Here are some notes about soldering temperatures. I'm not sure how authoritative these numbers are. For notes about sources see this and this. For info about my actual soldering station see Horusdy Soldering Station.

Tip temperature

You don't want to exceed the maximum tip temperature or your tip will melt and be destroyed. I usually just leave my tip temperature set at 250°C (482°F).

I was in a video from Bruce of Branchus Creations where he said he sets his soldering iron to 400°C, but I've melted tips at those temperatures.

Maximum safe tip temperature is ~380°C (~707°F), not sure where I got that number.

Recommended tip temperature is ~300°C (~572°F), or maybe 340°C?

Heat gun

Over on How To Remove Electronic Components - PART 1 / Soldering Tutorial Mr SolderFix sets his heat gun at 380°C for removing ICs from circuit boards.

Melting points

Solder Material SI Code Proportions Melting Point
Tin-lead SnPb 60/40 183-190°C
Tin-lead SnPb 63/37 183°C
Tin-silver-copper SnAgCu 96.5/3/0.5 217-220°C
Tin-copper SnCu 99.3/0.7 227°C
Tin-silver SnAg 96.5/3.5 221°C
