if you are a good welder id say the stick is stronger, but the mig sure is better looking..

as long as its a 220 volt either one will do fine.

MIG/TIG, you will be moving in circles and a stick is a pain in the buttocks. I would definately stick weld the seams of the frame though. As far as stronger, it's all about penetration of the welds. No penetration, no strength.

Depends on conditions. You must weld with stick if you are not in a shop. A slight breeze will blow away the gas on mig and cause perosity(swiss cheese holes). I don't recomend using flux core wire(no gas). Dual sheild(both) is the best. But for an inexperienced welder mig is by far easier to learn. Just remember while building that your life and your cars frame depend on these welds in an impact. Take your time.

Hope this helps,
Time

I tack together with a 110 mig then finish it with the 220 mig welds are cleaner and better looking and I think the wire feed is easier to use. Eddie

The weld can only be as strong as the metal you are welding.

MIG's are for motor racing. Sticks are for stone rakes. hehe What do the major chassis builders use? mig or tig! What does the local John Deere dealer use? stick.

You should use MIG it is the most efficient for welding roll cages, frames, etc. On thin steel ( 3/8" and under) MIG is by far better than STICK. MIG produces a stronger weld than STICK, the wire is typically an ER-70S-6 which is a 70,000 LB tensile wire and to use stick you'll have to use a 6011,6013 or 6010 rod which are 60,000 lb rod 7018 is a flat and vertical up only rod. With STICK you will have a problem with welding too cold because you will have a rod that is thicker than what your welding ( 1/8"/.125" rod and .095" roll cage tubing) so it will take more heat to melt the rod than what your welding. I was a welder for many years and now write welding procedures for a living and I weld all of my cars with MIG.

First, 7018 is an all position welding rod, the "1" in the 7018 means all position, 7024 is a flat-horizontal only rod (2) but anyway I would recomend mig welding it because stick dosen't fill gaps in thinner material well at all. don't use a 110 mig eather because they don't have enough power and your starts on your welds will have no penetration. Ideally you would use a tig and purge the inside of the tubing with shielding gas during welding, but that takes more time and money than I and most racers have!

i have a 110 mig and a 220 mig and a 220 tig. the 110 mig gets used on most everything, the 220 mig is used on major frame stuff, but small brackets and bumpers the 110 is used. the next car will probally be all tig welded.
i should note the 110 mig is a new miller 130(i think, have to look) really suprised me for a 110 volt welder, and works great on small things and odds and ends.

As long as you achieve proper penetration, fusion,and weld build-up the process and size of the machine used is irrelavent.

I have a millermatic 135 and have been pleasantly surprised with the performance, versatility and ease of use.

Honestly would you try to weld up a roll cage with a 7018 rod, If anybody would use two different mig welding machines is beyond me. I personally have welded up a stock car with 6010 rod, I really didnt like it because of all of the sparks and burns, I have mig welded up a few roll cages as well, also I Tig welded many sprintcar chassis and many drag cars as well. The ideal way to weld "your" cage would be which ever process you feel most comfortable with. If you Purge weld a roll cage when your Tig welding it do you know how long it would take for all of those tubes to fill up with all that argon. Come on now its a stock car, I do understand it should be a quality rollcage with sound welds. Just be sure to watch out for those wild sparks because you might set yourself on fire. Its only a stock car dont make it harder on yourself.
