The last weld, D looks good!
Try to listen to the sound of the "weld flame", it should sound almost like the sound you hear when you are frying pork. An intense popping sound. If you have a long period between each "pop" you have either too low current or too high wire feed (or a combination of both). If you do not hear any "popping" sound but more like a "hissing" sound you have too high current for your set wire feed. Increase the wire feed or lower the current.

Good luck!!

Eastwood has a 30 minute video on MIG welding. It has a sound track. Every th
ng you said is on their video. I'll later try to get the website address. The sound track is important. In extreme cases, you can tell by the sound that you're not correct. ..The Eastwood video describes a successful MIG welding as sounding like bacon frying.

I'd really like to buy a welder. Problem is I don't have anything to weld!!!!!!

This is a 31 minute video for beginning welders from Eastwood. The machine they're using is a Eastwood MIG 175. It has audio so you can hear the torch and can notice the difference between having bad settings; not enough heat, too much, not enough gas, etc.

Well I finally got enough together that I broke out the little 110V Lincoln. I purchased some .035 flux core. Figured out the chart, duh......... Reversed polarity and holy mother of.....? Totally changed the characteristics of my machine. HEAT! Where I was getting blobs sitting on the base metal because of no heat. I now get a cherry heat, I can probably burn a hole right thru 1/8 plate. In fact that's what I had happen on 1/16. Wakey wakey little Lincoln! WOW! No spatter either.

Thanks for the suggestions guys!
