Safety Instructions - WIDMANN MIG/TIG/MMA-160 Manuel Utilisateur

1. INTRODUCTION
This is an easy-to-use MIG/TIG/MMA 3 in 1 welding machine suitable for both
hobby and professional use. Before using or doing any maintenance work on the
machine, please read the operating manual and keep it for further reference.
1.1 PROPERTIES
The welding machine is small, efficient and extremely light. It is easy to carry with
the help of a shoulder strap (optional). The machine is suitable for a range of different
purposes and the possibility to use a long extension cord eases operation in various
sites. It is also suitable for generator use on construction sites.
Welding voltage and wire feeding speed are adjusted with knobs control according to
the thickness of the welded sheet. Thus, selecting the right parameters is easy.
The machine's welding properties are optimum with a steel wire of 0.8 mm diameter.
Also, 0.6 mm. 0.9 mm or l.0 mm solid wire or flux cored wire can be used as filler
wire.
1.2 ABOUT WELDING
In addition to the welding machine, welding outcome is influenced by the piece being
welded and the welding environment. Therefore, recommendations in this manual
must be followed.
During welding electric current is led with the welding gun's current nozzle to the
filler wire and via that to the welded piece. Earth cable attached to the workpiece
guides the current back to the machine, forming the needed closed circuit, unrestricted
current flow is possible when the earth clamp is properly attached to the workpiece
and the fixing point of the clamp on the work piece is clean, paint less and rust-free.
Shielding gas must be used under gas mode during welding in order to prevent air
from mixing with the weld pool. Carbon dioxide or a mixture of carbon dioxide and
argon is suitable for shielding gas. Some filler wires form a shielding gas from the
wire's filling as it melts thus eliminating the need for a separate shielding gas.

2. SAFETY INSTRUCTIONS

The machine is safe to use due to its plastic cover, which does not conduct electricity.
The welding gun has an overheating protector which prevents operation when the
machine is overheated. The machine is also protected from too low or too high supply
voltage.
However, there are some risk factors connected to welding. You should therefore read
and follow the following safety instructions carefully.
2.1 USE OF PROTECTIVE ACCESSORIES
The arc and its reflecting radiation damage unprotected eyes. Always protect your
eyes and face with an appropriate welding mask. The arc and welding spatters burn
