Soldering is accomplished by quickly heating metal parts. solder is a metal that is melted to join metallic surfaces together. common solder formulations based on tin and lead are listed below. the fraction represents percentage of tin first, then lead, totaling 100%.

tin/lead melting point (°c)
40/60 230 °c
50/50 214 °c
60/40 190 °c
63/37 183 °c
95/5 224 °c

with the same soldering iron, assuming the soldering iron’s highest temperature is 204 degrees centigrade, would you be able to make the repair if you had solder made of 50/50?
