Stainless Flux Coated TIG
These flux coredrods are primarily used for the root pass on piping where backing and purging gas may not be possible or desirable. This rodshould be used as a basic tig rodon DCEN, however caution is advised due totheeasily removable slag covering thatmust be removed prior to addition welding.
