Well if you cant my drag link is *****ed!
I didnt see any problem welding 1.5 .250 DOM with my lincoln 220. I used flux core wire because I ran out of gas.
TIG would be nice but I dont know how.

It only has to be TIG welded to meet some racing sanction rules, but, you are not racing a $500,000 car at 160+ mph either. MIG is fine. What I do to test a piece of stuff before I go all out welding it is bending it in a pipe bender.
I like using 75/25 gas because it makes clean up (of slag) between welds much easier.
I never heard of it being more brittle. If there is a link to a welding site on that, it would be good to know.

just some advice, do some hella research b4 building you a 3link w/panhard or 4link setup, you dont want to spend all that money and not get all the benefits of a 4link, if you dont do it right, you might as well still be on leafs...
oh btw, i like your sig.

It was pounded into our heads that nobody, but nobody builds a trailer hitch with hard wire due to the shock loading. Local welding shops won't do it.
Also, for a welding certification plate, there are a flux-core and arc (stick) certification plates that have to be made and then ground and bent....without cracking or breaking. Guess what, a standard 230V hard-wire certification plate will not pass the test. The cold-lap from the insufficient penetration and cracks caused by impurities that the hard wire cannot remove (such as what a flux will do) will immediately break.
Nothing I do involves hard wire unless it's exhaust work or filling holes in sheetmetal since flux and stick don't particularly do a good [read: too much penetration] job on thin materials. Stick or flux-core all the way.
BTW, I'm not trying to be smart or boastful or even RIGHT!!! This is what half of my college money paid for, and I am really good at it. If there are other opinions, I will gladly listen to them.

Quad its still 2wd so any 4wd suspension would be an improvment. lol. Cody, Ive been welding for awhile and the only thing flux core wire is good for is new exhaust pipe. I dont even really liek arc welders. Id like to TIG the radius arms but i cant get ahold of a machine and i havent used them much but im more that sure my big Lincoln will be ok for this job.

Pretty much how I use it, but, I did use it to do some frame and bumper work. Guess I can't worry about it now, I already sold the truck.

As per the orginal question, yes you can weld it with what you have, and that guy was giving you bs.

I'm gunna have to agree....a good part of my college education was also spent in a welding lab, and it comes down to prep work and skill of welder. Hard wire will work fine if its done right. i still prefer tig to anything else, i think its easier to get a good weld, but thats just me....

Last I checked, downhill welding (any surface greater than 15%) is unexceptable no matter what kinda of process you use. Also I agree with mustange70 100%. Its all in the operator. If hard wire was unaccpetable for structural welding, they wouldn't be using it in the industrial sector. 99% of the welding here at John Deere is MIG with hard wire, and its used on everything from tractors, combines, and balers. Granted, its all 440V welders, but I still had to be 208/230V certified as a rework welder, and its not that hard to pass a coupon test if you prep the metal correctly before each pass.

alot of pipeline is done with a 6010/7010 down hand stick, its quick and less prep is needed with that rod. I singled out mig for purpose of the metal transfer it uses in the arc makes its a pita for downhand, also mig is used in pipe roots downhande, but that is when you can actually roll the pipe, and you ususally hand a decent sized gap to work with too.
