Important notes
Items in the manual that require particular attention in order to minimise
damage and personal harm are indicated with the ’NOTE!’ notation. Read
these sections carefully and follow their instructions.
1.2 PROPERTIES
The welding machine is small, ecient and extremely light. It is easy to
carry with the help of a shoulder strap. The machine is suitable for a range
of dierent 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 ller wire. Note, however, that the machine is designed for
steel wire welding only.

2. MACHINE USE
The machine is delivered ready for operation without adjustments with
0.8 mm diameter ller wire.
If you use non-recommended 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.
2.1 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

5. Shielding gas hose connector
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 Adaptive 170:
WARNING: This equipment does not comply with IEC 61000-3-12. If it is
connected to a public low voltage system, it is the responsibility of the
installer or user of the equipment to ensure, by consultation with the
distribution network operator if necessary, that the equipment may be
connected.
2.4 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 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. Thickness of the
welded sheet and welding power dene 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.
6
1. Connect the hose to the gas bottle’s control valve and tighten the
connector.
2. Adjust the ow rate with the control valve screw. A suitable shielding gas
ow rate is 8 – 15 l/min.
3. Close the bottle’s valve after use.
NOTE! Use a shielding gas suitable for the material’s welding. Fix the gas bottle
securely in an upright position before installing the control valve.
2.5 FILLER WIRE
The machine is delivered with the welding gun connected to +pole making it
suitable for steel solid wire welding without adjustments.
2.5.1 Changing the feed roll groove
The feed roll groove is factory set for welding ller wires of 0.8 – 1.0 mm
diameter. The feed roll groove must be changed if you use 0.6 mm thick ller
wire.
1. Open the feed roll from the pressure control lever.
2. Switch the machine on from the main switch.
3. Press the welding gun trigger and drive the feed roll in such a position
that its locking screw is up and can be opened.
4. Switch the power o from the main switch.
5. Open the feed roll locking screw with a 2.0 mm Allen wrench
approximately half a turn.
6. Pull the feed roll from its shaft.
7. Turn the feed roll and reinstall it to its shaft all the way to the bottom
making sure that the screw is on the shaft’s level.
8. Tighten the feed roll locking screw.

2.5.2 Threading the ller wire
MinarcMig 170 / © Kemppi Oy / 1117
EN
1. Open the reel housing by pressing on the opening button and install
the wire reel in such a way that it rotates counter clockwise. You can
use either a 5 kg (diameter 200 mm) or 1 kg (100 mm) wire reel in the
machine.
2. Attach the reel with a reel lock.
3. Unfasten the wire end from the reel, but hold on to it all the time.
4. Straighten the wire end for approximately 20 cm and cut the wire in the
straightened location.
5. Open the pressure control lever which then opens the feed gear.
6. Thread the wire through the wire’s rear guide to the gun’s wire guide.
7. Close the feed gear and fasten it with the pressure control lever. Make
sure that the wire runs in the feed roll groove.
8. Adjust the compression pressure with the pressure control lever no
higher than to the middle of the scale. If the pressure is too high, it
removes metal fragments from the wire surface and may damage the
wire. On the other hand, if the pressure is too low, the feed gear slips and
the wire does not run smoothly.
9. Press the welding gun trigger and wait for the wire to come out.
10. Close the reel housing cover.
8
NOTE! When driving the wire in to the gun, do not point the gun at yourself or
others or put, for example, your hand in front of the tip, because the cut wire end
is extremely sharp. Also, do not put your ngers near the feed rolls, because they
might get squeezed between the rolls.
2.5.3 Reversing polarity
Some ller wires are recommended to be welded with the gun in the –pole,
so the polarity should be reversed. Check the recommended polarity from
the ller wire package.
MinarcMig 170 / © Kemppi Oy / 1117
EN
1. Disconnect the machine from the mains.
2. Bend the rubber cover of the earthing cable’s pole in such way that the
cable can be disconnected.
3. Remove poles’ tightening nuts and washers. Note the correct order of
the washers!
4. Interchange the cables.
5. Install the washers in place and close the tightening nuts to spanner
tightness.
6. Put the rubber cover of the earthing cable’s pole rmly in place. The
rubber cover must always protect the earthing cable’s pole.

1. Welding power control
2. Arc length trimmer
3. Standby indicator light
4. Overheating indicator light
The welding power is adjusted according to the thickness of the welded
sheet. The machine also has a trimmer for arc length.
Indicator lights display the machine’s standby mode and inform of a possible
overheating.
When you switch the machine on, a green standby light switches on.
Simultaneously, the main switch indicator light switches on. If the machine
overheats or the supply voltage is too low or too high, the welding operation
automatically switches o and the yellow overheating indicator light
switches on. The light switches o when the machine is ready for operation
again. Make sure that there is enough space around the machine allowing air
to freely ow and cool the machine.

10
2.6.1 Welding power adjustment
Adjusting the welding power according to sheet thickness aects
simultaneously both wire feed speed and amount of current lead to the wire.
This is a good starting point for welding in dierent operating situations.
However, connection type and root opening may inuence the amount of
welding power needed.
Select the correct parameter with the welding power control according
to the welded llet weld’s sheet thickness. If the llet weld’s sheets are of
dierent thickness, use their average as a default parameter.
Sheet thickness scale has been given in millimetres and it is based on 0.8 mm
wire diameter. When using a 0.6 mm wire, set the welding power control
slightly higher than the used sheet thickness and correspondingly slightly
lower with 0.9 – 1.0 mm wires.
NOTE! When welding for the rst time, we recommend that you set the arc length
trimmer to the middle position.
MinarcMig 170 / © Kemppi Oy / 1117
2.6.2 Arc length trimmer
The arc length trimmer adjusts the length of the arc 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
spatters with dierent combinations of ller wire diameters and shielding
gases.
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 need be.
Once the arc has been trimmed, it usually does not need to be changed
when the welded sheet thickness changes.

NOTE! The machine should not be hung up from the shoulder strap.
3. SERVICE
When servicing the machine, its utilization degree and environmental
circumstances should be taken into account. If you use the machine
appropriately and service it regularly, you will spare yourself from
unnecessary malfunctions.
NOTE! Disconnect the machine from the mains before handling the electrical

Parts of the welding gun and wire guide
Cleaning the wire guide
Pressure of the feed rolls remove metal dust from the ller wire’s surface
which then nds its way to the wire guide. If the wire guide is not cleaned, it
gradually clogs up and causes wire feed malfunctions. Clean the wire guide
in the following manner:
1. Remove the welding gun’s gas nozzle, contact tip and contact tip’s
adapter.
2. With a pneumatic pistol, blow compressed air through the wire guide.
3. Blow the wire feed mechanism and reel housing clean with compressed
air.
4. Reattach the welding gun’s parts. Tighten the contact tip and contact
tip’s adapter to spanner tightness.
