Portable welding electrode dryer, also known as an electrode quiver or oven. [1, 2]
Function: It is a thermostatically controlled heating device used by welders to store, dry, and maintain welding electrodes at specific temperatures to prevent moisture absorption.
Capacity: Based on search results for similar yellow cylindrical models, this is likely a 5kg capacity quiver.
Features: It typically includes a handle for portability, a temperature gauge (visible in the image), and a power cable for operation
