Hello, if the head element in the barrel of this soldering iron is shot. Recycle it and save the copper and other materials for recycling. Recyclers are pay $3.20/lb for copper, $1.86/lb for brass.
Remove the three screw on the front plate and pull the cord. It's apart. GB...stewbison

Just loosen the screw in the barrel near the tip, then rotate while pulling the tip out. It shouldn't be necessary to remove the tip unless it requires replacement. Hope this helps!

Chances are that the screw and maybe the hole in the iron barrel have been 'cross threaded'. Remove the screw and the tip, then examine the screw and hole threads for thread damage. If they are, the screw should be replaced, but the hole in the barrel will need to be cleaned with the proper size tap. You can find the tap and the screw at a home center, or hardware store , plus get some suggestions on how to fix your problem. Hope this helps!

The most likely problem ishte heater inside the pencil. This can be replaced for around $25. Check with a local electronics supplier for the replacement parts. They are readily available on teh web too. I believe that MCM Electronics. Digikey and Mouser all have these parts available.

There is a bimetalic strip and a magnet that can get stuck in the closed position. Tapping the iron on the end of the bit can release it otherwise a new element will be required.

Hi, I'm not sure the tip is defective. Check that the tip is screwed in tight. If it is not good and tight the tip will not get a good heat transfer from the solder wand. Hope this helps. If the wand will heat then the tip should.

Sounds like main transformer is bad or bad connection. Unplug it and take it apart and check for loose connections. Good luck.

If element still heats up then only the bulb needs to be replaced. "https://www.6ya.com/philip_b05beb373d913f26"

I am looking at my Weller Portasol P-1k unit right now. They use standard flints. Go to almost ANY store you can think of and they sell lighter fluid and flints (usually sold in a pack of 5). About a buck or two.

nice to know what is wrong with it

Yes, 9 times out of 10 its' the thermal coupler.

If this is the dual trigger Weller gun and your tips are held in place by either set screws or by locking nuts, Just loosen both of the parts that are holding the tip to the gun and then retighten them back up. Soldering iron tips that appear to be tight might not be and this will insure that the tip is indeed tight and also cleans up the connection of the tip to the soldering iron. Oxidation from heating and cooling will cause a tip to not get very hot. Loosen the tip holder and then retighten it. Hope this gets you going again. Dennis

Unless you are only interested in soldering tin/lead joints... I sincerely believe that answer to be "No"... What kind of metals were you planning on working with would be a GREAT PLACE to start... and the figure out the temperatures you will need to achieve.. A word of extreme CAUTION. Working surfaces have to be able to withstand EXTREME TEMPERATURES. Cement will come apart with explosive force... and getting any water onto molten metal can also have catastrophic consequences... so a little supervised experience would be well advised place to begin...
