Obviously you have to set your iron tip temperature slightly higher in order to use this material - 185-200 Deg. C is about right. Kit manufacturers tend to use different Whitemetal alloys, so you must test first. Our own experience is that setting your tip temperature at 200 Deg. C is OK for DJH kits, but would need to be used with extreme caution on ABS kits and others manufacturers' Whitemetal parts that are cast for them by Adrian. So we say again, please test before using.
