If it is a gun it probably will not work as well as an iron of the same or close wattage. Irons should be fairly close to 100% efficiency (being resistance based), whereas those transformer based guns will loose energy in the field and connections to the tip, and also lack thermal mass in the tip. I've gotten good joints on some pretty beefy steel with mine, and I think if he tinned both surfaces individually with an iron like mine he would probably be able to make a solid joint.
