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, efcient 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 rst select the ller 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 ller 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 inuenced 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 ller 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 ow is possible when the earthing clamp
is properly attached to the workpiece and the xing 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 % CO² mixture is

suitable for stainless steel wires. Argon is suitable for welding aluminium
wires. Some ller wires form a shielding gas from the wire’s lling 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 reecting radiation damage unprotected eyes. Always protect
your eyes and face with an appropriate welding mask. The arc and welding
spatters burn unprotected skin. When welding, always use protective gloves
and clothing.
2.2. SAFE USE OF THE WELDING GUN
Parts of the machine, such as the end of the ller wire and welding gun, become
burning hot during use. The wire is also sharp and moves quickly, so be careful
when threading it to place.
Never carry the machine on your shoulder during welding, but place it on an
even surface. Also, do not store the machine by hanging it from the shoulder
strap. The shoulder strap is for carrying only.
Do not keep the machine near or on hot objects, as the plastic cover may
melt.
Do not move the shielding gas bottle when the control valve is in place. Fix the
gas bottle securely in an upright position to a separate wall rack or bottle cart.
Always close the gas bottle after use.
2.3. FIRE SAFETY
Welding is always classied as hot work, so pay attention to re safety
regulations. Protect the environment from welding spatters. Remove
inammable material, such as burning uids, from the vicinity of the welding
site and supply the site with adequate re-ghting equipment.

Take into account dangers caused by special workplaces, such as re risk and
danger of explosion, when welding container-like pieces.
NOTE! Fire caused by sparks may brake out even after several hours!
CAUTION! Welding in inammable and explosive sites is strictly
forbidden!
2.4. SUPPLY VOLTAGE
• Do not take the welding machine inside a workpiece, for example in to a
container or a car.
• Do not place the welding machine on a wet surface.
• Change faulty cables immediately for they are life-threatening and may
cause a re.
• Ensure that cables are not squeezed or in contact with sharp edges or a hot
workpiece.
2.5. WELDING CIRCUIT
• Insulate yourself from the welding circuit by using dry and undamaged
protective clothing.
• Do not work on a wet surface.
• Do not use damaged welding cables.
• Do not place the welding gun or earthing clamp on the welding machine or
other electrical device.
2.6. WELDING FUMES
Make sure ventilation is sufcient. Take special precautions when welding
metals containing lead, cadmium, zinc, mercury or beryllium.
Supply of sufcient clean air can also be ensured with the use of a fresh air
mask.

3. MACHINE USE
The machine is delivered ready for operation without adjustments with 0.8 mm
diameter ller wire.
If you use different thickness ller wire, make sure that the feed roll groove,
welding gun contact tip and machine polarity are suited for the used wire size
and type. If you mainly use aluminium or stainless steel wire, we recommend
you change the wire guide to a plastic one which is better suited for the wire
type.
3.1. BEFORE IMPLEMENTATION
The products are packed to durable packages especially designed for them.
However, always make sure before use that the products have not been
damaged during transportation. Check also, that you have received the products
you ordered and the instruction manuals needed. Product packing material is
recyclable.
Transportation
The machine should be transported in an upright position.
NOTE! Always move the welding machine by lifting it from the handle.
Never pull it from the welding gun or other cables.
Environment
The machine is suitable for both indoor and outdoor use, but it should be
protected from heavy rain and sunshine. Store the machine in a dry and clean
environment and protect it from sand and dust during use and storage. The
recommended operating temperature range is -20°C – +40°C.
Place the machine in such a way that it does not come in contact with hot
surfaces, sparks and spatters.
Make sure the air ow in the machine is unrestricted.

3.3. CABLE CONNECTIONS
Connection to the mains
The machine is equipped with a 3.3 m long supply voltage cable and plug.
Connect the supply voltage cable to the mains.
NOTE! The fuse size needed is 16 A delayed.
If you use an extension cord, its cross-sectional area should be at least as large
as the supply voltage cable’s (3 x 2.5 mm²). The maximum length for the
extension cord is 50 m.
The machine can also be used with a generator. The minimum power for the
generator is 4.2 kVA, and the recommended power 8.0 kVA in order for the
machine to be used at maximum capacity.
Earthing
The earthing cable is already connected to the machine. Clean the workpiece
surface and x the earthing cable clamp to the piece in order to create a closed
and interference-free circuit needed for welding.

Welding gun
The welding gun is already connected to the machine. The welding gun leads
the ller wire, shielding gas and electric current to the weld. When you press
the welding gun trigger, shielding gas ow and wire feed begin. The arc ignites,
when the ller wire touches the welded piece.
The factory-installed wire guide in the welding gun is best suited for steel
wire welding. However, it can temporarily be used for stainless steel wire
and aluminium wire welding. Then, however, friction is greater and thus the
wire feed may tangle. If you mainly use stainless steel or aluminium wire, we
recommend you change the wire guide to a plastic wire guide.
The gun neck can be rotated 360°. When turning the neck, always make
sure that the neck is twisted almost all the way to the bottom. This prevents
damaging and overheating the neck.
NOTE! If you use other than 0.8 mm diameter ller wire, change the
welding gun contact tip to match the wire thickness.
Shielding gas
The shielding gas used for steel wires is carbon dioxide or a mixture of argon
and carbon dioxide which replaces air in the arc’s area. Shielding gas for
stainless steel wires is a mixture of argon and carbon dioxide (2%) and argon
for aluminium wires. Thickness of the welded sheet and welding power dene
the ow rate of the shielding gas.
The machine is delivered with a 4.5 m long shielding gas hose. Connect the
bayonet socket of the shielding gas hose to the machine’s hose connector and
the hose connector end to the gas bottle’s control valve.
