    Need to do a little welding on my frame, will be using a mig. Should I unplug CDI or does it matter?

    better safe than sorry.

    unplug cdi/ecu, battery, plugs or ignition coils and set your ground clamp as close to where your welding as possible.

    If your frame is Cromoly make sure you have the right wire for your mig,,, not the standard iron wire..

    And if its Chromoly make sure you read up about normalizing welds..


    Cheers.

    Chromoly welds just fine with mild steel wire... Now I only use tig for anything motorcycle related for a number of reasons but you should be just fine. I have welded lots and lots of 4130 tubing with ER70S2 and a tig.

    Going to load it in my truck( with every thing un plugged) and go to work early to do it. I was happy to hear mild steel wire will be ok. All I'm welding is my center stand stop brackets,a whooping 2 inches of weld. With out them the chain rubs the stand when up.

    Guess it depends on the chrome-moly alloy your using, and how well you do keeping heat down on the tubing.
    I've seen many cracked frames and roll cages when chromoly was welded with the wrong alloy and not normalized after..

    BTW std off the shelf wire from say home depot is very high carbon iron (At least in my local store) and he was talking mig not tig right?

    All I suggested was verifying the alloy and read up on chromoly weld normalization so he understand the potential issues..
