    Hate Soldering !!!!

    Folks,

    3 bloody hours to solder a pair of balanced patch cables. I dont know what
    I do wrong ? I can tig weld freaken Titanium,but this thing is kicking the crap out my EGO (some think that aint such a bad thing) I think my little 25 watt soldering iron is the problem. I think I need to buy a new one. OK , so I dont use it very often ,but I do think its time to practice what I preach and find the correct tool for the job. !

    WHAT SHOULD I BUY ?

    TIA Rich

    hello Rich
    The same quality as your router?
    If so then these (or newer)

    how tough can it be?

    3 hours? i'd fire you.

    ps. My wife ALWAYS carries a small roll of solder in her purse, just in case.

    Andy,
    It was 3am when I finished. I could'nt get the solder to run. Then when it did,
    I melted the insulation and kept getting a short.I thought I'd run out of bloody cable. Anyway, I stuck at it and WOW. I have never heard a dac that sounds like tubes until I got this MSB . The DEQX has been relieved of dac duty for the time being. Analogue Balanced was quite an improvement over coax Dig

    Bo, really did the business for me with the room compensation.I'm in heaven

    Only kidding, I find soldering the screen a real pain as it burns everything else.

    I can solder a pair of XLR's in about 2 hours I have a few to do here and have been putting it off for weeks....

    Next time I will just buy them already made.

    Soldering tips

    Use cable that is twin conductor plus foil screen with a drain wire commonly known as FST ( foil screen twin ). With this you do not have the nuisance value of the braid.

    XLR types --- Cannon Switchcraft Neutric Amphenol and generics on the inside of the conn. at the back of the pins there is always a good 'well' . You want to give all the required pins a good tinning, ie flow solder onto the contact and heat it until the bond is visibly 'WET '

    Prepare your cable by stripping back and trimming to the required lengths. Common practice is to keep the screen leg shorter than the two signal carriers ( pins 2 and 3 ) Tin the exposed parts of the wire ONLY until the solder has flowed and is bright then remove the iron.

    Mount the pin set into a vice or a mating socket bunged into Play Dough then heat first pin 1 till the solder melts to a bright liquid. Feed the screen wire into said molten solder and the tinning on the wire will melt and become shiny. Your iron is in contact all through this. As soon as the wire tinning becomes bright withdraw the iron, hold steady and in a matter of seconds the joint will cool solid.

    Repeat for your signal conductors and watch out for your pin layout because it changes if it is a male or female contact.

    RCA / phono These can be quite varied in the contact arrangements inside and it is a good idea to have some small heat shrink sleeve to cover the tip ( + ) connection Other than that use the same method as above for the soldering.
    When unbalancing twist the screen and the -ve conductor together and solder to the outer ( shell ) contact

    1/4 jacks -- as above

    I can do XLR conns easily with a 15w iron.
