1. INTRODUCTION
MinarcMig™ Adaptive 150 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.
Welding voltage and wire feed speed are adjusted with one control according to
the thickness of the welded sheet. Thus, selecting the right parameters is easy.
The length of the arc, or welding heat, is trimmed with another control, and
once the right value is found there usually is no need to change it even when
welding a thicker or thinner sheet.
The machine’s welding properties are optimum with a steel wire of
0.8 mm diameter. Also, 0.6 mm, 0.9 mm or 1.0 mm solid wire or cored wire
can be used as filler wire. Note, however, that the machine is designed for steel
wire welding only.
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. 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.
