FusoFlex

Ultimate-16(Extra):

Hydrogen-controlled electrode for all position welding. Modified lime-fluoride type covering to permit joining and repair-welding of numerous "difficult to weld" steels, especially cast steels, containing higher levels of carbon and sulphur. Also suitable for low alloy steels, cold rolled steels.Welds are of radiographic quality. Weld metal is characterised by high resistance to cracking, because of (a) the favourable combination of ductility & toughness, (b) a fairly high degree of tolerance to impurities, (c) very low hydrogen content.

Notes on usage:

Use DC(+)
Redry electrodes at 300°C -350°C for two hours.
Use short arc to the extent possible.
Minimise weaving.
These precautions become necessary for the very nature and field of application of this electrode.
