Ultimate-14 MDF:

ULTIMATE-14 MDF represents a remarkably good combination of operating characteristics and weld metal soundness for welding in all positions, except vertical top to bottom.
easy striking and restriking of arc
very stable and smooth arc
easy and controlled flow of weld metal
very low spatter
medium penetration
self-peeling slag in most cases

Identification:Name Printed

Applications:Ideally suited for welding of pipelines, boiler tubes & particularly for joining relatively thin sections. Suitable for carbon steels in jobs involving service temperatures up to 450°C Typical applications are:Tanks Rail coaches & wagons, Scrubbing towers & cooling stacks of gas cleaning plants; sheet metal work in general.

Notes on usage:

Employ welding currents within the range recommended. Welding with excessive current 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 moisture pick-up 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 70°C-100°C for 30-60 minutes, keeping in mind that the redrying schedule should not be too rigorous for this class of electrodes.
