In fact, the welding temperature is mainly different. The welding temperature required by lead-free tin wire is higher, generally around 250 degrees, while the welding temperature of ordinary tin wire is 180 degrees, so the welding temperature of lead-free soldering station is higher and the heating speed of lead-free soldering station is faster. Of course, there are exceptions. Among lead-free solders, there are also low-temperature solders, which have a lower melting point than lead solders. However, the price of this low-temperature solder is quite expensive.

Theoretically speaking, lead solder joints can also be welded with lead-free soldering platform, because the temperature of lead-free soldering platform can reach the melting point of lead solder. But in fact, no one uses it like this, because once lead solder is used to weld on the lead-free soldering platform, the lead-free soldering platform is polluted and can no longer be used as a lead-free environmental protection product.

On the other hand, lead-free solder can not be welded with lead soldering station, because the temperature of lead soldering station may not reach the melting temperature of lead-free solder
