why is that?

What do you mean exactly with "irons", "shaft" and how exactly do you sold them?This is a link to a nice picture of a soldering iron:http://microtorches.ayay.com/Soldering%20Iron%20solder.jpgwithout meaning to sound rude, the shaft would be the...ermm..the tip is at the end of the shaft. Imagine a pencil, the bit you hold is the shaft and the part you write with is the tip. Hope that explains it well enough.
English is a barmy language, isn't it?(What's 'barmy' in Italian?)
Some soldering irons manage to get the tip hotter than the shaft because the shaft may be a bit insulated or even made of shiny stainless steel. The main reason that the tip will melt the solder easier is because it is either copper or it is plated with a metal that amalgamates easily with the solder and 'wets' easily (the solder in contact, initially, melts) and then there is a good thermal contact which aids more heat flow just where you want it.The shaft soon gets oxidised and will just not show any interest in the solder at all. It can still burn your hand badly!The word 'welder' would usually be reserved for an instrument using aflame or electric arc to melt the metals to be joined. Soldering would normally involve a low melting point alloy which sticks to each side and then solidifies. Brazing is a form of high temperature soldering. Soldering / brazing will produce not as strong a joint as welding, usually.English is a barmy language, isn't it?(What's 'barmy' in Italian?)
Why do soldering irons go hotter at the tip, than the shaft?why is that?

Barm, in English, is a word for the frothy surface of a liquid (beer)which is fermenting. But, colloquially, barmy means daft, dumb, mentally unbalanced - the result of consuming alcohol, perhaps. I think your third meaning was nearer what I was getting at, Lightarrow.English constantly mixes it Nouns and Verbs- , using gerunds a lot. So a walking stick does not walk - "I saw a man eating fish in a restaurant" does not mean there was a shark in there.btw, where does your name 'lightarrow' come from - or is this too personal information?Sophiecentaur refers to my aged Yacht - a Westerly Centaur, name of Sophie.CheersAndrew
You're not doing badly as an arrow of educational light!You have put a lot of people straight on several occasions.I do have a profile - that tells people my gender.Funny but you are not the first person on this forum with a Scientific mind to have made the same assumption.
