Model #7800 Cordless Soldering Iron FAQsModel #7800 Cordless Soldering Iron

Over at Iso-Tip we commonly hear the complaint that the Model #7800 cordless soldering iron gets hot! But, what’s hot?

If you’re the owner of the Model #7800 Cordless Soldering Iron, you may have noticed a snap disc thermostat assembly on the battery pack. When the user presses the white lever, they are sending the soldering iron into the fast charge mode, causing the battery to heat. The snap disc then senses the temperature changes and “snaps” at 125°F ±8°F. Once cooled down to 105°F the snap disc automatically resets, returning the battery to normal state. Also note, if the red LED light never comes on, it’s like the snap disc plunger is stuck.

So what is hot? Well, being the snap disc isn’t triggered until 125°F, if you place a temperature probe on the outside of the soldering iron you’re more than likely to find it to read out 105°F. But if you are seeing above 135°F, then we may have a problem. We recommend sending the soldering iron in for our rebuild program. This way we can test your battery, transformer and other components. The rebuild only has a fee of $29.95 +shipping. To sign up for the rebuild program, call our customer service department at 715-318-2822. Customer service will take your information, ask you a few simple questions about what’s wrong with the tool, and viola, send your iron back to us!
