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.
