What are the reasons for a lack of power in an electric wrench?
2 Answers
An electric wrench lacking power can be attributed to the following reasons: Motor damage: An electric wrench is a tool powered by electricity or batteries, used for tightening high-strength bolts, also known as a high-strength bolt gun. Motor damage can result in engine weakness, failing to provide power to the wrench, thus causing the electric wrench to lack power. Insufficient battery charge: The battery may have aged, leading to insufficient charge. Without power, it naturally lacks strength. Motor overheating: Prolonged use or failure to replace the motor over many years can cause faults like overheating. Motor overheating affects the output power, consequently impacting the performance of the electric wrench.
I've been using an electric wrench for several years myself, and the most common issue with a wrench losing power is battery-related. Over time, batteries age, don't charge fully, or non-original chargers cause voltage instability. Another possibility is internal gear wear—I've opened mine before and found that dust buildup or insufficient lubrication can cause operation to become sluggish. Also, if the power cord is loose, even non-battery-powered models can lose power. It's recommended to clean the wrench after each use and check the battery status, avoiding waiting until it's completely dead before recharging. If the problem persists for a long time, have it inspected by a repair service immediately to prevent further damage and work disruptions.
