Weller magnastat soldering iron problem
Intermittant failure to heat.
Not due to failing switch, but original plastic stress-relief sheathing at the blue body gone hard with age and causing stress to cable and then a conductor break. Makes you wonder where all that plasticiser migrates to, presumably us , quite a bit. |

That's your dashboard, vinyl, carpeting, wire insulation, powder coated parts, upholstery, foam, virtually everything in your car's interior except the metal itself, condensing on the glass and every other surface. Good reason to keep the air flowing thru the vehicle as you drive, minimize the inhalation of those compounds. Gotta love that new car smell. |

Weller magnastat soldering iron problem
My assumption has always been household cooking grease. Any hard surface that doesn't purposefully get cleaned regularly in a house where actual cooking takes place seems to accumulate airborne cooking grease. It soaks into soft surfaces, but creates an oily film on everything else.
Used to make a lot of service calls into houses in certain ethnic neighborhoods. Bring TV sets back to the shop... first thing we did was wipe them down with glass cleaner. The ammonia in it worked much better than the "409" type cleaners of the day against cooking grease. Some sets were so greasy there was a real risk of dropping them on the way out of the house. Sometimes the line cords were literally furry with grease and accumulated dust. And the high voltage sections, even worse. You may be referring to something else... that was just my observation.

One tip that certainly avoided the barrel cracking at the hot end, transistor tab mount insulator, one above and one below the flange of the 3 fixing screws, may have helped such long service.

Today, most PVC and rubber cables use phthalates or ortho-phthalates as a plasticizer to soften the plastic and make it flexible. Before about 1930, it was castor oil or vegetable oil. Yech. http://wwwcourses.sens.buffalo.edu/ce435/2001ZGu/Phthalate_Plasticizers/PhthalatePlasticizersReport.htm (Yes, I know the formatting sucks, but the info looks good). There are also non-phthalate plasticizers introduced: https://www.eastman.com/Pages/ProductHome.aspx?product=71072819 The SDS data says it's 98% bis(2-ethylhexyl) terephthalate which makes me wonder why they claim it's non-phthalate. -- Jeff Liebermann 150 Felker St #D http://www.LearnByDestroying.com Santa Cruz CA 95060 http://802.11junk.com Skype: JeffLiebermann AE6KS 831-336-2558 |

Just make sure they are the cellulose sponges, not the plastic ones - the latter melt rather spectacularly and will foul the tip.
Note that the ones with the Scotch Brite surface are good for tip cleaning at the beginning of a session - but use with care and only when very wet as the material also will melt if exposed until dry. Peter Wieck Melrose Park, PA |

Weller magnastat soldering iron problem
One day a few years ago when I was waiting for parts for my last working Weller station and using my road kit soldering iron, I ordered two of these on ebay:
https://www.ebay.com/itm/60W-Pencil-...AOSwcVZbUAz f These have been pretty much all I've been using since. Except for a needle point iron (EC4000) for very fine work or for anti-static considerations, I've retired the Wellers. These cheap irons are 60W heads and adjustable, although turning them all the way up is way too hot. These never break. Never. Not the heaters nor the wire. I don't have to worry about changing the expensive heaters or therm sensors in the Wellers anymore, or have them go cold/hot during a job because the of another intermittent wire break. There are two cons to these. The first is that the tips are not the greatest, but they're good enough and you get 5 included. The second is that the iron is not regulated. This has never been a problem as the unit's ceramic heater gets the heat to the tip quite quickly. I also use a tiny schmear of neverseize at the tip collar where it contacts the barrel. I bought these to keep strictly for emergency backup to the Wellers, but now I use them every day and bought another for my road kit. |

Jeff-1.0 WA6FWi http:foxsmercantile.com I have no answers Jeff, only my personal experience. Maybe I'm just tough on soldering equipment. I've had many Weller heaters and sensors fail over the years as well as breaks in the wires, and was spending more to keep these things running than I was my truck (okay, hyperbole but still..), and I don't think I ever visited a repair shop that didn't have a Weller pencil handle with tape folding the wire back over itself to keep it in contact. The last straw was the handle for the EC4000 that quit after about a year with minimal bench usage. I forgot what I paid for that but it wasn't cheap.. I replaced it again because there are times when I need an exceptionally fine tip but I use it maybe two or three times a year at most to preserve it. Otherwise, it's the cheap Chinese ebay 60W pencils that I've been using every day, most of the day. Not one has crapped out in almost three years, and even if one did, I have another $8 one brand new on the wall still in it's little baggie. I spent less for these than the shipping cost of getting Weller parts to my shop. You know what else I've gone cheap on? Shaving razors. I now buy Trac II generic blades: https://www.amazon.com/Personna-Twin...eywords=tracii If I replaced the blade once per week, I get two years for $15. Since I replace them once every two weeks, I get four years for $15 (that's just $4 per year), and I can't tell much difference between the generics and the Gillette. |

The patent mumbled something about it being safe because the soldering iron is at a lower temperature than the breakdown temperature for melamine (345 °C or 653 °F)[1]. Solder melts at various temperatures depending on composition. Pb63/Sn37 melts at about 188 °C while the unleaded crap melts at about 220 °C. The soldering iron tip run somewhat hotter than this, probably at 250 °C and 280 °C respectively. I'm not sure what my Weller irons are running for a tip temperature, but I'll check. I have a Hakko FG-100 buried somewhere. Anyway, there seems to be a sufficient margin between the tip temperature and where melamine breaks down.

Then you find out how much of your survival stuff requires gasoline, or electricity or manufactured stuff (like ammunition) to work. Yep. It's kinda like Y2K on steroids. I sold quite a few computahs to those panicked by threat of a Y2K computer meltdown which didn't happen. I'm sure various entrepreneurs notices and decided to perpetuate the fears to generate some business. No, I grew up in Los Angeles, all of my stock pile of OEM spare parts was acquired at surplus stores, swapmeets, garage and estate sales And the occasion "Score!" on eBay the Free Cycle mailing lists or Craig's list. Ditto, and in the same city (as you well know). At one time, I was dragging home car loads of junk from the TRW flea market or JJ Glass. Most of that has been recycles as I lacked the time to fix the stuff, and the space to store it as its value depreciated. I also found it less fashionable to be surrounded by electronic boat anchors. My lab is still very much 1970-1980 vintage test equipment, which is well worth keeping. But, if I buy any replacements, it will be something much newer. Incidentally, when I buy something on eBay, if I want to work, I buy three.

Is there some special ordering code for defective Weller equipment? My first Weller was the soldering gun in 1968. Still have it, it still works. Shortly after getting hired at TRW in 1973, I was introduced to the TCP magnastat series. I've owned and used them up until 2001 when I bought the WES51 style. I have a pair of the DS600 desoldering stations. In all this time, other than tips, I've had to replace the cord on a TCP twice (two different units) and a heating element once. I haven't had any problems with the desoldering stations, nor have I had any problems with the WES stations that are now 17 years old. -- "I am a river to my people." Jeff-1.0 WA6FWi http:foxsmercantile.com I have no answers Jeff, only my personal experience. Maybe I'm just tough on soldering equipment. I've had many Weller heaters and sensors fail over the years as well as breaks in the wires, and was spending more to keep these things running than I was my truck (okay, hyperbole but still..), and I don't think I ever visited a repair shop that didn't have a Weller pencil handle with tape folding the wire back over itself to keep it in contact. The last straw was the handle for the EC4000 that quit after about a year with minimal bench usage. I forgot what I paid for that but it wasn't cheap. I replaced it again because there are times when I need an exceptionally fine tip but I use it maybe two or three times a year at most to preserve it. Otherwise, it's the cheap Chinese ebay 60W pencils that I've been using every day, most of the day. Not one has crapped out in almost three years, and even if one did, I have another $8 one brand new on the wall still in it's little baggie. I spent less for these than the shipping cost of getting Weller parts to my shop. You know what else I've gone cheap on? Shaving razors. I now buy Trac II generic blades: https://www.amazon.com/Personna-Twin...eywords=tracii If I replaced the blade once per week, I get two years for $15. Since I replace them once every two weeks, I get four years for $15 (that's just $4 per year), and I can't tell much difference between the generics and the Gillette. I have experienced all the failures mentioned with Weller pencils and soldering stations. Except for points, I've had zero failures with Tenma soldering stations. |

Do you happen to know what the oily or slimy stuff is, that coats old very flexible cables such as telephone movable extension cables, a bio-film or plasticiser like chemical ? Some old vinyl cables ooze as they get stiff, so that's a plasticizer. With any luck, it's an obsolete plasticizer. Unless the cord is special, destroy it. Occasionally, though, the outer sheath is bad, but the inner wires are rubber-insulated (I try to keep those, they're limp and make good test lead material). Real rubber-insulated wire is just barely still available. |
