I know this isn't Vett stuff BUT we were on the subject....
You should have both a wire speed (may be called amperage) and voltage control. Turn up the volts and turn down the wire speed.

No, you shouldn't need gas with most types of fluxcore wires. Make sure you don't have one of the types that does require gas.
If the feed is turned all the way down, that wire should be moving really slow. If it's not, you have a problem with the machine.

You have the wire speed way too low, the slag is because the wire shorts (short circuit transfer) and is burned away all the way to the tip and then new wire comes out, arcs again, burns away..and so on. Basically all you're doing is dropping ugly blobs of molten wire on and not putting any heat in the work piece, weld hot and turn up the wire speed. It should make a nice sizzling sound, if you turn up the volts (heat) real high and the wire speed you will go into spray transfer mode, which makes an electrical sound, very distinctive.
The wire speed is the amperage control on the MIG welder, the higher the wire speed the higher the amperage.
Don't be afraid to weld hot. Also make sure you V groove the stuff you want to join for full penetration.

Good point...I just continued to turn the feed down to the last (slowest) postion. Teh wire was always sticken to the end of the feed nozzle, I'll try the reverse and see if that makes the difference your talking about - THANKS!

I have a 135 Lincoln Mig and have gotten to where I can do decent welds, all self taught. I have always needed a torch setup, so I just bought one of these after seeing them in the new Eastwood catalog. I am looking forward to using it to do some tig type stuff. You can get them on eBay for about $150 less than the Eastwood price.

Watch the videos on the streaming video page, if it works at all like the video for cutting sheet metal and steel and welding, it is the best all around garage tool ever.
I will report back more once I get a chance to try mine out.
