Introduction; Properties; About Welding - Kemppi MinarcMig 180 Operation Instructions Manual

1. intrODuctiOn

MinarcMig™ Adaptive 180 is an easy-to-use MIG welding machine suitable for
both hobby and professional use. Before using or doing any maintenance work
on the machine, 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. The machine is suitable for a range of different
purposes and the possibility to use a long extention cord eases operation in
various sites. It is also suitable for generator use on construction sites.
The machine has both an automatic and manul mode. In the automatic mode,
you must first select the filler wire material after which the welding voltage and
wire feed speed can be adjusted with one control according to the thickness
of the welded sheet. Thus, selecting the right parameters is easy. In automatic
mode, the length of the arc, or welding heat, is trimmed with another control. In
manual mode, the welding voltage and wire feed speed are adjusted separately
with their own controls. The use of the machine is aided with a display which
also displays the welding current, welding voltage and wire feed speed.
You can also use steel wire (solid or cored wire), stainless steel wire or
aluminium wire as filler wire in the machine. The steel wire can be 0.6 mm,
0.8 mm or 1.0 mm thick, but the machine's welding properties are optimum
with a steel wire of 0.8 mm diameter. The stainless steel wire can be 0.8 mm,
0.9 mm or 1.0 mm in diameter and the aluminium wire 1.0 mm.

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. Earthing cable attached to
the workpiece guides the current back to the machine, forming the needed
closed circuit. Unrestricted current flow is possible when the earthing clamp
is properly attached to the workpiece and the fixing point of the clamp on the
workpiece is clean, paintless and rustfree.
Shielding gas must be used during welding in order to prevent air from mixing
with the weld pool. Pure carbon dioxide or a mixture of argon and carbon
dioxide is suitable for steel wire shielding gas. Argon + 2 % CO ² mixture is
