Lots of discussions but as always no definitive answers so i'd just say......get a weller 120 watt electric iron for home use and maplin have a 70 watt gas one on offer at
Searching isn't quite that easy when your new to forums and plus the fact if everybody did a search and got the answer then there would be no interaction and we'd all just die of boredom....i've been searching for a definitive answer on diff oils for a hyper 7 E for a while and still none the wiser!
