Ok I went to tack the back half in so it would stop moving around. I tacked each side, and decided hell, I am under here already why not put a couple of welds in place to make sure it does not move if I have to put a little pressure on it. Can you guys look at the pictures and tell me what I am doing wrong. Both of these welds were made at the exact same settings on opposide sides of the car, and I moved the grounding strap and attached it to the same point on each side.

I'm no professional welder, but I'll venture some tips. I'd guess your biggest problem is poor movement of the tip. If you're welding vertical you need to make bigger circles to let the puddle stay smaller and cool quickly so it doesn't flow. With MIGs I've found that slower wire speed and less heat seems to be more controllable, especially welding vertical and upside down. My welders tip likes to be pointed at the area I'm moving away from. Make sure there's no paint and no wind blowing the inert gas away. Get the wire closer to the notch where the pieces come together and make circles as you move along to move the puddle from the side surface to the box tubing and back to leave the stacked nickel look and to get penetration on both surfaces.

yes circle circle circle, try holding the hand with the gun up with the other hand to keep it steady.

I'm no pro either...but what those guys said, and it looks like you need more heat too. Doesn't look like good penetration.

Problem solved, has a ton to do with haveing over 150 foot of extension cord going to it through a Surge Suppressor. Took and used a shorter extension cord, and pluged it into the garage, and the problem was solved.

By George, I believe he's got it..... You have to have enough heat to penetrate so the two surfaces will hold together, and circle, circle is also correct, you will want it to lok like a row of quarters on thier edge. Practice with several pieces of similar metal....

In a couple of weeks, I have a guy that has offered to come help and make sure I can do everything I need, and that everything is all set up, and we are going to get it all taken care of. He just wants to help me get the cage certified so I can run it and as he put it "So I can come see the beast run!" Guy has been a certifed welder in the aircraft industry for the past 30 years, and I really value his opinion, and also really appreciate his offer to help and to make any critical welds I may be concerned about.

I got my own helmet here and when he comes he is not only bringing his helmet, he has offered to bring me a leather apron, and also a set of sleeves to keep. Then he is going to make the first couple of passes with me watching, and then he is going to observe and kibbage. After that he will just watch me work, as I go after it. Really a great guy!
