On the right is my beloved Hakko 936. I love this iron so much that I have a NIB spare in my closet that I bought when they discontinued it. It's many revisions old but the newer ones all look like Fisher Price toys to me so I never saw the need to upgrade. Then a random trip down the YouTube rabbit hole had me discovering that there all sorts of newer tech out there so I bought myself a Pace ADS200 direct heat (AccuDrive) iron.

The 650 is Fahrenheit. There's a program setting to convert to Celsius as well as a host of other options including my favorite: auto-off. It also has an auto-setback timer so it will lower the temperature when it senses that it hasn't been used for a certain amount of time.

The base is a US-made, all-metal 120-watt monster. The iron is a "cartridge iron" which means that the tips now contain the heating element along with the ability to measure the temperature, all of which means that it should be able to solder the smallest components then move over to soldering guitar pots just by swapping the tip, which Pace says you can do while hot (it comes with rubber coated tools for this). The Hakko is about 60 watts and soldering something like guitar pots was always an exercise in frustration. In fact, I would always just use my Weller 200W gun for that. Let me tell you, those big old guns are not the most nimble things to be waving around a guitar.

The new iron has a much smaller handle and the tip is much closer to that handle than on the Hakko. That's going to take me a while to get used to since I've been using the Hakko for probably 15 years. Supposedly they got surgeons or surgical tool people to help them design the new handle, but I don't know how true that actually is.

Here's a pic of the tips removed from both irons. The top is the Hakko which has the traditional heating element with the tip sitting over it, held in place by the barrel. On the bottom is the Pace, where the tip *is* the heating element and is replaced all in one.

I don't have the larger tips for it yet, but I am dying to try it on some guitar pots because it is supposed to be night and day from anything I've used before.

The Hakko iron was probably around $100 new, which is what they sell for now. The Pace was $330 as a kit with three tips, the iron, and the iron stand. all of which are made of metal, BTW.

I kind of which I'd bought it before soldering the 2000+ solder points on my relay computer!

I like PACE equipment; we used PACE in the Navy, and I promoted PACE equipment throughout my career in electronics manufacturing.

For what it’s worth I found soldering the back of guitar pots was easier with a chisel solder end.

If you look closely you'll see that both of the tips in my pics are chisels. They're just really small. This is the one I'm getting delivered for guitar pots:

Nice! I actually looked at that because it's still a current model. I also looked at the newer 350, but both take up too much room for the space I have right now. Also those desoldering stations are like $1700 fully loaded. Actually the 250 you linked to is more expensive than the 350 even though the 350 has newer tech and I couldn't figure out why.

Thanks for bringing this up - I have a Metcal Mx500 that I got free together with 4 PACE soldering and desoldering stations, when a neighbour company was quitting. First I thought that the switch between two tips was ridiculous - but soon found out, that by the time I pick up the second one it is hot already. Fantastic tool. The tips have gone bad and I have not used it for few years - but just checked and decided to order some new tips - one fine for PC-work and one bigger for pots and cables.

Yeah, those big PACE Kits are for doing full-scale PCB repair, both through-hole and SMT. I also used their circuit trace repair kit and gold plating unit.

How do you like the Metcal? They're supposed to be the gold standard but all the ones I've seen were ugly and huge.

Depending on which Pace stations you got I may be interested if you're selling.

I simply loved it when it was still working - it heats up in no time. At first i did not pay any attention to it, because the bunch was this plus 4xPACE - but a friend who has been professionally soldering happened to see them and immediately pointed at Metcal telling me to keep it.

Having been used to regular Weller taking minutes to heat up i first thought the idea switching between tips was odd - so much waiting - but since it only takes few seconds, it is actually genious.

When it eventually quit working I simply switched to next one - PACE - but this thread brought it back to my attention - it might well be, that I simply need to get two new tips. They are less than 20€ a piece.

And the model is X500P

Dreadnut may know more but I believe Metcal invented the whole direct heat concept used by Pace, JBC, and the new higher end Hakkos.

I also have a Metcal MX500P that I bought at a company liquidation. For $50 I got the power unit, work stand, half a dozen tips, and enough solder to sling for a lifetime. It may be somewhat large and ungainly, but it's an amazing workhorse tool.

The thing I like best is that it heats up really fast to the perfect temp, without going too high. I always used heatsinks before to protect components, but I don't feel the need to do that anymore with the Metcal.

Yeah that's the same tech that's in my Pace. It heats up to 650F in probably three seconds where my Hakko takes more like 45.

When the tip size is properly matched to the size of the solder joint, the soldering operation should take about 3 seconds, on and off. More time than that results in overheating, less time than that may result in a cold solder joint. You can make it happen quicker with a bigger tip or higher temp, but you will lose the time/temperature parameters.

Here's a quick and ugly vid of my first attempt at seeing how the larger tip fares on a random guitar pot. This is on the "pipe guitar" which is an S300A that is kind of a wreck. Apologies for any technique shortcomings both soldering and videography-wise. I was soldering with one hand and holding my iPhone with the other.

The tip is a 1/8" ultra-performance chisel tip that cost me $14.59.

Yeah well soldering to the case of a pot does require a big tip!

Certainly, but a big tip without the juice to heat it doesn't help much. This thing blows my 200W Weller gun out of the water. Of course that's got some state of the art 1950's tech in it along with one of these extremely high-tech tips:

I've also got my dad's original metal-cased Weller gun from when he would drag me around to people's houses to fix their tube TVs. That thing's gotta be from the '50s or '60s. It has an ancient screw-in bulb like you used to see in little flashlights. Looks just like this:

Also, I just found this and felt the need to add it. :)
