Electrode General Purpose PH28

DESCRIPTION: The WELDWELL PH28 electrode has a medium-heavy rutile coating and yields a fairly rapidly solidifying slag. This electrode is the answer where a universal rod is desired for welding in all positions. With this electrode even not so experienced welders will obtain good results since it is very easy to use. The PH28 is extremely suitable for making fi llet welds. Welding is then done with a short arc. The weld surface is very smooth and the beads are almost fl at. The same applies for unprepared butt welds and for outside corner welds. The uniform fi ne-droplet metal transfer and the possibility of using a shorter arc length without risk of short-circuiting and freezing are very helpful in both vertical and overhead welding. The PH28 may be employed on either AC or DC. When it is used with DC the electrode is normally connected to the negative pole (straight polarity). For this electrode, use can be made of transformers with a relatively low no-load voltage.
