Lincoln Bester 7018 Basic, 2.5mm x 350mm Coated Electrode, 0.5Kg 22pcs Blister Pack.
The coated electrode consists of a metallic core centred within a coating. The diameter and the length of a rod are defined by the dimensions of its core.
The coating in the electrode is responsible for protecting the liquid weld pool, it can also provide alloying elements that increase the properties of the weld material.
The coated electrode serves to create the electric arc. As it melts, it fully contributes to forming the weld bead. Its coating also protects the weld pool and the weld bead by forming the slag.
Applications:
Actions involving metal-on-metal wear.
- Basic electrode ideal for light-duty construction work
