PREFACE 1.1 General Congratulations on choosing the MinarcMig equipment. Used correctly, Kemppi products can significantly 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 specifications of the equipment can be found at the end of the manual. Please read the manual carefully before using the equipment for the first time.
MinarcMig 180 / © Kemppi Oy / 1117 You can also use steel wire (solid or cored wire), stainless steel wire or aluminium wire as filler 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.
MACHINE USE The machine is delivered ready for operation without adjustments with 0.8 mm diameter filler wire. If you use different thickness filler 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. 2.
MinarcMig 180 / © Kemppi Oy / 1117 2.2 General view of the machine 1. 2. 3. 4. 5. EN 2.3 Welding gun Earthing cable Main switch Supply voltage cable Shielding gas hose connector 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. WARNING: This equipment does not comply with IEC 61000-3-12.
Earthing The earthing cable is already connected to the machine. Clean the workpiece surface and fix 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 filler wire, shielding gas and electric current to the weld. When you press the welding gun trigger, shielding gas flow and wire feed begin.
MinarcMig 180 / © Kemppi Oy / 1117 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 define the flow rate of the shielding gas. The machine is delivered with a 4.5 m long shielding gas hose.
Filler wire The machine is delivered with the welding gun connected to +pole making it suitable for steel solid wire, stainless steel wire and aluminium wire welding without adjustments. 2.5.1 Changing the feed roll groove The feed roll groove is factory set for welding filler wires of 0.8–1.0 mm diameter. The feed roll groove must be changed if you use 0.6 mm thick filler wire. MinarcMig 180 / © Kemppi Oy / 1117 2.5 EN 1. 2. 3. 4. 5. 6. 7. 8. Open the feed roll from the pressure control lever.
MinarcMig 180 / © Kemppi Oy / 1117 2.5.2 Threading the filler wire 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.
2.5.3 Reversing polarity Some filler wires are recommended to be welded with the gun in the –pole, so the polarity should be reversed. Check the recommended polarity from the filler wire package. MinarcMig 180 / © Kemppi Oy / 1117 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.

2.6.1 Display in automatic mode EN MinarcMig 180 / © Kemppi Oy / 1117 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 off and the yellow overheating indicator light switches on. The light switches off when the machine is ready for operation again.
MinarcMig 180 / © Kemppi Oy / 1117 display during welding. The last used values remain on the display until welding is restarted or settings are changed. When adjusting the arc length, the voltage display shows a comparative scale (-9…0…9) which will disappear from the display after some time once the adjustment is made. 2.6.
MinarcMig 180 / © Kemppi Oy / 1117 Once the arc has been trimmed, it usually does not need to be changed when the welded sheet thickness changes. 2.6.4 Display in manual mode 1. Operating mode 2. Wire feed speed chart 3. Welding values: wire feed speed, welding voltage and welding current The selected operating mode is visible on the display. During welding, the wire feed speed chart displays the wire’s speed. Wire feed speed is the only welding parameter always visible on the display.
MinarcMig 180 / © Kemppi Oy / 1117 2.7 Threading the shoulder strap EN The machine is delivered with a shoulder strap which helps carrying the machine. Thread the shoulder strap in place according to the picture. NOTE! The machine should not be hung up from the shoulder strap.
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 cables. 3.1 Daily maintenance • Remove welding spatters from the welding gun’s tip and check the condition of the parts. Change damaged parts to new ones immediately.
MinarcMig 180 / © Kemppi Oy / 1117 Cleaning the wire guide Pressure of the feed rolls remove metal dust from the filler wire’s surface which then finds 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.
Disposal Do not dispose of electrical equipment with normal waste! In observance of European Directive 2002/96/EC on waste electrical and electronic equipment, and its implementation in accordance with national law, electrical equipment that has reached the end of its life must be collected separately and taken to an appropriate environmentally responsible recycling facility.
