Ohm's law?

so, i have a broken soldering iron, and i want to fix it

can someone =smart= calculate the required resistance of wire at 120v ac
i don't care about the amperage, as long as its under 2 amps

please give me a range of resistance, i don't like to trip fuses, (my parents hate that!)

Picture of Ohm's law?

I had a 40W Weller burn out on me once. It overheated.

It was glowing from the heat...

i left my iron on for a couple hours (not before it broke) the tip was glowing slightly red, very, very dimly the little grip was getting painfully hot, so i insulated it with double sided (sticky) foam, and electrical tape

60 Ohms is 2 amps but that is 240 watts. more then most soldering irons, unless your soldering pipes... Most small irons are in there 25 to 40 watt area 576 to 360 Ohm area....

thanx!
. Keep in mind that the impedance will be higher than the resistance. How you wind your coil will determine how much difference. Even 360 ohms resistance _may_ turn out to be too much impedance. May not make enough difference to matter. . And make sure you use the right type of wire/insulation for the high temps you'll generate.

impendence? i'm not familiar with that term, i though impendance was/is resistance

thanks!
What type of iron are you fixing ???
Sandisk1duo (author)  Big Bwana9 years ago
40 watt weller
