Abstract

The invention relates to an EIGA coil (10) for partial melting an electrode (40). The EIGA coil (10) comprises a plurality of windings (12A, 12B, 12C) which are coaxially arranged with respect to a center axis (M) and axially spaced from each other, wherein each of the plurality of windings (12A, 12B, 12C) is formed in the shape of a ring interrupted by a gap (14A, 14B, 14C) and equidistant with respect to the center axis (M) and extending in a plane perpendicular to the center axis (M). Adjacent windings (12A, 12B; 12B, 12C) of the plurality of windings (12A, 12B, 12C) are respectively connected to each other via a connecting portion (20AB, 20BC; 120AB, 120BC).
