*Proprietary Modification:  Special specification exceeding chemistry for extreme crack resistance.

FEATURES & APPLICATIONS

Due to exceptional strength and crack resistance, it is ideal for repairing tools, dies, spring steel and any dissimilar metal combinations, except for the aluminum and copper alloys. It is also recommended for repairing worn parts and as an underlay for hardfacing.

  • The ultimate electrode for welding all types of steels, without any danger of cracking or breakage. Special “FERRITE BALANCED” Chemistry also serves as a “STUD PULL” electrode.
  • An engineered deposit chemistry that has the perfect ratio of metallics to offer crack resistance far superior to any other brand.
  • All colors are usually kept in stock unmarked.
  • Special flux formulation eliminates slag interference in horizontal fillets.
  • Slag is designed to turn to powder making this electrode ideal for “STUD PULL” applications.
  • Available in TIG form as product code 6007 and in MIG form as product code 7007.

Welding Techniques: The area in which the weld is to be made should be free of rust, grease, paint and other materials which cause weld contamination. A 90° vee joint should be used when joining heavy sections. Maintain a short arc length and use stringer beads.

Welding Positions: Flat, Horizontal, Vertical up, Overhead
