    Soldering gun (resized).jpg
    #1 2 years ago

    Picking up a Capt Fantastic project Pin this weekend and I'm sure there will be some soldering required as I resurrect this machine. I was out searching the forum and while there is a lot of information and opinions they seem to focus on soldering stations and circuit board repair.

    Not sure if a soldering station with a short cord is the ideal tool for E-M repair. I have an old Millers Falls soldering gun that says 100/140 Watt and a Radio Shack soldering iron that says 35 Watt. I'm thinking this is all I really need other than some 60/40 w/ Rosin Flux Core solder.

    Your thoughts?

    This is all you need in my opinion, that 100 watt gun is overkill.

    I use a bigger gun like the Millers Falls for getting the sockets replaced. Sometime that old solder needs a bit more wattage to loosen them up.

    But I agree, the smaller soldering iron should do most everything for you.

    Thanks, I like KISS (keep it simple stupid).

    Glad you mentioned the 60/40 w/rosin. I've been soldering for maybe 50 years and bought some leadfree stuff a couple of years ago in a pinch, yuck. Higher melting temp, and just doesn't flow like some good 60/40. Some solderwick is good to have to get rid of old solder.

    A 40-60W iron is probably all you need. As Griz mentioned, the 100W is likely an overkill, but keep it around just in case.

    The big one is over kill and the little one kind of sucks. Get something in the 50 to 60 watt range with a good tip and it will do everything you ask of it pinball wise. Weller is a good brand. Spend the extra few bucks to get temperature controlled and use it on your solid state pin also.

    Temp controlled: Good point Mad Dog.

    Funny you should say that, I seem to remember the last tine I used the little one it took forever to heat up.

    Know how many watts it is? Looks like the tip is pretty long.

    I use a 30-watt Radio Shack. It’s fine I guess. I did splurge for a new chisel tip.

    I think one of the biggest problems with people not being able to solder correctly is they use the wrong tip (i.e. use a pencil tip to try to heat up a big area or they use a huge tip on a PCB repair). That and the tip isn't cleaned prior to soldering.
