20 Most Recent Weller 8200 Soldering Gun - Page 2 Questions & Answers

Yes actually, you need a special paste to do so try to google Aluminum Soldering Paste. I would think though in terms of strength its not going to be that strong nor reliable. Also aluminum is best not to solder unless you have a proper MIG welder. If its a flat surface try rivets.

You might try getting new bolts that are the next size up. For example #6 x 32 to # 8 x 32. Just tap out the existing holes.

No! it is for electronic circuitry that it is designed for.

Hello, does your soldering gun humm? If it humms then recycle the parts. There is short across the winding which causing the humm. If not, then make the you have right soldering tip for your Weller gun. Also make sure there is good tight connect on the solder tips with the barrel screws.
It could be a faulty two way trigger switch with internal diac controller. You can order switches from this web site: www.e-sonic.com/aboutus/cat/S/soldering%206.pdf GB...stewbison

When I dropped my 35 year 0ld 8200N, I cracked a large piece out of the case above the grip. I used a steel filled epoxy called JB Weld to join the pieces. It is a two part epoxy that cures in 24 hours. Make a mold using masking tape to fill in missing pieces. The epoxy is runny at first, it will thicken in about 6 hours. This compound will fix about any thing and can be drilled and tapped like plastic. It will even adhere to the 8200N case material. The usual clear epoxies won't hold up.

This sounds like a "contact" problem where the tip installs in the gun. I would remove the tip and burnish the connections with some very very light sand paper or steel wool (an emery board is a nice 'tool' to add to your tool box). You'll also need to clean the gun connections themselves. Also make sure the connectors are tight, but be careful not to overtighten them or you'll break them. Good connections = good heat transfer. Good Luck.

Make sure the copper tip is intact and that the tip nuts have been loosened, then re-tightened to make clean contact of the tip to the gun barrels. The lamp is tied directly across the barrels, and when the tip is open circuited, the output voltage goes up enough to burn out the lamp. Hope this helps!

The voltage is nearly unreadable it is so low, but the current is quite high. If the tip won't heat, loosen the tip nuts and re-tighten.
