What are the differences between an electric wrench and a pneumatic wrench?
Pneumatic wrench, then, is primarily a tool for providing high torque output with minimal consumption. It allows a mass object to rotate at a constant speed through a constant power source, and then instantaneously hits the output shaft so that a relatively large torque output can be obtained.
An electric wrench is a wrench powered by a power source or battery. It is a tool for tightening bolts. It is mainly used in the steel structure installation industry, usually in the form of bolts.
