hello all
this is my WEP 853D three-in-one solder station.
[It's very dusty because I had it outside in the shed for a few years]
it's got a 60 watt soldering iron and a heat gun, both are capable of 480 degrees
it also has a quite useful bench top power supply
as you can see this one's quite old, the soldering iron has been broken for a while now
i just put up with it
the heat gun also has a fault
early on the fan speed decreased significantly
later i accidentally damaged the power supply
in this video i'm going to fix one problem attempt to fix another
and i'll explain why i'm not going to fix the third problem
first up the easiest thing to fix a replacement soldering iron
according to the eBay page you need to make sure it's the correct iron for your solder station
here it is, we'll just open it up and have a quick look
it's got a spring, the last one didn't have that
the plastic part seems a bit stronger as well
hopefully it lasts longer than its predecessor
let's turn it on and see if it works
it looks alright to me
now for the power supply
i did try diagnosing the problem
it was just a mess so i gave up on that idea
this is only part of it it shares a front panel with the soldering iron in the hot air gun
lately i've been using this DPS 3005 which i reviewed in a previous video. Check the link in the description.
i hard wired a dc socket and some alligator clips on it
later i'll make a video where i put it in a box and make it a bit nicer to use
but even as it is it's quite portable and very handy for getting in shot on various videos
now for the hot air gun, at first it worked very well
then one day the fan speed adjustment didn't seem to do much at all
just check the voltage
it's 26.6 volts maximum
the fan i got is 24 volts, let's see if we can get this replacement to fit
i had to take the ears off with a grinder
now we'll solder it in
now time to reassemble
there's no improvement on the airflow
i'm opening up the airway let a bit more air through hopefully that helps
a slight improvement, the cause of the problem is elsewhere. maybe the speed control circuit
let's test it by removing some components
here i'm heating up a usb port from the back
there we go, it's still quite effective even if the fan speed is slow
it didn't work out quite so well with this SATA port, it melted before the solder would
final thoughts: damaging the adjustable power supply was my fault
but that doesn't change the fact that this thing is too big and bulky, it weighs a few kilos
in hindsight i would have been better off buying three separate units
just think if you have to carry your soldering iron somewhere, you have to bring the hot air gun and power supply with you
the hot air gun is hard wired and can't be unplugged
for a hobbyist i recommend buying three separate units
i wouldn't use these professionally, there's better brands out there like Weller or Hakko
they wear out and break as well, but they should last longer than one of these so it's money well spent
that's it for this video
do you use one of these?
or do you recommend something better? let me know in the comments
