1.2 Product introduction
MinarcMig Evo 170 and 200 are easy-to-use MIG/MAG welding machines suitable for
professional industry, site and repair welding. Before use or doing any maintenance work on
the machine, read the operating manual and keep it for further reference.
MinarcMig Evo tolerates input voltage uctuation and is suitable for work on sites using
power generators and use with long power cables. The power source utilises PFC technology,
ensuring optimum usage on single phase power supplies. The IGBT inverter design delivers
reliable arc ignition and welding performance, with all ller wire types.
Welding and earth return cables are supplied in the delivery package, including gun, earth
clamp and connections.
1.2.1 Properties
The welding machine is small, ecient and light. It is easy to carry with the handle or shoulder
strap. It is suitable for a wide range of welding applications, and the possibility to use long
power extension cables makes it easy to use in worksite conditions. It is also suitable for use
with power generators.
The MinarcMig Evo 170 is set manually, with separate control for wire feed speed and voltage.
MinarcMig Evo 200 machine has both an automatic and manual operation 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 knob, according to the thickness of
the sheet to be welded. 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 an LCD display which indicates the welding current, welding
voltage and wire feed speed.

EN
You can use steel (solid or cored wire), stainless steel, aluminium and CuSi as ller wire in the
machine. The steel wire can be 0.6 mm, 0.8 mm, 0.9 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, the aluminium wire 1.0 mm and CuSi wire 0.8,
0.9 and 1.0 mm.
1.2.2 About welding
In addition to the welding machine, welding outcome is inuenced by the work piece to be
welded, welding technique and the welding environment. Therefore, recommendations in this
manual must be followed.
During welding, an electric welding circuit is created between the positive and negative
poles of the machine. On delivery, the welding gun is connected to the positive pole of the
machine terminals. The terminals are located inside the case door and should not be changed
unless you intend to run a ller wire that is directed to be used in reverse polarity, electrode
negative. When a ller wire is loaded to the machine, the wire feed mechanism drives the ller
wire through the contact tip mounted in the welding gun, and thus transfers electrical power
from the contact tip to the ller wire. The earth return clamp and cable (already connected to
the machine on delivery to the negative terminal) connects to the workpiece to be welded.
When the ller wire touches the work piece a short circuit occurs, forming the needed closed
electrical circuit, an arc is formed and welding commences. Unrestricted current ow is
possible only when the earth return clamp is properly attached to the workpiece and the
xing point of the clamp to the workpiece is clean, and free from paint and rust.
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 a suitable shielding
gas for steel ller wire. Argon + 2 % CO₂ mixture is suitable for stainless steel wires. Argon is
suitable for welding aluminium and CuSi wires. Some ller wires (referred to as self shielded)
form a gas shield from the burning composition of the wire’s core, thus eliminating the need
for a separate shielding gas supply.
2. BEFORE YOU START USING THE UNIT
NOTE! Please read the separate safety instruction booklet provided before you commence welding.
Pay particular attention to the risks associated with re and explosion.
2.1 Unpacking
When machine leaves factory, it is set up for use with 0.8 mm diameter ller wire. If you wish
to use an alternative thickness ller wire or type, make sure that you suitably adjust the feed
roll groove, welding gun contact tip and machine polarity for the material type selected.
If you mainly use aluminium or stainless steel ller wire, we recommend you change the wire
liner to a Kemppi plastic type, which is better suited for the material.
Always before using the equipment, make sure it was not damaged during transportation.
Also check that you have received what you ordered and that there are instructions for it.
The packaging material of the products is suitable for recycling.
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 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…+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.

MinarcMig Evo 170, Evo 200
2.2 Positioning and location of the machine
Place the machine on a rm, dry and level surface. Where possible, do not allow dust or other
impurities to enter the machines cooling air ow. Preferably site the machine above oor level;
for example on a suitable carriage unit.
Notes for positioning the machine
• The surface inclination should not exceed 15 degrees.
• Ensure the free circulation of the cooling air. There must be at least 20 cm of free space in
front of and behind the machine for cooling air to circulate.
• Protect the machine against heavy rain and direct sunshine.
NOTE! The machine should not be operated in the rain as the protection class of the machine,
IP23S, allows for outside preserving and storage only.
NOTE! Never use a wet welding machine.
NOTE! Never aim metallic grinding spray/sparks towards the equipment.
2.3 Distribution network
All regular electrical devices without special circuits generate harmonic currents into
distribution network. High rates of harmonic current may cause losses and disturbance to
some equipment.
MinarcMig Evo 170 and 200 comply with IEC 61000-3-12.
2.4 Serial number
The serial number of the unit is marked on the rating plate. The serial number makes it

2.6 Cable connections
Connection to the mains
The machine is tted with a 3 m long supply voltage cable and plug. Connect the supply
voltage cable to the mains. Should you need to t an alternative plug or mains cable, ensure
installation is completed by an authorised electrician.
NOTE! The fuse size needed is 16 A delayed.
If you use an extension cable, its cross-sectional area should be at least as large as the
machines supply cable (3 x 1.5 mm²). It is recommended to use 3 x 2.5 mm² extension cable.
The maximum length for the extension cable is 100 meters.
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.
Earth return
The welding circuit earth return cable is already connected to the machine. Clean the
workpiece surface and x the earth return clamp to the work piece in order to create a
welding circuit.
EN
Welding gun
The welding gun is already connected to the machine. The ller wire, shielding gas and
electric current is delivered to the weld inside the welding gun cable. When you press the gun
trigger, shielding gas starts to ow and ller wire feed begins. The arc ignites when the ller
wire touches the work piece. Inside the gun cable there is a factory-installed wire liner that
is best suited for welding with steel and CuSi ller wires. It can temporarily be used also with
stainless steel and aluminium wires. However, this is not recommended because of greater
friction and reduced welding performance, and it may nally lead into failure of ller wire
delivery.
If you mainly use aluminium or stainless steel ller wire, we recommend that you replace the
wire liner with a Kemppi plastic type, which is better suited for the material. For instructions
on how to change the wire liner, please refer to the Maintenance section later in this manual.
The gun neck can be rotated 360° to suit dierent welding positions. The neck is connected via
a standard clockwise screw thread. Always make sure that the neck is almost fully connected
to the bottom thread. This prevents damaging and overheating the neck.
NOTE! If you intend to use other than 0.8 mm diameter steel ller wire, change the welding gun
contact tip, gun liner, and drive roll to match the selected ller wire type and thickness.

MinarcMig Evo 170, Evo 200
Shielding gas
Shielding gas is used for replacing air around the welding arc. For steel wires, use CO₂ (carbon
dioxide) or a mixture of Ar (argon) and CO₂ for shielding gas. Welding performance will be
improved when using mixed gas products. For stainless steel wires, use mixture of Ar and
CO₂ (2 %), and for aluminium and CuSi wires, use pure argon. The required ow rate of the
shielding gas is determined by the thickness of the welded sheet and the used welding power.
The machine is delivered with a 4.5 m long gas hose. Connect the supplied female snap
connector of the gas hose to the machine’s male connector. Connect the other end of the gas
hose to the gas cylinder via a suitable and approved single stage regulator valve, where outlet
ow rates can be adjusted.
NOTE! Never attempt to connect directly to a compressed gas cylinder. Always use an approved
and tested regulator and ow meter.

MinarcMig Evo 200 automatically sets the machine based on your input selections for plate
thickness in mm, weld shape and material type. The material thickness graphic display shows
the selected plate thickness to be welded. Your machine is automatically set for welding
following these parameters inputs.
As you make your selections you will see the displayed parameters change. For example,
as you adjust the power/plate thickness control, you will see the graphic indicating plate
thickness become thicker or thinner.
The selected operating mode and material type are also shown on the display. The display
also shows a recommendation for shielding gas and ller wire diameter for the material in
question. During welding, the graphical display shows that wire feeding is active including
the wire feed rate. Of all the welding parameters, only ller wire feed speed is visible on the
display all the time. Welding voltage and welding current are only visible on the display during
welding. The last used values remain on the display until welding is restarted or parameter
settings are changed.
When adjusting the arc length, weld shape, or voltage control, the voltage display shows
a comparative scale (-9…0…9) which will disappear from the display after a preset time
following adjustment.

2.8.2 Welding power adjustment in automatic mode
Adjusting the welding power according to sheet thickness aects simultaneously both wire
feed speed and amount of current delivered to the ller wire. This is a good starting point
for welding in dierent operating situations. However, welding joint type and root opening
may inuence the amount of welding power required. Select the correct welding power
using the power control, whilst viewing the graphical display of the llet weld and sheet
thickness indicator. If the llet weld’s sheets are of dierent thickness, use their average as a
default parameter and test weld. The sheet thickness display is given in millimetres and with
steel and stainless steel wires, is based on 0.8 mm ller wire diameter. When using a 0.6 mm
ller wire, set the welding power control slightly higher than the used sheet thickness and
correspondingly slightly lower with 0.9–1.0 mm wires. With aluminium wires, the welding
power adjustment is based on 1.0 mm wire diameter.

2.8.3 Arc length trimmer in automatic mode
The arc length/weld shape/voltage trimmer adjusts the length of the arc, either shorter or
longer, and aects the welding temperature. A shorter arc is colder and a longer one hotter.
The arc length trimmer also aects the arc’s welding properties and inuences weld spatter
with dierent combinations of ller wire diameters and shielding gases. The trimmer range is
-9...0...9: negative values shorten and positive values lengthen the arc. The trimmer is preset at
0 which is, in most cases, a suitable basic setting.
If the weld is too convex, the arc is too short or cold. Then adjust the arc longer or hotter by
turning the control clockwise.
If, on the other hand, you want to weld with a colder arc to prevent for example the parent
material from burning through, adjust the arc shorter by turning the control counter
clockwise. You can also adjust the welding power, if needed.
When adjusting the arc length, the cross sectional weld joint graphic on the machines display
changes correspondingly to either a more concave, at or convex weld result.
NOTE! When welding for the rst time, we recommend that you set the arc length trimmer to 0.

button (Arc Dynamics control on MinarcMig 170 model) once to pre-select either arc dynamic
value I or value II. Changing between setting I and setting II will adjust the short circuit
characteristics to suit dierent welding applications.
2.8.5 Adjustments in manual mode
In manual mode, the wire feed speed and welding voltage are both adjusted separately.
Welding current and power are dened according to wire feed speed. The desired arc and
welding properties can be reached by adjusting the voltage.
2.9 MIG/MAG welding
NOTE! Welding fumes may be dangerous to your health. Ensure that there is ample ventilation
during welding! Never look at the arc without a face shield specically designed for arc welding!
Protect yourself and your surrounding area from the arc and hot welding spatter!
NOTE! Always wear protective clothing, gloves, face and eye shields suitable for welding. It is
recommended that you make practice welds before you commence welding your main work piece.
NOTE! The work piece will be very hot. Protect yourself and others at all times.
You can start welding after you have made the necessary preparation described throughout
these instructions.
Providing you ensure that the MinarcMig Evo equipment is correctly prepared and set for
the material type and joint to be welded, you will achieve exceptionally high quality welding
results.
• Ensure that the correct ller wire type and size is selected for the work piece.
• Ensure that the correct wire liner and contact tip size is tted to the welding gun.
• Ensure that the correct shielding gas type is connected and the ow rate adjusted before
welding starts.
• Ensure the earth return clamp is connected to the work piece
• Ensure that you are wearing the correct safety equipment before you start welding
- including: suitable welding clothing, the correct welding face shield with a suitable
shade welding lens, welding gloves and when necessary, a welding mask.
NOTE! Please read section 1.2.2 before proceeding further.

Having checked that the MinarcMig Evo is prepared in the correct way for the welding task
ahead, and that you are wearing the necessary protective equipment, you are ready to
commence welding.
MIG/MAG welding can be performed down hand, vertically and overhead: either right to left
(Right handed operators) or left to right (left handed operators)
First, present the welding gun nozzle to a practice work piece. The gun nozzle should be
approximately 15 mm away from the surface of the work piece and weld joint. If welding a T
llet joint, the gun should be held at an angle of approximately 45 degrees, bisecting the 90
degree joint at the midway point. Starting at the right hand side of the joint (Right handed
operators only), lean the gun backwards slightly, so the gun nozzle is pointing forwards,
towards the centre of the work piece. This is called a 'pushing technique' and is suitable for
most applications.
Pull the welding gun trigger. The ller wire will move forward, and a short circuit will occur
and the arc will be established. Keeping the gun trigger depressed, the molten weld pool will
start to form. Begin to travel the gun forwards, in a controlled manner and travel speed. Not
too fast and not too slow. Providing you have correctly set your MinarcMig Evo, your welding
power should be correctly set for the material thickness and type, and the quality of your weld
deposit is now determined by your skill and technique.
The resulting weld deposit, width and shape, should be consistent in appearance and quality.
If you are welding too fast the weld bead may be too thin or even intermittent in appearance.
Try to slow your travel speed slightly and maintain an even approach to the joint. If you are
welding too slowly, you may nd the weld deposit is too heavy, the weld piece overheats and
possibly burns a hole through the plate. All that may be required to ensure a successful result
here is an increase in forward travel speed, but you may also need to reduce the power setting
slightly, to achieve the desired result.
As with all craft skills – practice will make perfect! For more info www.kemppi.com > Welding

Service the wire feed mechanism at least every time the spool is changed.
• Check the wear of the feed roll groove and change the feed roll when necessary.
• Carefully clean the welding gun wire liner with dry compressed air.
NOTE! When using compressed air pistols, ensure you are wearing adequate safety equipment
including, suitable work clothing, gloves and eye protection. Never direct compressed air pistols or
the end of the liner at your skin, face or others in the vicinity.
Cleaning the wire liner
Pressure of the feed rolls remove metal dust from the ller wire’s surface which then travels
in the wire liner inside the gun cable. If the wire liner is not cleaned, it gradually clogs up,
increasing drag, impairing wire feed performance and weld quality. Ultimately this will cause
wire feed malfunctions. Clean the liner in the following manner:
1. Remove the welding gun’s gas nozzle, contact tip and contact tip adapter.
2. With a pneumatic pistol, blow dry and ltered compressed air through the wire liner.
3. Clean the wire feed mechanism and spool housing with compressed air.
4. Reassemble the welding gun. Firmly tighten the contact tip and contact tip’s adapter.
Replacing the wire liner
If the wire liner is too worn or totally clogged, replace it with a new one according to the
following instructions. You should also replace wire liner with a plastic one, if you mainly use
stainless steel or aluminium wire.
1. Disconnect the welding gun cable from the machine as follows.
a. Disconnect the gun's power cable xing clamp by opening the screws.
b. Disconnect the gun's power cable from the machine’s pole.
c. Disconnect the connector of the trigger conductors from the machine.
d. Open the gun’s mounting nut.
e. Extract the gun gently from the machine whereupon all parts come through the
cable hole.
2. Open the mounting nut of the wire liner, which exposes the end of the wire liner.
3. Straighten the welding gun cable and withdraw the wire liner from the gun cable.
4. Push a new wire liner into the gun. Make sure that the liner enters all the way into the contact
tip’s adapter and that there is an O-ring at the machine end of the guide.

5. Tighten the wire guide in place with the mounting nut.
6. Cut the wire guide 2 mm from the mounting nut and le the sharp edges of the cut round.
7. Reattach the gun in place and tighten the parts to spanner tightness.
3.3 Troubleshooting
Problem cause
The wire does not
move or wire feed
entangles
The main switch
indicator will not
light up
Poor welding results Several factors aect the welding quality
Overheating indicator
is illuminated
Feed rolls, wire liner or contact tips are defective
• Check wire mechanism adjustment is not too tight or too loose
• Check that the feed roll groove is not too worn
• Check that the wire liner is not blocked
• Check that the contact tip and wire liner are suitable for the wire size used
• Check that spatter is not blocking the contact tip and that the hole is not closed or damaged
• The machine has no supply voltage light
• No electricity connected to the machine
• Check the mains supply fuses
• Check the mains cable and plug
• Check that the wire feed is constant
• Check the trimming settings of welding power control and arc length
• Check the material selection setting
• Check that the earth return clamp is xed properly, xing point is clean, and both cable and its
connections are undamaged
• Check that the shielding gas is suitable for the wire material used
• Check the ow of shielding gas from the tip of the welding gun
• Supply voltage is uneven, too low or too high
The machine has overheated
Normally, this indicates that the device has reached its maximum designed operating temperature.
The thermostat has become active, switching the welding power o. Allow the unit to cool and the
machine will soon automatically reset and allow welding to restart.
• Ensure that cooling air has unrestricted ow.
• If the machine’s duty cycle has been exceeded, wait for indicator to turn o.
In certain circumstances, this light may also indicate irregularity in the supply voltage.
Too low or high supply voltage.
