Well, small car/motorcycle/ups battery, powerful enough DC/AC inventer and you good to go.
That's what I would normally use, but a lot of inverters say that you aren't supposed to use them for large resistive loads, so it would probably be best if she is using something that is built for that kind of load.

My father had solder iron with a transformer primarily as galvanic isolation. I never knew it's ratio. (I believe he said once it lowers voltage) Also, knowing that electrical heat is more dependent on current than voltage, the transrormer may have proper ratio for more current with same power output (but that isn't necessary).
So adding transformer between inventer and solder iron can decrease "resistive" factor on load.
Why would you need to use inverter for just a simple resistive soldering iron? You can just hook it up to a battery directly and it'll work fine. Just scale the wattage properly (i.e. a 110V/80W soldering iron will work like a 35W soldering iron when connected to 48V car battery). Frequently use this when I need to do field repair and need to work a somewhat ESD-sensitive components (for some reason, most of the home installation here doesn't bother creating local ground, or just connect ground to neutral wire. Hey, it saves one wire!)
And, no, adding transformer wouldn't reduce the "resistive" load factor. It does somewhat smooth out the usually janky output of the cheaper simpler inverter.
