voltage characteristic (Fig. 5.6) but can have a ‘drooping’
or constant current characteristic (see Fig. 5.3) in certain
applications.
Consumables
Consumables consist of reel-mounted bare wire or flux-cored
electrodes and granular fluxes.
Fluxes
The main types of SAW fluxes are agglomerated or fused.
Agglomerated fluxes are of light colour, globular and of
irregular size. They are easily crushed and feel dry and smooth
to the touch. Deoxidisers and additional alloying elements are
added during manufacture. They are also hygroscopic
