Ferromate:

FERROMATE represents a remarkably good combination of pleasing operating characteristics in all positions,weld metal soundness and higher welding output.Some characteristics are:

Easy striking and resiting of arc
Very stable and smooth arc even on low OCV(45V)
Easy and controlled flow of weld metal
Very low spatter
Medium penetration
Excellent slag detachability
Regular beads of good finish
Metal recovery of 110%-115%

Identification:Name Printed

Applications:Heavy structures like crane and bridges, assembly for earthmoving equipments, heavy machinery parts etc.

Notes on usage:

Employ welding currents within the range results in increased spatter,undercut and uneven slag covering. Furthermore, it adversely affects the quality of weld metal.
Exposure at high relative humidity, such as during rainy seasons, is likely to cause excessive mositure pickup by the covering. This in turn may affect the usual satisfactory performance and may even result in some porosity. Hence in such a case, redry electrodes at 100°C-120°C for 30-60 minutes,keeping in mind that the redrying schedule should not to be too rigourous for this class of electrodes.
As the elctrode permits touch welding, this aspect may be used to best advantage wherever practicable.1
