Welding supplies help ensure welding projects are finished safely and efficiently. Equip workers with a heavy-duty welding helmet to keep the eyes, face and neck protected from extreme heat, flying sparks and both infrared and ultraviolet light. Helmets are especially needed when using arc wielding rods, which can deeply penetrate metals. A welding regulator is also essential to welding safety as it allows you to monitor gas mixtures and control temperatures so you can deploy the proper amount of heat for your welding project.
