Default Is a 60w solder iron strong enough for electronic soldering?

I need to solder and desolder some resistors and capacitors.
I have a new 60w basic solder iron, is it ok for that use? my previous
one was 30w.

A 60W soldering iron might be a tad too much if it is not temperature regulated. For basic PCB soldering, something around 25W is more appropriate. Higher powered irons are often seen used in electronics, but most of the time these are temperature regulated. Otherwise, you'll quickly fry your board and the components on it.

Yeah, if you bought the 60w because the 30w was too slow, buy a chisel tip for the 30w iron. Chisel tip is a cylinder right out to the very end, which is flat and about 3 mm wide and .5 mm thick. If your 30w iron is not supported by different tips, buy a Weller WP25. Get the tip on the same freight order, it comes with a useless pointy tip, too.
If you bought the 60 because the silver solder won't melt-join the club, it doesn't work very well. I use 65/35 tin lead, which is practally banned in Europe because of all the lead shielded KCRT's businesses dumped in the landfills. Update your profile, your location matters on what advice you get. If you live in Europe you need a very expensive iron, although wave soldering by professionals works better. (and is why big companies are in favor of the lead solder ban, repairmen can't afford wave soldering).

An unregulated 60 watt iron is good for for very high speed work, especially on large connections.

Even a 45 watt iron can be too hot for PC board work, but with a little care it makes clean connections quickly.

30 is actually quite useful and relatively maintenance free if good enough quality. Avoid anything with a set screw for the tip.

I would go for a smaller wattage gun in your case....for me...I use a 2000 watt. I just want the gun to LOOK at the joint and solder it. Less issues that way.

I use a 60W Hakko with a light dimmer to adjust the power. Full power for large connections, throttle back for PCB work.
"Fully on MOSFET = closed switch, Fully off MOSFET = open switch, Half on MOSFET = poor imitation of Tiffany Yep." - also applies to IGBTs!

I have always used 15W on PCB, and 25W for point-to-point. Normal leaded solder - Ersin Multicore is about the best 'normal' brand in the UK.

Wouldn't using a dimmer change the temperature of the iron ? (instead of the wattage)

I would have thought that wattage = mass of copper in the bit.
A high wattage iron shouldn't run any hotter, its just able to heat up larger objects.

OP: 30W is more than necessary. If your solder joints are coming out bad, you've got some other problem.

Thanks guys.

If it's an unregulated 60w iron you can use a variac for temp control, if you have one.
