You should be able to find actual temperature information somewhere, but I usually just eyeball it and then reach for a pencil of the appropriate wattage. In general, you want the solder to melt completely within a few seconds after you touch your pencil to the joint. That will depend on the size of the joint and the power of the pencil. That's why I eyeball it and for a little surface mount kind of joint I would reach for a 15 watt iron (try your lowest temp setting) and for a big joint like on a flyback transformer I would go for the 45 watt or even 100 watt iron. If you can't find any good information I would start at the lowest setting and see how that works. If the pencil is well regulated (maintains constant temp) it will increase the power to the tip to maintain a constant temperature, and so as long as you have it set higher than the melting point of the solder it should melt the solder quickly. Most electronic components will tolerate about 200C for at least 5 - 15 seconds without any hardship. Jeff Walther -- SuperMacs is sponsored by <http://lowendmac.com/> and...
