soldering iron

Hi Sue,
I just got another Weller 100 and the store I bought it from suggested I use the temp controller with it. I was reading through some of the other questions about which iron to use and you said not to use a temp controller. Now I'm confused. Maybe they wanted me to use a temp controller because my other Weller blew up in my hand.......that was a shock.

Answer

If your iron is the W100PG (the 100watt iron with a light blue handle), it cycles on and off automatically to maintain a constant temperature. This feature eliminates the necessity of using a separate temperature controller. If you take out the tip you will see a number on the flat end. 6 gives you 600 degrees, 7...700 degrees and 8...800 degrees. The iron comes with the 700 degree tip.

Here is just one of many places that sell Weller irons and states that the W100PG does not need a temp controller: Weller Info
