What specification of solder wire for 200 Watt electric iron?
This thing can not say you see the main technical requirements of two hundred Watt High frequency soldering station. We also enterprise instantaneous maximum power 190W in high frequency is mainly iron temperature see you with so much power welding must be very large if it is welding welding so it is suggested to use 2 or more of the small tin wire welding it is used 1 or 1.2 bar welding small with 0.8 lead-free solder wire to 350 degrees to 360 the temperature mainly depends on your process requirements if choose automatic soldering machine wire harness
Generally use 2.5 solder wire, in fact, the size does not matter
According to you need to weld the electronic components and see it, if the electronic components are relatively small, with a little bit of solder wire, more easy to weld; if it is larger, then use thicker, save time
