...Also with the Gold lens be very careful not to scratch the coating on the front surface. You don't want to use one with even a tiny hole. Just put a good clear lens in front of it. The newer lens now day's may be better than the ones I used 10-20 yrs ago.

Agree, two or more helmets is nice and cheaper. I still nodded head even after using the auto lense for decent amount of time. Then switch back and forget to nod with regular helmet and see the light.  Heck I nod at the flash of a bulb. Also for sure about the scratches on the gold plating, inspect regularly.

It should look like stacked coins that got knocked over all around without too much undercuts. It can be done.
Call me crazy but, a semi-automated process like a wire feed MIG welder, is designed to weld continuous beads (obviously it can be used for tacks and short welds too), not stop/start to make the weld appear like it was done with TIG.
It's like those that can't use a TIG well try to make the same bead profile with the MIG cuz its easy to operate.
Just practice with the TIG and leave the MIG for welding the trailer

Not doubting you, however I posted your photos in a chatroom after explaining to a welding buddy of mine how impressed I was with your work with something as simple as a hardware store mini MIG machine when I noticed the photos were named "TIG Stuff".

I named them that to be sly...
That's not my work. A friend of mine does that stuff. He is crazy talented with welders, build trophy truck and custom cages, etc. He's ZTfab in this thread. http://weldingweb.com/showthread.php?t=30845
He's one of the most helpful guys and has held welding seminars at his shops, free, to help out us guys that don't do it for a living. MIG, TIG whatever you wanted to learn or brush up on, all equipment was available for use.
He did all of the work in the pics with either a Lincoln 110v SP135 or his PowerMig200. I thought it was only the small box.
John, this is what good Mig looks like when you get wire speed, voltage, technique, fitment in sync.

Well that's just BS. Spatter is a result of or combination of the gas used, the wire type, the welder setting and the cleanliness of the base metal. Not to mention that an anti-spatter spray will also do the trick. I do a lot of mig with no or very little spatter. I'd rather spend the few extra bucks on a mixed gas than the extra time cleaning spatter.
As for those photos, a proper tig weld is easily identified by a concave or flat puddle whereas a mig weld will most often be convex. As for the "stack of dimes" look, yeah its pretty but its no better than a continuous mig bead.

Well I do use 75/25, anti-splatter spray and asbestos blankets when needed and only do the tight little circles for the Stacked Dimes look when its highly visible, like under the hood or dash areas.  If I want the quality of all those factory welds on our K-frames then yes I can turn my welder up to D heat range and 8 wire speed and just lay a weld on and it will hold fine.  Going fast puts less heat in the area too. Well I hope we have answered the OP's question.

You guys are great! That's the best welding advice I have got so far. Thanks.
And you all convinced me to trash my basic helmet for an Adjustable Shade Auto-Darkening Welding Helmet.
Again. MUCH thanks. 
I use a $50 harbor freight auto darkening helmet with adjustable lens, works pretty good for the price.

Funny you mention that about auto darkening helmets, I find the auto darkening feature absolutely useless since it doesn't go light enough to really see through...
I bought this auto-darkening welding helmet for $140 and I'm very happy with it. It's not adjustable, but it's perfect for MIG welding. And it lets enough light in to see what your doing before you start welding. I'm really happy with. And its made in America, which was a key selling point for me.
