Wire for repairing or changing circuit elements such as printed circuits, has heat-resistant insulation surrounded by a hot-melt adhesive. The wire is attached to the surface of printed circuit boards easily by applying a hot iron to the adhesive layer on the wire and melting the adhesive which then adheres to the board surface. The coating is applied by passing insulated wire vertically through a length of molten adhesive and then through a die. Printed circuit board modifications can be made quickly and easily and at a relatively low cost.

An electrically conductive wire, said wire comprising, in combination, an electrical conductor, a coating of relatively easily strippable insulation surrounding said conducter, and a coating of normally solid, inactive hot-melt adhesive surrounding said insulation, said adhesive being adapted to be activated by the application of heat thereto at each of a plurality of locations along its length so as to cause said wire to adhere to a substantially planar support surface at each of said locations in response to said application of heat. A method of coating insulated electrical wire with a hot-melt adhesive, said method comprising: melting a hot-melt adhesive in heated chamber, passing uncoated insulated electrical wire through said melted adhesive in said chamber, withdrawing said electrical wire vertically from said heated chamber through a die to insure uniform coating, and cooling said coating to solidify it.
