This soldering station is more suited for electrical work. For wrought Iron I would think welding or gorilla glue would be better.
It can be used at the high setting with the largest flat tip installed for a large contact area. Use a fan for fumes.
Various so there is no clicks that set it so variable settings!
It comes with one tip, but additional tips are available. They tips can be easily replaced or changed
I soldered cb parts I would recommend getting a finer tip they have available for it
Mine only came with the one tip but the box was opened and they only had one. Maybe someone else bought this and can chime in.
If I was I would look up the melting point of silver solder and then compare it to the solder gun go from there
Yes, a few tips are available that will do the job.
