Question about Weller 8200 Soldering Gun

2 Answers


My Weller 8200 soldering gun is over 30 years old. Lately, the tips erode, then burn through is a very short time. I tin the tips regularly. The gun's case has been broken & repaired several times & I have resoldered the connections of the windings to the switch several times. I am using Radio Shack tips because they are low cost-$3 for 2 tips vs. $7 at for 1 at a hardware store. Should I continue to keep this old gun or is there a fix?

    I have the problem (after buying a new model 8200soldering gun). I switched from no-lead rosin-core plumbingsolder to 40/60 tin/lead rosin core solder. No more eroded tips! And the solder is a lot easier to work with. I also began making my own tips from # 10 copper wire. I hammer it to a square crosssection & cut it ot length. The hammering hardens the copper; After bending to shape, I file a flat on the tip for better contact. works great.

    Sorry, I meant to say "I have the SOLUTION".

    Switch to 40%tin/60% lead, rosin-core electrical solder. easier to work with & tips won't burn out.

It's better to get a soldering station instead.

Do NOT attempt to tap out or enlarge the threads. Weller uses special nuts, you can buy a new tip WITH replacement nuts. If you buy the new tip without nuts, you are supposed to bend the two ends 90 degrees, so they fit into the holes in the two cylinders. The tips which are iron-plated will last longer.

Wont heat enough to solder

Hello, does your solder iron --Weller- humming? Also, is the solder tips the right tips for you Weller woldering gun? Are the tips tightened on the end of the solder gun prongs?

Well, if it is humming there is internal short in the windings inside of the gun. Don't mess with. Recyle it by taking the copper, brass, aluminum, and other metal out. Now, if it is not humming.
Make sure you have right tips, make sure that the tip is tightened in the soldering gun prongs.

The working principal of these soldering guns is that they work on low voltage and very high current. The current is regulated to keep the tip from burning into. Just enough current to heat the tipe to a certain temperature.. It can shock you but there not enough voltage with current but it will hurt. and could burn you. Be careful and lots of luck...GB...stewbison

Weller 8200 series soldering gun sometimes fails to heat; tightening screws and/or gently spreading arms often helps. Is there a permanent fix?

There is constant maintenance needed to keep soldering, the key ones are the tip fastening nuts, and the tip itself. The tip eventually needs sanding and immediate retinning, Clean with damp rag during and after each soldering event, and heavily re tin at end of event.
