Flux type suitability is strongly dependent on its application. In combination with the wire electrode the most suitable flux should match the requirements of the plate material as closely as possible under the existing welding conditions. Further information can be obtained from the technical flux data sheets.

Coils, spools, drums and spiders as standard package forms for SAW-wire electrodes, different package forms on request.
