The Solder Sustainer

(1/4) > >>

xrunner:
One handed soldering (well, plus one foot too)!

no you want to put it in vise so it does not shake and feed in the solder at the angle that is appropriate to fill the joint not transfer it from the iron like a pipette.


IMO does not work right. I see alot of youtube auto feed solder contraptions in chinese factories that are probobly causing the wire to break because they think they can do it but you see in the end its never correctly soldered

I think its made for drama TV where they need to fix something with an announcer reminding you that the time is running out and the next round of the competition almost started

That might be an illusion. See the screencap below where the iron is heating the pin and pad, and the solder is going on the pin. When viewing the video that would look like loading the iron, but it isn't.

coppercone2:
I don't think you are getting the best feed angle and its very liable to over feed solder.

It is fine for some field repair in a competition of robots or whatever but I would not assemble electronics this way.
Maybe if you get enough skill with it you can do a similar job for very good fit up parts


I find for the neatest solder jobs you need to change the angle and feed at a shallow angle

I think TIG welding perfects the parameters you need. Its not the same process but I find when I solder its something like that usually. you get the wide  V

I think it's quite cool :)

Feed shouldn't be an issue because you control where the solder is dabbed, and how much, by moving your finger. The auto-feed mechanism just ensures there's enough hanging free to be useful - it doesn't push a specific amount onto the work.

I imagine it would take some practice to perform two functions (moving the iron, feeding the solder) at the same time with two halves of the same hand. And you can't put it down easily - typically I grab some part and position it, grab the iron and solder, do the biz, put the iron down while I get the next part, etc. So that's not my workflow. However, being able to manually position a part with one hand whilst soldering with the other is certainly an attractive feature, but one that comes with baggage that may overwhelm the benefit.
