Recommended principally for welding or electro-brazing non-ferrous metals having relatively high electrical conductivity. Cross wire welding or copper and brass wires and welding of copper wire braid to brass and bronze terminals are typical applications. Generally, special set-ups and procedures are required for this type of work.
