I got my version 3 wire kit today, and I was wondering if it mattered what way you solder the trigger contacts. I need to solder the wires to the trigger switch, do I need the positive wire leading to a certain piece, or can I just solder each wire to ether one?
It's going in my CYMA AK74un (cm035a). Me and my dad tried for like 1 hour, I went out and bought a new soldering iron and everything. the thing will not stick. Every time we get the solder on there and move it after it cools it just falls off. I suck at soldering, and I'm going to the hell survivors game, I need this fixed.
Yes I've been doing that, my dad has to we tried a lot of things. Every time it would solder right, it was so weak it would just pull off. I've watch videos where the guy soldered deans connectors, 5 seconds later he pulled on it hard and it didn't budge. I'm not sure what to do. There is a guy at my dads work who solders but the problume is he won't know how to do it right.
Ok, so I'll try to help over this thread, unfortunately soldering is kind of an art, and is much easier taught in person.
The scoring is correct, I usually would just run some emery cloth on the surface. What your after heat is cleaning off the oxidation do you have a hope of the solder bonding to the metal.
Next, get the soldering iron tip clean. To do this, melt done solder with the iron, then wipe the tip on a wet sponge. Repeat until the tip is shinny.
Now, get a little solder on the tip of the iron. Touch the iron to the contact. Touch the solder to the contact, near the iron, but don't touch the iron. If the solder melts, your iron is powerful enough for the job. If it doesn't, unfortunately your SOL. Assuming it does melt, keep the iron on there long enough for the solder to wet out. You will know when it happens because the solder will flatten out instead of ball up.
Use pretty much the same technique for the wire. Next, touch the wire to the contact and heat the pair up. Put a little extra solder on it and keep it all held still until it cools enough to solidify. This is important for a solid connection.
The solder you have its not great, but will probably work. I'm a bit of a solder snob, but you wouldn't probably want to buy solder that costs more than your iron.
Well I finally got it, thanks tank for the help, and everyone else. My solder kinda worked (: it's a bit sloppy but it will do.
On that note, my gun wont work, it fires and no bb's come out. Then when you take the mag out it spills 5 bb's everywhere. If anyone is a good tech I will pay you to fix it. I will post this up in a different thread.
