Rookie wielder

[redrubi]

Looking for some advice on where to start with a wielding set-up. Only plan on using it for minor/mid range modifications on the TJ but would still like to start off on the right foot...thoughts?

Check the Continuing Education classes at SAIT under the Welding section.  These are very in-depth classes for the novice welder and well worth the money.

Well, wielding is one thing...like wielding a knife...just hold it and swing it around...easy.

Now, welding is another thing, and I have no professional experience there, so...I can't help ya.

I just took the Weldasaurus welding class as SAIT.   it was lots of fun and i got a taste of welding. 
now I want a Mig and a torch set up. to do minor welds.
I learned how hard it is to make your cuts and welds look nice.

get a 220 welder with gas

220 is good but if the  outlet for your garage isn't wired for it you will flip the breaker constantly and possibly not even use the full potential of the welder when in use. 110-115 is good enough for light work (up to 3/16ths thickness) and will get the job done. Make sure it is capable for running gas (Argon/CO2)  and good brand wire is a must. Brand of machine is personal preference also. They all weld the same metal its when you've been doing it for a while you notice the differences.

no princess auto junk either

If you got the cash buy a Miller DVI - duel voltage inverter - Mig
Got one at work, the only mig you'll ever need, it's sweet.
You can also buy a spoolgun for aluminium.

Ya avoid PA if possible. They work alright but replacement parts are hard to find and they aren't built to last. Cheap plastic parts on the inside that will wear out quick.

Don't waste your money on 110V unit unless you just plan to do body work. If your garage doesn't have a 220V outlet then either put one in/have one put in or get an extension cord to reach your dryer outlet(if practicle).

X2   on getting the 220 volt.  What I did was make a 50 foot extension cord for the welder and run it thru the basement window out to the garage.  I had to put a welder plug beside my panel in the basement to plug into to as some dryer plugs are not compatible with a 220 volt welder plug.

The extension cord was made with parts from an industrial supply house called Sav-On Electrical.   

Go with a 220 volt gas welder.  The 110 will work for for limited applications but I was amazed at the difference between the two.
