12 volt soldering irons
« on: January 07, 2015, 10:26:53 pm »
It would be good to power a soldering iron from the car battery
while working on the car, but Weller wants an astonishing $125.90
for a 12 volt soldering iron, No. TCP12P. Seems excessive, why
can't i just connect the battery to a $5.00 iron?

I bought a 12V iron from Radio Shack several years ago, ISTR it was about $20 or so.

Alternatively, how about an inverter, or a gas iron?

You can get on eBay unregulated DC irons, some are just typical 936 handles direct wired...



and there are proper drivers for various handles which can take a DC voltage down to 12v, add your own handle...

I have one of those Weller irons and it is really very nice !  40W but the temperature is controlled by a standard Weller  Curie temperature tip.

I have a Weller gas powered one, and I must say, it works quite well for working on cars etc.

I have a butane powered one, I use it all the time when there's no power near by.

Butane, but you have to really be careful around all of the carpet and vinyl so that you start one Hell of a car fire.

12V on a 24V/50W iron will not produce 25W, it will be 12.5W...

A standard soldering iron doesn't use much power, how about using a small inverter with a 120 V soldering iron?

Or try a butane soldering iron. I have one and I really like it. I pulled it out the other day when I needed to do a small job just a few feet away from the bench, instead of using a basic iron. The biggest issue with these is controlling the temperature manually.
