EN
Earthing cable
Connect the earthing cable to the negative pole in MMA welding, and to the positive pole in
TIG welding.
Before you start welding, clean the work piece surface and x the earth return clamp to the
work piece in order to create a closed and interference free welding circuit.
Welding torch (TIG)
The welding torch is used to supply shielding gas and electrical arc energy to the weld piece.
When you press the welding torch switch, the shielding gas begins to ow and the arc is
established. The TIG torch is connected to the negative pole.
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!
Prepare to weld
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. If when igniting the arc or during welding, the electrode stick’s or freezes’ to the work piece,
note that it will quickly heat up, and may start to glow red hot. To release the electrode, twist the
electrode holder away from the work piece and start again. If this fails, switch o the machine at
the main switch and then release the electrode after it has cooled down.
NOTE! The electrode and 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.
3.1 About welding
MinarcTig Evo is a precise welding tool and will provide high quality results time after
time provided the correct operational procedures are followed. Welding quality is not only
inuenced by the machine itself. Personal expertise, ancillary equipment and consumables
also play an essential role, as does the correct, fused supply power.
In addition to the welding machine, welding outcome is inuenced by the piece being welded
and the welding environment. Therefore, recommendations in this manual must be followed.
Welding is carried out when an electric arc is established between the welding electrode
and work piece. Earthing cable attached to the workpiece guides the current back to the
machine, forming the needed closed circuit. Unrestricted current ow is possible when the
earthing clamp is properly attached to the workpiece and the xing point of the clamp on the
workpiece is clean, paintless and rustfree.

3.2 Manual metal arc welding (MMA)
In Manual Metal Arc (MMA) welding the ller material is melted from the electrode to the weld
pool. The rate of welding current is selected on the basis of the welding electrode size used
and welding position. The arc forms between the electrode tip and work piece. The melting
electrode coating forms a gas and slag shield, which protects the molten metal in transfer
to the weld pool and during solidication. As the slag solidies over the hot weld metal, it
prevents weld metal oxidation. This slag coating is removed after welding e.g. with a chipping
hammer. When removing the slag coating, ensure you protect your eyes and face with suitable
equipment.
For more info www.kemppi.com > Welding ABC.
MMA welding electrodes
In MMA welding, the welding electrodes must be connected to the correct pole. Normally,
the electrode holder is connected to the positive and the earthing cable to the negative
connector.
It is also important to properly adjust the welding current so that the ller material and
coating will melt properly and the welding is ecient. The table below presents the electrode
sizes available with the MinarcTig Evo welding machine and the corresponding welding
current values.
MMA Electrodes and corresponding current settings range
The TIG process forms an arc between the tungsten electrode and the work piece. The arc
melts the work piece forming a molten weld pool. The arc and tungsten electrode mounted in
the TIG torch, are shielded by an inert shielding gas that is connected to, and ows through,
the nozzle of the TIG torch. The gas required is Argon and the ow rate is approximately 8 to
15 litres per minute. If necessary, suitable ller material is added to the weld pool to complete
the weld joint. Filler wire is fed into the weld pool from the outside of the arc and gas shield.
The ller wire and the welding current level are decided according to the base material type
and thickness, joint form and welding position. (Gas regulator, ow meter and pure argon
shielding gas are not provided in this package.)
TIG welding electrodes and gas nozzles
In DC TIG welding we recommend the use of the WC20 (grey) type electrode, however other
types are available.
The welding electrode size (diameter) is selected depending on the welding current/power to
be used. An electrode with an insucient diameter compared to the welding current will melt,
while excessive electrode size will make it more dicult to ignite the arc.
Generally speaking, a 1.6 mm tungsten electrode will cover currents up to 150 A, and 2.4 mm
tungsten electrode up to 250 A DC current.
Before use, grind the tungsten electrode to a sharp point at approximately 1.5 times the
diameter of the electrode. If the electrode touches the work piece during welding, re-sharpen
the electrode.
In TIG welding, shielding gas is used to prevent atmospheric contamination of the molten
weld pool. Normally, the shielding gas is argon (Ar), and the gas ow rate is approximately
8–15 litres per minute, but this can vary according to the welding current used and the size of
gas nozzle.
The machine is delivered with a 4.5 m long shielding gas hose. Connect the supplied female
snap connector of the shielding gas hose to the machine’s male hose connector. Connect the
free end of the shielding gas hose to the gas bottle, 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.
