Matters needing attention in welding of Weile welding head

Matters needing attention in the welding of Weile welding head: 

(1) Low temperature welding should be used as far as possible in the welding of photovoltaic modules. The temperature required for lead-free tape is 400℃, and its oxidation speed is twice that of 370℃. 

(2) welding head should be coated with tin layer at any time to prevent oxidation.

 (3) During welding, do not exert excessive pressure on the soldering iron to prevent the welding head from being damaged and deformed. During welding, only welding head can touch the solder joints sufficiently, and the heat can be transferred abundantly. Choosing the right welding head can also achieve better results.

 (4) When the welding operation is not carried out for a long time, the power supply of the welding table should be turned off.

(5) Prepare a clean sponge soaked with water before using the soldering iron, and scrub the Willard welding head after squeezing out excess water. 

(6) When welding, the force should be uniform, not too strong, and should be appropriate with the self-gravity of the electric iron.

 (7) The soldering tape soaked with flux cannot be exposed in the air for too long. When white powder appears on the surface, it should be soaked again. 

(8) The electric soldering iron is in a high temperature state in use, so pay attention to placing it so as not to burn yourself and others. (9) The soldering iron should be placed on the soldering iron rack after being used, and it is not allowed to be placed at will, so as not to burn the goods.
