Regular-s:

For superior welds of X-ray quality of mild steel,REGULAR-S represents a remarkably good combination of operating characteristics and weld metal soundness for welding in all positions with easy striking and restriking of arc, very stable and smooth arc even on low OCV (45V) easy and controlled flow of weld metal,very low spatter,medium penetration and regular beads of good finish.

IS:814-2004 : ER 4211X

Identification:Name Printed

Applications: Ideally suited for welding of pipelines and boiler tubes. A very wide range of jobs can be tackled effectively with REGULAR-S. Typical applications are: Tanks, Trawlers, Machinery construction, Bridges, Ships, Dredgers,Rail coaches & wagons,Sheet metal work

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 of high relative humidity, such as during rainy season, is likely to cause excessive moisture 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 be too rigorous for this class of electrodes.
