Question

Soldering is accomplished by quickly heating metal parts. Solder 19 a I 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 50/50 60/40 63/37 95/5 230 oC 214 °C 190 °C 183C 224 °C The soldering iron's highest temperature setting is 400°F. What is the soldering ron's temperature in Celsius (Centigrade)? Round your answer to the nearest degre ith the same soldering iron, would you be able to make the repair if you had sold de of 50/50? You can make the repair if the soldering iron gets hotter than the lting point listed in the table above.

Explanation / Answer

Soldering iron's highest temperature is 400 F
We aer to convert this into centigrade scale;
(F-32) /180 = (C-0)/100
When F= 400 we get
(400-32) / 180 = C/100
C= 100/180 (368) = 204.4 degrees celsius
Thus, highest temperature of 400 F comes out to be = 204.4 degrees Centigrade
