How to unsolder for your repairs

ISO-Tip

There’s a lot in our name. For more than 40 years we’ve been building the 7000 series portable soldering irons and the pro’s tell us they stand apart from the rest.

Our Isolated Tip design gives high temps fast at the push of a button, up to 900°F in less than 10 seconds! You might find yourself done with the job while other irons are still heating up. By isolating the tip we prevent electrical leakage that may cause component damage while soldering. Most portable soldering irons offer only a few tip choices, so over the years we have developed more than 20 tips to meet your soldering needs. Our High Efficiency tips give you a quicker heat-up time and use less battery life. The Long Life tips are nickel plated and designed for more continual use and will meet the needs of your tougher tasks. Our long list of standard tips will work well for your general soldering needs. For over 40 years, professionals have looked to us for advancements in portable soldering and we have enjoyed meeting that challenge.

If you’ve never tried one of our cordless soldering irons we hope you will. We also supply other “tools worth discovering” for heating, finish work and the tough soldering jobs. If you have a need let us know, we do appreciate input from the people that use our products. Not all cordless soldering irons and especially tips are the same. Let us know what you think, we enjoy what we do and appreciate the people we do it for.

TESTIMONIALS

This soldering iron is worth every penny [Model #8000].

It comes to soldering temperature quickly.

Since it shuts off after each joint the tips remain intact

I absolutely love this iron and expect it to last for many years.

I’ve heard many great things about these irons [Model #7700] and their lifespan, so I decided to buy this to help in my search for a portable soldering iron…My favorite feature is the fact that it is heat-on-demand, with 45 watts in such a small tip, temperature control is easy and it heats up super fast. 

It works exactly as I remember, great for small parts soldering.

I had one of these (mine was red with an led on the front) over 30 years ago. The battery went dead and I didn’t know how to get it replaced so I threw it out. Always wanted another one and finally found this one [Model #7700]. It works exactly as I remember, great for small parts soldering. I am surprised the design was not updated to use lithium ion batteries. But then they would increase the cost.

Which cordless tips can be used with which iron?

All of our cordless tips are interchangeable with our 7000 and 8000 Series Soldering Irons. Here’s our complete catalog.

How to install a new battery?

Open up the iron. Unscrew the contact plate connecting the tip of the iron to the bulb. Take the plate and tip out of the iron. Remove the screw near the top of the battery that attaches the battery to the orange wire. Remove the screw near the bottom of the battery. Carefully remove the battery from the case. Replace necessary parts. Reassemble by following these steps in reverse order.

How to rebuild your 7700

What voltage output does my transformer have?

Your transformer should have an output of 1.7 volts.

What's the max. wire gauge I can solder?

We recommend that you use size 16 AWG or smaller for our 7000 and 8000 series. For more information on this subject click here.

Soldering iron doesn’t seem to hold a charge after being on the charger for 3+ hours.

Check a couple of things…

  1. Take the tip out, press the button. If the light comes on, the battery is charged. Try a new tip.
  2. If the light doesn’t come on, open up the iron. There is a small fuse wire that should be connected to the bottom lead legs and the battery. Is this connected? If not, reconnect. They can come loose during transit.
  3. If the fuse wire is connected, what is the output of the transformer? It should be ~1.7 volts.
  4. If the transformer is outputting enough voltage, new battery or rebuild is likely required.
My light comes on, but tip won’t heat up.

Try a different tip. The one being used could be causing a short.

I have an older ISO-TIP soldering iron, what battery can I purchase to repair, or can you rebuild?

If the iron is orange, gray or the 7500 S.I. model, our 7733 battery will replace or send in for a complete rebuild. If yellow (7800) or black (7904), we can no longer offer replacement parts, but you can upgrade to our current models for a discount. Or visit your local Batteries Plus for replacement batteries.
