This wire is not coated with paraffin.
It is ideal mainly for a wire EDM machine that is used in combination with an AT unit made by Mitsubishi Electric.
This wire provides the work material with a fine finish and also realizes superior automatic threading ability.
Because the wire is not coated with paraffin, slipping of the wire is minimized, realizing stable wire feed. Very high automatic threading performance is realized when an AT unit is used with the FA series, RA90AT, or other EDM machine made by Mitsubishi Electric.
