Analysis of Common Faults in welding head

1. welding head doesn't heat up after electrifying, welding head doesn't heat up after electrifying, which indicates that welding head has open circuit defect. This defect may occur at several plugs in welding head, where the soldering iron core is broken, the lead wire of the soldering iron core is open, and the power cord of welding head is open. 

2. Electrification of welding head in welding head is very dangerous for welders, which will lead to electric shock. Therefore, once the electrification of welding head is found, the power supply should be blocked immediately for inspection. There are several reasons why welding head is charged: welding head power cord is connected to the terminal of grounding wire; After the power cord falls from the soldering iron core terminal, it touches the screw of the grounding wire again, causing electric leakage caused by the lead of the live power supply in welding head; Electric leakage of power ground wire itself. 

3. welding head doesn't eat tin, welding head doesn't eat tin. "Xi Pu sees that the newly bought welding head is directly used without trimming, which leads to welding head not taking tin. Welding head used for a long time is not tin-plated, welding head. Burned to death, it needs to be trimmed. 

4. The welding head presents pits. When the welding head is used for a period of time, the welding head presents pits or oxidation corrosion layers, which changes the shape of the blade surface of welding head. In this case, the oxide layer and pits can be filed off with a file, and the original shape can be filed, and then plated with tin, which can be used from the beginning.
