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 fluctuation 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 filler 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, efficient 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 first select the filler 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.

You can use steel (solid or cored wire), stainless steel, aluminium and CuSi as filler 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.

1.2.2About welding

In addition to the welding machine, welding outcome is influenced 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 filler wire that is directed to be used in reverse polarity, electrode negative. When a filler wire is loaded to the machine, the wire feed mechanism drives the filler wire through the contact tip mounted in the welding gun, and thus transfers electrical power from the contact tip to the filler 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 filler wire touches the work piece a short circuit occurs, forming the needed closed electrical circuit, an arc is formed and welding commences. Unrestricted current flow is possible only when the earth return clamp is properly attached to the workpiece and the fixing 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 filler wire. Argon + 2 % CO mixture is suitable for stainless steel wires. Argon is suitable for welding aluminium and CuSi wires. Some filler 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 fire and explosion.

2.1Unpacking

When machine leaves factory, it is set up for use with 0.8 mm diameter filler wire. If you wish to use an alternative thickness filler 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 filler 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 flow in the machine is unrestricted.

2.2Positioning and location of the machine

Place the machine on a firm, dry and level surface. Where possible, do not allow dust or other impurities to enter the machines cooling air flow. Preferably site the machine above floor 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.

2.3Distribution 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.

2.4Serial number

The serial number of the unit is marked on the rating plate. The serial number makes it possible to trace product manufacturing series. You might need the serial number when placing spare parts orders or when planning maintenance.

2.6Cable connections

Connection to the mains

The machine is fitted with a 3 m long supply voltage cable and plug. Connect the supply voltage cable to the mains. Should you need to fit 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 fix the earth return clamp to the work piece in order to create a welding circuit.

Welding gun

The welding gun is already connected to the machine. The filler 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 flow and filler wire feed begins. The arc ignites when the filler 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 filler 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 finally lead into failure of filler wire delivery.

If you mainly use aluminium or stainless steel filler 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 different 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 filler wire, change the welding gun contact tip, gun liner, and drive roll to match the selected filler wire type and thickness.
