What's the topic of this post again?
"Recommendations for Soldering iron" I believe, asked by Chessie....though I am not sure that I have ever seen a soldering iron!
That probably goes back to olden days when one might have been made from iron, instead of copper. Today, you would be hard pressed to actually buy one....though almost every web search will show/sell/provide sellers of such an item. Even most of today's tools, use a copper filament as the heat transfer source...witness the statements about replacement tips.
I guess any item that can provide enough heat to melt the combinations of alloys that we call solder, can be called an iron today. I would not try to press pants or shirts with such an "iron." And, as the other John wrote, sal ammoniac is another sign of changing times! It is rarely seen, and probably not used by many on this forum...if many have EVER used it.
I am guessing that many new users to the act of soldering, assume that all solder is alike, and may need some information on the differences in them. But that is another topic, though new users should be advised not to grab dad's or granddad's roll of just any cored, fluxed solder and use it on their expensive electronic items! If they grab a roll of acid cored, vs. a roll of rosin cored, unless they wash/clean off the residue after soldering, they will be in for a shock sometime in the future.
Likewise with rolls of solder. While the lead and tin alloy works well, it can also work like "black magic" when the % of each is altered. A mix of 60/40% tin/lead, with have different melting temperature and flow rate that a mix of 40/60% tin/lead. While both work, it is good to know when to use each. But, again, a topic for another thread.
And, a recommendation against one type of heat source to solder, can often, be just as valuable as one for a type of heat source....or at least I am thinking so. Like so many topics on this forum, I always seem to inadvertently learn as much, or more, from reading them - than I ever thought I would when I began one of them! I hope Chessie has benefited from the discourse here in these replies from all who sought fit to write, I hope he gets what he needs to know from replies.
Now, if someone would just start a topic about the proper procedure for soldering, we might not see a reply like I saw on an amplifier repair thread the other day....."Well, I botched the solder job. Did not get the joint hot enough, but the tip was melting the solder plenty good...I guess the tip was too big. Ruined the board and some traces, and had to through it away. Guess I need some lessons in soldering" - this from a newbie on that forum.
I am sure something like that would NOT happen to anyone on this forum!? GRJ....want to start that topic?
