Excelloy 52 AC/DC ±:

For rusty and dirty steels, a superior, all position, all purpose maintenance electrode

The Excelloy 52 was specially designed for easy all position operation on rusty, dirty, or painted steels. The forceful arc drive produced by this electrode burns through weld zone contamination, depositing a deeply penetrating, porosity free weld.


Applications

General welding of all structural steels and mild steel pipe. Ideal for use on painted and plated surfaces as well as tack welding and every day maintenance welding. Works well where fit up is poor or when slag interference must be minimized. Exceptional ability to operate under severely adverse conditions.


Procedure

Clean weld zone with grinder and wire brush. Gouge out damaged material with Excelloy 56. DC+ (reverse polarity) produces deep penetration; DC-(straight polarity) will limit penetration and flatten weld bead. AC prevents arc blow. A medium arc length should be maintained when using either stringer or weave beads.
