TIG vs MIG welding opinions for beginner

I'm trying to figure out what I want to buy right now.
I'm reading TIG is a bit harder for beginners but a much more reliable choice for welding.

This is saying MIG welding can often just melt a rod ONTO 2 pieces of joining metal and not actually MELTING into them.
Kinda like when you solder something improperly and it's just sitting ON TOP of the 2 wires....instead of melding them together.
Thus, causing a weak weld that's not readily visible to the user......which I've noticed ALOT of nice LOOKING welds.
http://www.ridgenet.net/~biesiade/weld.htm

I'm going to buy some video's and practice but I'm just looking for opinions on what this article is saying.
I've watched some Youtube video's too and alot of chopper builders are also saying TIG is alot better.

I'm just looking to do welds for a crossmember for my T56 and my tunnel hump mods to fit it in.
Obviously the hump doesn't have to be super strong but I think my crossmember does.

MIG vs TIG Is a timless debate.... Both when done right produce the same strength welds.... If you have never welded I would reccomend A Good MIG Machine.... 220 volts.... Sheilding gas..... plenty of capacity when it comes to thicker stuff.. A MIG will be cheaper to learn with.... Mix Gas instead of pure Argon.... Tungsten gets expensive quick when you are constantly grinding it because you stuck it in the puddle like a lawn dart Filler rod(depending on type) gets expensive because its sold by the pound not roll...

If you learn tig you will like it better.

Another thing to think about is if you don't have a detached garage I wouldn't even think of using a mig or stick welder, the sparks flying is a real bad fire hazard. The tig is more controlled like a torch no sparks flying around in corners of garage.
I've got a mig and didn't think about that...I only feel compfortable using it outside.

If you're not going to do any big jobs neither will be worth the fuss...ask Keiser (Doug), he's trying to sell one that never gets used.

Tig does make a great weld but is slow, very slow. Mig is easier to learn and much quicker. I have both and avoid tigging unless it's a real thin item, aluminum or I need a more delicate weld.

ace i have a mig and would feel very comfortable doing what you need done with a quality mig. if the floor pans are good a mig will weld floor pans nicely. thick metal like cross members is a piece of cake. just make sure you use a gas attachment mig and not flux core wire.

i havent ever found a need to buy a tig although i want one and if i welded aluminum i would own one but...

You can do much more with tig welding if you are really good than you can with a mig welder. Both types have their place. You can even weld aluminum with a tig welder much better than you can with a mig welder IMHO. Lots of aluminum and steel parts on our airplanes are actually tig welded. Hope this helps!

Mig is easy to learn and does most things you need and is more forgiving on metals that are not an exact fit. If you get good at a Mig I would think then you would move up to a Tig. The guy that taught me to set the heat with a Mig and welding upside down and other things is amazing and has a Tig that he would use and he said it would take him a bit to get reaquainted with getting the Tig weld correct if he did not do it often, but Mig doesn't take much at all to get going again, a couple general rules and you are off to the races. That being said, I wish I had a Tig now because I'm ready for the next level. Mig, good starter welder.

Mig is versatile. Tin work as well as cage with the same wire, get your setting right and it can be done with a 220v Mig and Argon/CO2 gas.

I would go with a MIG with Stargon/Argon shielding gas . I can't even tell you how much I use mine. I weld aluminum with it too...use another liner,tip and drive wheel with aluminum wire, argon gas...my aluminum welds are bitchin with it.

mig is point and shoot (practically) gm taught me in a shift on a moving object!(definitely not rocket science) . tig is manual wire feed, foot pedal, and arc distance all at once. if you can tig , you can mig. if you can mig it doesn't mean you can tig though. and a huge plus you can tig non ferrous metals

Is the Home Depot Lincoln Electric one's a good brand to get ??
I seen Menards, Home Depot, and Lowes all have different brands.
Wasn't sure if I should get one of these or a Miller or something else.

Okay, I'll look into this then.
I don't understand the shielding gas part with Argon or the other stuff.
I thought I read it can be toxic if inhaled.... ??

Thanks , I'll look into that more.
There's a place by me that sells welding training video's.
I was going to buy one and a welder and just go to town with it experimenting.

Thanks Kik, I'll inquire.
Yes, my garage is attached.....my MBR is right above it.
So maybe out in the driveway is better eh ??

I have MIG and TIG machines and they both have their uses. TIG shines for small, critical jobs and it's ability to weld different metals such as aluminum, stainless or cast iron with just a change of filler rod and a flip of a polarity switch. You can weld 2 razor blades together if you want. Downside are, it takes a little more practice, is a slow process and uses much more gas for the same amount of weld, especially if you have gaps to fill. It would probably take at least 5 times as long to weld a floorpan in with TIG as it would with MIG. If I was forced to only have one welder it would be a gas shielded MIG. If they say MIG is like soldering then they don't have the voltage set hot enough to penetrate the base metal.

.

One thing to remember, and why I had to buy a TIG also.
Moly cages require TIG welding. Since all 3 cars are moly, I bought a TIG.
My neighbor has a MIG & stick, so now I'm covered.

As mentioned, a TIG has a lot more options & control.
It is also a lot harder to get good. You have a lot more going on, and takes more skill, physical & mental.
It's a lot easier flipping a switch on and pointing a mig at the seam and going for it.
My neighbors son is a lazy idiot, and he picked it up the 1st time.

TIG machines are pretty pricey, no?

What I did was pick up a mig and I am trying to learn on that. If I get good enough I'll maybe move up. But I doubt it. I won't be making my own rollcage.

Sweet!!! So I'll be just fine then.

Actually I've seen those little race cars at the drag strips for kids.
The long thin one's with a tiny motor in it. I've been wanting to learn
to weld so I can build my kid a little race car too.
