20 Most Recent Weller 8200 Soldering Gun Questions & Answers

I am assuming that you installed a new tip. Note, the tip ends have to be 3/8 of an inch 90 degree bend so that when you insert the tip leads into the barrels, they go into the small holes in the barrels. Also note, the nuts to tighten the tip into the gun have to be installed onto the tip leads before bending the leads. Now when the tip is installed this way, the nuts tighten and hold the tip in the barrel. This tightening of the nuts allow the tip to have a good electrical connection to the barrels and this is what allows the tip to heat. You actually have an electrical current that passes through the barrels and the tip. It is a very low voltage (around 2) but a very high current. Over time the tip will not heat, this is a sign to either tighten the nuts, or look at the tip to see if it has a break in it. If it has an open, then it is time to change the tip.

There are normally three of the same type. They are consumable, you don't need to stock all the different types - just buy the one you need for your current project.

Note, these are high power and were commonly used for soldering wires in the point-to-point wiring used in old tube electronics. Do not use this on a Printed circuit board - it will damage any silicon component.

Use a a soldering pencil for printed circuit boards.
