I was trying to replace some components in a radio, but as soon as it gets hot enough to melt solder it starts melting the circuit board. I'm not sure what I'm doing wrong. Maybe I'm using too much flux?

Soldering trouble

Maybe this guy needed that iron. Looks like the one he used required 'sculpting' the solder instead of melting it.
This is where he attached the hot side of the "ping" capacitor.
The rest of the radio has more of these. Just hope we don't miss any of them. When someone tells you the radio's capacitors have "all been changed", it pays to have a look-see first.

Looks like he used solder for plumbing instead of solder for electronics. Or the wrong kind of flux.

Or, almost enough heat, but for long enough to burn away all of the flux?
At least I didn't smell any zinc chloride when the iron touched it.

Stained glass?
The lead they use has a higher melting temperature than tin/lead solder.
Takes heat to melt the formed lead channel onto the glass edge, too.
Or making a copper whiskey still with lead-free solder?

I watched a show where they used old school heated irons like that to do copper roofing. Was cool to watch.
I've seen these used for roofing as well, also for fancy copper gutters and such. Mostly for restorations on historic buildings.
It is used for copper and other sheet metal work. Need lots of heat for sheet metal work, it conducts heat away from the joint you are trying make.

My grand mother once told me that when my grandfather was building the house they didn't have big electric irons like that. The irons they used for the copper gutters and downspouts had to be heated in a fire pit in the yard and the guy tending the fire would toss a hot one up to the guy on the roof when needed. I would love to have seen that.
If all fails that would be a great piece to put under the seat of you Car/Truck , Police stop you .... Hey I'm an outdated plumber ! That thing would hurt !
That would make an interesting Stabbing Weapon. Wound them and cauterize in one step.
