I started with a Lincoln flux core machine I bought at Lowes about 10 years ago. I upgraded with a MIG kit a year ago. The quality of my welds went up exponentially. I say bite the bullet and buy one. It's a useful tool to have around the shop even if you're not doing car restorations. I am always fixing and fabricating stuff.

This is what I am talking about, This is best way to fix sheet metal hands down no BS this is how its done the rite way! Anyone who tells you different is wrong.

This one too is good

Forget the Migs forget the Tig
Gas Is wear its at!

A Mig welder is just too Hot too much heat and the bead is extremely hard and brittle The idea of stacking thousands of spot welds to patch a panel has been accepted industry wide it doesn't mean its the rite way to do it.

I'm confused now, I was thinking of welding with acetylene/oxygen but thought it would apply to much heat, or at least more than mig. I found a great set for sale used but now it's gone, complete set with torch tanks and cart etc. Is it possible to weld overhead with gas, like when welding the inner wheel well?

Yes you can weld over head with gas again look at the size of the gas torch he is using in first video it is a small set up, Not your Dads or Uncles old Cutting torch set up look at how much heat is going into the panel the area bluing just an inch or two then notice as he welds he hammers down the weld and works the panel with on and off Dolley hammering technique to hammer down the bead and straiten the panel distorted from the heat both at the same time, also notice that he is only welding about an inch at a time and that he does jump around panel.

You have to be able to get to BOTH sides of the panel as Chevman says.
It can be done with two people but its not easy as it sounds

Just depends on what your welding up too, I wouldn't gas weld heavy structure necessarily I would probably use a Mig instead but I have all three set ups myself its all in what your doing and what you want the results to be.
Using the right tool for the job perse

I would like to know what that guy in the first video is using for filler rod from that spool looks like a really soft metal almost like a solder but i know its not solder, Also If any one knows for sure I am still trying to find a source for SK or AK 18 gage sheet metal in Nevada? Know one knows what the heck I am talking about when I call steel supplies out here its like I was speaking some sort of foreign language

I got some thinking to do, which way to go. Take in for consideration ease of welding, quality of weld, and of course cost. I will have to take some time and figure this out, any other thoughts, opinions or experiences anyone is willing to share feel free to do so, thanks.

Doing a full restoration is a BIG task all by itself don't kid your self its a no joke deal it takes a lot of time and a Lot of money no matter how you do it not to mention a heck of alot of determination.

I suggest finding a shop and other guys restoring cars and help each other out :goodjob:

Oh While your thinking about things do not forget about Body panel adhesives while many still turn there noses up at it I really do believe its the way to go when used properly. Its every bit as good if not better than welding in my opinion plus you don't have the heat warping from welding to contend with.

I had no illusion the cost of restoring an old muscle car was going to be considerable. But keeping the costs under control I'll manage to go further with the funds I have in mind to use. I still have 2 daughters to help through university. I also know it's going to be a long haul, so I'm prepared for the headaches and rewards. I want to thank everyone for their help and input, and I am not done asking and learning from you all.

I was out there yesterday Practicing what I am saying with a 00 tip on my gas welding set up using low pressures, I wont say I was doing great but its not bad for an amateur restorationist. I will be doing more gas welding in future myself its just easyer to hammer the bead out

I used to weld for a living many years ago mostly mig and stick, so I am no pro by no means. But I will figure it out again, practice makes perfect, or at least close to perfect in some cases. Still looking for acetylene and oxygen set.

For sheet metal gas welding, I would suggest low pressure regulators, with a small torch and hoses. I have a set from Dagger tools and I like it, but I wish I had spent the extra 25% for the meco from TM technologies
