ESAB OK 48.00 welding electrodes, which are used as welding rods for arc welding (Manual Metal Arc welding).
Name: The product is called ESAB OK 48.00.
Purpose: They are low-hydrogen electrodes primarily used for general-purpose arc welding of mild and low-alloy steels. They produce strong welds with minimal risk of hydrogen-induced cracking. The "Vac Pac" packaging visible in the image is vacuum-sealed to ensure the electrodes remain moisture-resistant until used.
