I believe that everyone has encountered the situation that lead-free welding head is stained with tin. Today, Xiaobian is like introducing the solution of tin-free soldering iron head:

 

If the lead-free soldering iron head is stained with tin, it will directly affect its use. This requires us to adopt methods to avoid tin staining in the normal maintenance process. This requires us to deal with it from two aspects: prevention and solution.

Prevention of tin on lead-free soldering iron head

1. welding head shall remove the residual oxide, dirt or flux on the welding head before sending power every day; And remove impurities from the heating body to prevent the welding head from being stuck with the heating body or sleeve.

2. When using, first set the temperature at about 200℃ for preheating, and then set it to 300℃ when the temperature reaches.

3. During welding, the soldering iron nozzle shall not be forced to pick or squeeze the object to be welded, nor shall it be welded by friction.

4. Do not use objects with rough surfaces to rub the welding head, and do not add any compound to the tin-stained surface.

 

 

Solve the problem of tin staining on lead-free soldering iron head

If the welding head has been stained with tin, it can be gently wiped with 600-800 mesh sandpaper, and then wrapped around the wiped tin-stained surface with tin wire containing flux, heated and melted, and then added with tin again.

Above, we introduced how to deal with the situation of tin in welding head from two aspects of prevention and solution. I also hope to help everyone.
