Prior to making a purchase, make sure of the following two things:. 350°C is the minimum temperature for soldering.
2. Ensure that one solder joint is welded in 3–4 seconds.
Lead-free soldering stations have the potential to guarantee the first two points. If the soldering temperature is increased against advice in order to achieve the promised soldering speed, the solder joints' quality will suffer, and the soldering iron's tip's lifespan will be shortened.
Typically, lead-free soldering stations come in 80W, 100W, 120W, and 150W power ranges. The majority of solder joints may be soldered using a lead-free soldering station with 80W of solder joints. A lead-free soldering station with a higher power can be chosen if the solder joints are too big.
To summarize, the above two requirements must be met when buying a lead-free soldering station (soldering iron). If the following two requirements are not met, a lead-free soldering station (soldering iron) cannot be referred to as a true lead-free soldering station (soldering iron).
