    I have been doing a considerable amount of welding over the past nine years and what I have found chasing cracks is this...

    Start by grinding out the weld as stated before, and you be sure that you get a good weld to start with, then weld well beyond where you can see the end of the crack. At the end of the weld you can do two things that work well...drill the hole as mentioned before, or you can weld a slight arc or "C" shape that "caps" the end of the weld. Both have worked well depending on the application.

    In this situation, I think I would NOT box the frame unless you are going to box the entire length. At the end of the boxed section you will generally see cracks forming if you are using the jeep off road much.

    There's my .02 cents!

    I agree with jplumb about the technique on how to end your weld. Although I only have 1/2 the years of welding experience as jplumb I still agree. As for using a 110v mig......they do work, racecar crews use them for building and repairing because they are fast and do so with a good result, my personal 2 cents are if you are going to use a 110v welder try and get a 140amp one because 1:better duty cycle rating, 2:slight bit better power so you can use it for bigger jobs in the future if need be. Around my area you can goto the local tractor supply and get a hobart one for less than $500. I don't know what it is like in florida though so just look around if need be. Northern tool has them also. good luck with whichever route you take.

    I welded quite a few cracks on my frame with a 110 volt. I don't know how long it will hold, but with a 220 volt welder I wouldn't even be concerned.

    I agree strider. I use a 250amp 230v lincoln. this welder has good power and welds good. keep in mind it is a stick welder though. The mig experience I have is with a miller 210 and 251. both 220v. Also with a 140 handler 110v. Haven't had too much of a problem with any of them, but I see where you are coming from. If you have access to 220 volts get a larger welder. :twisted: good point though strider. :)
