Good Cheap Soldering Iron
 
A friend of mine is putting together a middle-school electronics lab,
and wants to get some good cheap soldering irons. I've been traumatized
by some really pitiful soldering irons so I don't just want to go price
shopping. However, since I've been using professional grade,
temperature controlled irons almost exclusively for years I can't
recommend any good cheap ones.

Can anyone recommend a soldering iron that will actually work but
doesn't cost much? I'm thinking of a rough equivalent to the Weller
WP-25, but that costs less than $20 a pop.

Thanks in advance.

Tim -

The Weller TCP series is routinely available surplus and easy to repair.

I see WTCPL, WTCPN & WTCPS systems selling on eBay for $ 25 or less --
I have seen in last 4 weeks at Chicago area hamfests -- very good WTCPS &
WTCPN stations selling for
$ 20 to $ 25 (some may lack the stand - but that is an easy fix/purchase)

The WTCPT (current production model) will usually get a few more dollars
depending upon condition.

Used bases run around $5, sometimes $ 10 for a cosmetic excellent condition
unit.

Factory and manufacturing closeouts also produce large number of soldering
stations in this price range.

New in this price range - you are left with a variety of 120 VAC stick irons
of various wattages.

Salvage sales? A lot of people at our place took home Weller temp
controlled stations as the labs switched over to Metcal, and I've seen
stacks of Weller irons at salvage places (as companies continue to go
belly-up).

www.circuitspecialists.com has some that look reasonable, although not
under $20 they are temp controlled[*] and have holders. One is about
$30 and the other about $35.

http://www.circuitspecialists.com/prod.itml/icOid/7307

* it says "adjustable output" so may be open-loop control.

I've purchased from them in the past (and also under their other link
www.web-tronics.com) and they seem reputable. YMMV

Circuit Specialists is a good outfit... been around for a long time

About the only place in the Phoenix area to buy **real** parts.

I did not mention the second soldering station that Rich references for 2
reasons,

1.) Its price was outside your $$ limit

2.) This station is obviously an OEM version from same Singapore mfg. that
makes the Haako 936 BUT with a connector change instead of the Amphenol/Tyco
used by Haako and Circuit Specialists name.

I do know that some Haako dealers aware of this unit are upset with this
offering and were planning to talk to their Haako representative.

Lucky you. PDX has a Fry's and a little local outfit, but that doesn't
count for real parts. I used to live in the Boston area, 30 minutes
away from an Active store -- that was nice, particularly since it backed
up against Future (same company) & you could get non-catalog items at

If the Hakko dealers are upset about Circuit Specialists, they really ought to
"love" Madell Technology Corp. (http://www.madelltech.com). They have a QK936A
station that not only looks exactly like a Hakko 936, it appears to use the same
connectors. They also sell several hot air stations that look amazingly similar
to Hakko units.

Tim -

How many do you need? I have probably 4 or 5 original NOS Weller WTCP
stations (no neon, no switch) - that I have here.

One middle school talked to me about them - but I think they are getting a
donation from a local mfg. company

This iron costs $25 and works well for DIP down to TSSOP. Along with a cheap
larger iron for big wires and a heat gun for desoldering, it's all I use.
Plus holds less heat than a big soldering iron, lessening damage if someone
grabs the wrong end.

Here in the UK virtually all the local component outlets have disappeared.
However, there are plenty of mail order suppliers and one can get most items
the next day.

==============================
Indeed ,considering all the States side parts stories , in the UK we are
most fortunate in having a number of small, often '0ne or persons '
companies supplying ( by 'next day' mail ) a large variety of common and
sometimes not so common parts at very reasonable prices.
Because of their limited turnover they are not forced to levy Value Added
Tax (VAT) = purchase tax.

I am a happy customer (only) of the following 2 , but there are many others

I do not believe thet were as upset with this firm, since the rpice discount
was not as deep and supposedly "one-time" OEM deal -- which as everyone sees

will drop the product.

It's rare here to be able to waltz down to someplace local and get real
components, unless you're lucky enough to happen to be by a big store.

And Fry's don't count for parts (although they still have decent test
equipment for sale).

Computer muffin fans (12 vdc) are a cheap alternative (which is what is
inside the Haako 493 with a filter in front)

The Haako 493 and similiar clone units are available for $ 20 to $ 35 used -
I picked up one for a workbench last month - $ 30 with the shipping !

Train these kids in proper workbench habits and shop safety - first. The
lead-free initaitve is real and in the US we will be working with a "mixed
environment" (repair of older equipment with compnents that may not be able
to handle high temperatures (70 to 90 degrees higher depending upon
formulation used) required for lead-free solders.

It's more like 15 to 20 degrees C higher for lead free solder.

I was referencing F, you are quoting C. I think you math is a bit low for C
(63/37 eutectic is 183 degrees C and Tin/Silver and Tin/Copper eutectics are
at 221 and 227.
Here is the solder alloy temperature chart (Kester's) - so everyone can see
the various formulations, as well as pure tin melting point and the
lead-free formulations.

The exposure to fumes by a child will likely be minimal but, as
the purpose will be 'educational', there may be a duty to employ
best practice so they end up knowing what a safe workstation is
like.

Hmm. Depressingly good point. I just hold my breath while soldering
and wash up when I'm done but I really ought to get a hood --
particularly since I'm training my kid to all my bad habits.

========================================
With the room being ventilated, a small axial fan positioned close to the
soldering area will adequately disperse the fumes .

But if you had a whole classroom of N children soldering, then
N dispersals scattered over the N children might result in a
fume density of N * N / N which would be no dispersal at all!

Industrial soldering set-ups have a small vacuum pipe mounted on
the iron close to the tip to draw away fumes.

My first serious soldering was a Knight-Kit at age 14, and I started
working full-time as a TV serviceman at age 16. I'm here to tell you
that the fumes haven't affected my cheese. Watch it, spaceman, you're
crushing my petunias. Nerts. Hot solder pie with crunchy plumbing, yum.
No ill effects whatever.

Lucky you. PDX has a Fry's and a little local outfit, but that doesn't
count for real parts. I used to live in the Boston area, 30 minutes
away from an Active store -- that was nice, particularly since it backed
up against Future (same company) & you could get non-catalog items at
the counter if you really needed them.


When I lived in the Boston area Radio Shack was a real parts warehouse
(on Commonwealth Avenue) with a will-call counter (only 45 years ago
;-)

That was probably before they got bought by Tandy.

When I lived in the Boston area, I would drive by Radio Shack on the way to
Scully Square and the real good parts.
Cheers,
Harry


Scollay Square was a little before my time.

Of historical note, the Sears Crescent Building there, still standing,
was where A G Bell and Watson worked on inventing the telephone.

Greater Boston still has You-Blew-It Electronics in Needham. (Actually
You-Do-It). A few other suppliers, but not like when this was a center
of manufacturing.

Happy trails,
