Sure wish I had Read the Fine Manual when I was 20 something for my Weller 8200
soldering gun. I've been using it wrong for the last 40 years. I thought that the
first detent on the trigger was 100 watts and the second detent for 140 watts.
So after waiting plenty long enough for solder joint below to melt, I determined
immediately that I needed a BIGGER soldering gun.
So I bought the Weller D650PK. Being older and wiser now I read the manual
and noticed that the highest heat came first, but it still didn't hit me right
away. It took a couple of days before the light came on and I began to wonder.
So I looked up the manual and low-and-behold, my old model 8200 was the
same way......damn!!!
Oh well I got another tool, and I like to think I really needed it anyway for some
of the bigger things I MIGHT need to solder in the future.
