What type of equipment should be tested for proper functionality before welding?

Before starting any welding operation, it is essential to test equipment for proper functionality to ensure safety and effectiveness. Welding helmets are crucial as they protect the welder's eyes and face from harmful radiation, sparks, and heat generated during the welding process. Ensuring the helmet is in proper working condition, with a functional auto-darkening feature or appropriate tint, is critical for the welder's protection.

Similarly, angle grinders are commonly used in preparation and finishing processes in welding. They must also be inspected to confirm that they are operating properly, with functional safety guards and the appropriate wheel installed to prevent malfunction or accidents during use.

Testing both welding helmets and angle grinders helps prevent workplace accidents and injuries, making it clear that both pieces of equipment deserve attention before welding work begins.
