Our introductory BD-10 model is intended for light/intermittent use while our BD-50/BD-60 models are more suited for continuous heavy duty use. Our model BD-40 has limited voltage output suitable for thin/sensitive linings. Each model comes with a detachable pointed electrode tip. Other types of electrode accessories are available.
