Question about Weller Welding Tools

1 Answer

I mistakenly left my spg 80L plugged in over night. I now find it difficult to melt the solder I've been using and switched to one with a lower melting point. Did I damage the iron by leaving it plugged in so long? About 10 hours.

What probably happened is that the tip oxidized (typically made of copper) and the oxidation layer is a very poor conductor. You should be able to go on Google or Amazon and find a new tip for your iron. They cost about $5 and it should be good as new.

I would also recommend tinning your tip everytime you are done soldering. All you have to do is put enough solder on the tip to cover it (usually only about 1/2") and then turn off the iron and let the solder dry. This will help prolong the life of the new tip.

Samsung b1445a door interlock burnt out

Even if it is soldered on, if you feel confident you can desolder it off with a soldering gun! Then you could go to a good hardware store and get the size spade lug you need and solder the new one on!

Casio PRG-80L reads open

Have the same problem, Casio PRG-80L reads open. No hints about this in the manual. Nor did Votit's suggestion help. Note that although the watch is old there is clearly power left in the capacitor battery. Ended up accidently ito this mode when resetting the time. Assume the open mode is intended for service, but would just like to exit.

I have nad tuner 4155,sounds garbled and very little volume

Hi, you might need to replace Some damaged resistor controlling the sound function.
Please if no basic experience ,contact a repairman.

Replacing Damaged Resistors

Disconnect the stereo at the plug and remove the outer case.

Confirm that the resistor is damaged by testing the tolerance with a multimeter. Melt the current solder with an iron and remove the damaged resistor.

Mount the replacement resistor onto the circuit board. Trim any surplus lead material from around it.

"Tin" the tip of the soldering iron by melting a tiny amount of solder directly onto it. Remove any surplus solder and place the tip straight onto the circuit board.

Melt a tiny amount of solder straight onto the joint, using the solder spool. Ensure that the solder does not touch the tip of the iron.

Melt the solder straight onto the area between the resistor lead and the printed circuit board. Leave it to set and ensure that the joint is strong. Reassemble the stereo and test it.

Also Spray the volume control knob with electrical contact cleaner. Twist the knob from low to high to make certain that all the workings are adequately lubricated. This should eliminate any interference that you've experienced when adjusting the volume.

Check the condition of the speaker wires if the stereo is emitting no sound. Ensure that no bare wires are coming in contact with each other. This will result in a dead short. Replace any damaged wires with new ones.

Check the connections of all speaker wires if no damage is detected. Ensure that the wires are securely connected at the back of the stereo and at the speakers' connections. Confirm that the positive and negative connections on the stereo are connected to the corresponding speaker connections.

Good luck..

Does not melt solder

The body contains a transformer, which steps your 120AC down to a lower voltage. The lower voltage runs THROUGH the tip, heating it up. Possibility ONE: Transformer is no good, throw it away. TWO: Not enough current is running through tip, because tip is corroded OR those mounting nuts are corroded, loose, OR somebody put new tip into nuts but neglected to bend both legs of new tip 90 degrees. Look at the barrels, you will see little holes in the sides, tip's legs go into those holes.

No left channel when cold

Hi this sounds typical of a "cold solder joint" in the solder around a component in the area concerned with that channel.
These are very difficult to spot.

If you want to repair yourself - buy one of these -
Lighted Microscope 60 - 100x

And read this -
Spotting a cold solder joint

Once found, the solder should be melted with a soldering iron, while a little flux is applied.
