*LEAD IS LEAD* The less lead we dig out of mines and pull into our working and living areas, the less lead will be present in perpetuity where we live and work. It does not matter that our work product ends up free of lead - the lead used lingers somewhere. Thank you for the 700°F-725°F range suggestion for lead-free solder, I will try the 716°F for my through-hole, electronic component soldering.
Hakko's iron is very good, but the interface is a dumpster fire. They should have used three buttons and nobody would have had the need to read the manual to avoid offsetting the tool. (Thankfully, it can be reset to factory settings quite easily, but still...)
Thank you for the kind reply! I will post the code I used for the video to my github and link back here (it might take me a couple days). For short explanation, if you set the pins up on a port or in an array you can step through and set the dac state with a simple state machine quite easily. The output of the comparator goes into a GPIO pin used to see if we are high or low, based on the result we either keep the current pin set or clear it before moving to next state. You can configure the state machine to match the number of bits plus a setup step and final convert step, after that its just a mater of stepping through the state machine with a clock. (with some creative programming you can probably streamline this down) I am working on a follow up where I characterize the ADC and calculate the DNL and INL hopefully you find that one interesting too!
IF YOU ARE GOING TO POST A VIDEO "HOW TO" AT LEAST LEARN THE CORRECT PRONOUNCING OF "SOLDERING" ru-vid.com/video/%D0%B2%D0%B8%D0%B4%D0%B5%D0%BE-6PSAVz0d0vQ.html - YOU DO NOT PRONOUNCE THE "L" IN "SOLDERING"
great video...i realize its 9 years old but you're constantly moving closer to and away from your mic. Its pretty harsh on one's ears if you're using earbuds / headphones as you go from a whisper to far too loud. This is still one of the nicer videos on YT concerning the subject though.
Perfect video my miller started acting up today working sporadically hitting the trigger. Can't complain it's my only break down in 25 years with this welder.
Glad I was able to help, Agree on can't complain its the only failure with my DVI2 in all the years I have used and abused it! Thanks for dropping the comment!
Great soldering station. I've had mine for 7 years and still has the original tip nice and shiny.

G´day I have recently acquired two used millermatic 252 from a workshop. One has a bernard gun and it´s ready for aluminium, everything is working fine. The other one is set up for steel, it was not feeding wire, I noticed the contactor was not working the 32v dc one, I installed a new contactor and I listen the dock sound right after I turn the machine on, turns out it was not feeding wire still... start playing around with my multimeter checking the voltage that goes to the wire motor , unplugged the wires, plug them back in and the motor start working, after that I was playing around and testing it and it was working fine. Next day It was not feeding wire again ... I am sorry for the long text .... just to see if you can understand and maybe help me with this... after some testing I noticed that if I put the bernad torch it works fine, and it also works with the original torch but only when the metal part of the torch is not touching the wire feeding drum ... triggers works fine and everything but as soon I touch the metal part of the torch inlet with the feeding drum metal structure it stops working .... thanks for your time all the advice is welcome cheers
Hey, what an excellent video, thankyou. I had question, im repairing a headphone that as wire disconnected from the post, I think I have two option correct if I'm wrong. 1. Re heat the original solder and afix the wire. 2. Add abit of lead solder to the post without removing old solder. But I'm not sure if the original solder is lead free or lead does this matter if I use lead on top without desoldering the original solder?
You probably already figured this out, but you can mix and match in this instance. Adding leaded solder will decrease the overall melting temperature of the solder joint and of course mean its no longer lead free. You can also use Bismuth based solder like Chip-Qwik which can lower the temp and make it easier to rework. Hope this helps!
Once your Hakko is out of warranty and it shits itself forget about getting a circuit diagram for it... Hakko will NOT supply it because its confidential.... Lol really Hakko, its a frigging soldering iron and not a rocket you muppets. People don't waste your money on this overpriced junk. Hakko was great in the 90's but got money hungry
the main difficulty is to get the iron temperature high enough but not too high as that would ruin the iron tip (assuming SnAgCu) . Since you are using very little solder there is little thermal conduction happening, if the land pads are connected to large metal planes on the PCB any heat from the iron is quickly dissipated and it becomes difficult to wet the land pads even with a lot of flux (flux does not conduct heat as well as solder, but it reduce surface tension of the molten solder). I find that practicing removing SMD components from scrap boards and soldering them back (with all the cleaning and flux steps) let you get a lof of feel for these things : flux, iron temperature, amount of solder on the tip to improve thermal conductivity. Given your video i suspect you are working at fairly high iron temperature and your style of using reflow to position smd's probably will not work with a smaller iron. A big tip like yours will get in the way in a denser layout.
Love your videos thanks for all of them I’ve learned so much about soldering since I’ve subscribed. Thanks for posting watched everyone can’t wait for the next one to come out. Love the Hakko products
Love your channel thanks for the post been a subscriber for while now love your Hakko soldering tips really learned a lot for tv repair. Have you tried the Hakko tip cleaner if so what did you think about it. FT700-05 this will probably be my next purchase. Been getting a lot of my equipment from NES ELectronics authorized dealer
