NOTE!
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,

About welding

EN
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
influenced 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 influenced 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 flow is possible when the
earthing clamp is properly attached to the workpiece and the fixing point of the clamp on the
workpiece is clean, paintless and rustfree.
