Plenty of 100W soldering irons for not much money, but 120W gets a tad
expensive.

A true 100w should manage it, but don't expect one of those instant
trigger type 100w irons to cope. Like a gun, with a trigger and and a
copper loop type element.

Whether soldering might be enough, is a different story. I suspect
originally it will have been spot welded. You might be better looking up
how to try that, with a 12v car battery.

If it is plastic, you will have problems with that melting. I thought
these things were sometimes some sort of shell.

Given that the repair shouldn't be particularly visible, I'd be inclined
to use a blob of epoxy.
