It is often used in the construction, sanitary and DIY sectors. **Q: What types of cartridge guns are there?** A: There are manual, battery-powered and compressed air-powered cartridge guns. Manual models are the most common, while battery-powered and compressed air-powered models have been developed for professional use. **Q: What does the power ratio of a cartridge press mean?** A: The force ratio describes the ratio of the manual force applied to the actual pressure force on the cartridge.
