continual development. We
must therefore reserve the right to modify their
construction and properties.
Description
Machines 2040 and 2050 are a simple portable weld-
ing apparatus for the MIG/MAG welding method
suitable both for professional and DIY use. It is a
welding apparatus with ‘flat’ characteristics. This
concerns the welding in inert gas protective atmos-
phere, where the filler metal is supplied in a form of
‘endless’ wire into the welding bath by the wire feed
mechanism. This method is very productive and
particularly suitable for welding of structural and
low-alloy steel types.
Machine 2040 is available in two versions - with
fixed welding torch and earthing cable and with
euro connectors. Machine 2080 is available only
with euro connectors.
Lightweight and small, the welding apparatus fea-
tures in its high efficiency. A plastic handrail is used
for easy transport. The device can be suitably sup-
plied with power from a standby generator, e.g. on
building sites. Welding parameters can be easily
adjusted on the apparatus, welding voltage and wire
feed rate are adjustable by a single control element
at the same time according to the welded material
thickness. The control element is used for fine volt-
age corrections that determine the arc length (weld
temperature). If the correct value is set, it will not be
necessary to change it any more even if there is
a need to weld a material more or less thick. The
apparatus is optimally adjusted for welding of steel
