Weller solder iron tips
« on: June 07, 2018, 04:38:39 PM »
I lately bought a Weller solder iron tip from Communica, nicely marked "WELLER", but unable of being solder-coated. I can only assume that the "coatable" layer on the tip was too thin; it assumed a black (oxide?) colour almost immediately and that was that.

So the expected question: Where to get and more important, how does one know if it is the real thing? I find in fact that none of my older defunct tips had 'WELLER' engraved on them! So rather than buy one of the newer thingys (R !!!), any advice for this old hound apart from laboureously importing, please?

Similar thing happened with the bits I recently bought from Mantech. Got me suspicious that my thermostat was not working, though I can hear it clicking away (it is the old Magnastat type).

If ur in Durban, then A1 Radio has a good range of tips and know someone who bought a generic branded tip for a Magnum2000 and still going strong. Possibly a reliable supplier even if is not the OEM branded part.

RS Online carries most Weller tips. That is where I buy my station's tips.

I baught a "narrow" tip from them and works perfectly. 6 or so months later and used at least half an hour a day on average.

The tip of our workshop Weller was also nice and black - from the typical abuse it receives in a lawnmower shop.

Removed the tip, lightly wire-brushed it, shaped a new point with a file.
Replaced it in the iron, heated it up and re-tinned it with solder and it's as good as new.

The tip material appears to be pure copper.

Tom, that tip is kaput. It should have a plating of nickel over the copper. You can still use it, but it will corrode due to interaction with the flux. The nickel or iron plating resists this corrosion.

Thanks Shaun.

Now, where do we get replacement tips?

Thank ye all kindly, Gentlemans.

In the meantime I have found that Mantech sells a brand: 'Plato' Weller tips, manufactured in a fairly large tool business near Atlanta, USA. Also, that RS stocks Weller tips, unknown manufacturer.

and also that a fairly large Chinese factory makes them!!  :(  :(  :(

For those interested: It would seem (from my limited experience - limited brandwise, not usewise; we used many in the CSIR) that the original Weller tips have the metal back side visibly crimped onto the main body with a 3-jaw crimping tool, where the doubtful types have the metal sensor smoothly pressed into the tip body.

Further, all my genuine Weller tips have the word WELLER clearly stamped on the body of the tip in letters some 2,4mm high. Often (but not always) the type of tip is clearly stamped on the opposite side. Doubtful ones have the name lightly stamped on in smaller letters.

I am not fortunate in locating things on the RS site but will try looking (they are quite closer to me at Kayalami than Mantech in the south of Jo'burg) or phoning.

Then I still have my 34 cm. long 60W Solon soldering iron of >60 years vintage with a 8 mm round copper tip, making light work of fairly hefty jobs!  ;D  ;D.  How to do printed circuit jobs? A coil of 1mm copper wire wound round the tip and ending in a fine sharp point is just dandy! (Er- well; one has to file down the oxide layer occasionally, but never mind. A man needs a break now and then ....)

Thanks again. Contributions by others with experience, positive or negative, will perhaps be appreciated by all.

P.S.: Forgot to mention that I use 60/40 solder all the time; not the new-fangled formulas.

Christensen is not exactly the best in terms of service.. alternatives are Techcraft in Cape Town, otherwise I've found RS to not be overly expensive.
Personally for my work I get all my Weller stuff either from eBay (new) or Digikey.

Not strictly true, they are a sub-distributor, like the others mentioned.

In KZN your best bet is AAW Electronics.  The locally produced Magnum range of irons uses Plato tips.  Wellers are different.

Slightly off-topic, but once you go TS-100, you never go back! Honestly, I was a skeptic before I got one of these puppies. Insanely powerful, a joy to use. Haven't bothered with old-school Magnum/Weller irons for hobby work ever since.

You can make your own solder tips or restore old tips if u have the time. Old copper tips: turn them in a drill , some fine sandpaper, then polish them with a piece of soft pine wood. Make the tip as smooth and shiny as possible this way, removing any oxide and surface scratches etc. Prior activity could be sharpening the tip if the point is not fine enough for your work.

Then, electroplate the tip with nickel. Can do this at home, nothing special is needed, (search www for this). I dont know how thick the coating should be, but 2hours plating time could be ok.

Then, electroplate the tip with phosphor bronze. Apparently  this is one of the best metals for use as plating on a solder tip. A great source of it is old guitar strings. (Lucky I kept my old strings) . 

I guess its not easy to get copper stock rod in the exact diameter for your iron, but other metals could work well, iron steel maybe bronze as well could be ok, but must nickel plate first, then phosphor bronze plate.

I will be trying this soon, reviving a "new" suddenly blackened tip on a magnum station. In fact, I got the wrong tip (for a weller and modified the back end of it to fit)  I guess the tip is not genuine, but want to see if I can make a good tip and see how long it lasts. If it works, then saving R80 a shot for minimal cost and time of initial setup is worth it.
