Insulator

Uses an arc between a continuous filler metal electrode and the weld pool to produce a fusion together of the base metal

It relies on a non-consumable tungsten electrode while shielding the weld with a continuous stream of water rather than a shielding gas.

It applies high-frequency electrical resistance directly between two overlapping sheets of metal without using any filler material or shielding.
