TECHNOLOGY.
Our engineers know what they are doing when it comes to top class welding equipment.
They keep in close contact with those who know best what good welding equipment
is all about: the craftspeople. That is why a Metabo welding device has everything you
need. That is a promise, because in addition to designing our welding equipment from
start to finish, we also produce and assemble it - from the transformer to the entire
electronics. The strictest of quality checks are therefore quite normal and the five year
warranty on the main transformer is a logical conclusion. Metabo. Work. Don’t play.

Electrode welding, TIG welding, MIG/MAG welding –
Metabo has the right welding unit for all materials and
for every thickness. However, that is not enough: Our

Electrode welding.
The electric arc burns between the
workpiece and a melting electrode.
The electrode provides the
additional material.
The melting case forms gases
and slag to protect the electric arc
and melting bath from negative
atmospheric influences.
Can be used for almost all
weldable materials from approx.
1.5 mm on (adapt stick electrodes

TIG welding.
The electric arc burns between
the workpiece and a non-melting
tungsten electrode (TIG = Tungsten
Inert Gas).
A separately fed inert gas (e.g.
Argon (Ar)) protects the welding
zone from negative atmospheric
influences.
Additional material can be fed
manually if required.
The TIG DC (direct current) method
is for welding all metals from
0.3 mm on, except aluminium and
magnesium. (The TIG torch must
always be connected to the negative pole).
MIG/MAG welding.
The electric arc burns between the
workpiece and a mechanically fed
welding wire (electrode).
An automatically fed non-com-
bustible gas protects the electric
arc and the melting bath from
negative atmospheric influences.
The MIG method (MIG = Metal
Inert Gas) is for processing aluminium and aluminium alloys.
Argon (Ar), Helium (He) and their
mixtures are used as gases.
The MAG method (MAG = Metal
Active Gas) is used for processing
general construction, tank and
The TIG AC method (alternating
current) must be used for alu-
minium, magnesium and their
alloys (breaking of the oxide layer
on the material).
The advantage of the method is
the good control of the concentra-

TECHNOLOGY
An optimisation of the output factor
is achieved using the sinus-inverter
techno logy by Metabo. This means
that a higher output is possible with
t
lower current consumption from the
230 V energy supply.
Advantages:
High welding output at 230 V
(electrode up to 170 A).
No oversized current generators
due to the reduced power consumption.
Welding gaps that can be caused
by long cable extensions, are a
thing of the past.
Future standards are already
met today.
