Metalworking

Metalworking stick electrodes consist of a solid metal core wire with an extruded flux coating. The flux coating serves multiple purposes, including shielding the weld zone, ensuring arc stability, controlling penetration, and protecting the weld deposit from oxidation. Different types of flux coatings are available, such as Rutile (R, RR), Basic (B), and Cellulosic (C), each with specific characteristics and applications.

Safety 

When using stick electrodes, it is essential to follow safety measures to protect against hazards such as electric shock, fumes, and UV radiation. Proper personal protective equipment (PPE), including welding helmets, gloves, and protective clothing, should be worn. Adequate ventilation or fume extraction systems should be in place to manage welding fumes and gases.
