1. PREFACE
1.1 GENERAL
Congratulations on choosing the MinarcMig Adaptive 170 equipment. Used
correctly, Kemppi products can signicantly increase the productivity of your
welding, and provide years of economical service.
This operating manual contains important information on the use,
maintenance and safety of your Kemppi product. The technical specications
of the equipment can be found at the end of the manual.
Please read the manual carefully before using the equipment for the rst
time. For your own safety and that of your working environment, pay
particular attention to the safety instructions in the manual.
For more information on Kemppi products, contact Kemppi Oy, consult an
authorised Kemppi dealer, or visit the Kemppi web site at www.kemppi.com.
The specications presented in this manual are subject to change without
prior notice.
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, ecient and extremely light. It is easy to
carry with the help of a shoulder strap. The machine is suitable for a range
of dierent 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
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.

2.2 GENERAL VIEW OF THE MACHINE
1. Welding gun
2. Earthing cable
3. Main switch
4. Supply voltage cable
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 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.

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
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.
