What did I do wrong???

For Lincolns this is false! I have a Lincoln Weld pak 100 and a Lincoln Pro-Mig 180 and I have never set the wire speed above 4 on either unit for flux core welding even at the highest amp setting D or E. I have no idea why there is such a fast speed on such a low amperage unit . The .030 flux core certainly behaves better for me in the smaller unit.

I think it's for feeding wire after changing a roll, not for welding.

If you are using argon and .023, it would probably not be too fast...A lot of the flux core units are using the same components as the gas units. Flux core small welders are mostly for marketing...to offer a price point. Then you can convert them over into gas, another tool used for marketing...for an additional price. Most of them are PRE wired for this and are simply the same welder with out the solenoid plumbed in.

Flux core uses straight polarity, reducing the melt off speed as well. Reverse the polarity for argon/co2, you will burn the wire off at a much faster rate.

I am surprised that no one has recommended preheating the metal prior to starting. With those low power wire feeders, it is should be taken as a requirement on anything thicker than 1/8". It will allow you to run fewer amps (slower wire speed) and still make it penetrate and make a more uniform appearance.

Preheating only helps with the controlling of stress cracks typically done on thicker pieces . Even if you preheat you should always run the same amps as you would as if you did not preheat to ensure proper penetration.

I just found this site and it gives a video version of all these guys are saying. I've been welding for years (NOT saying I've been a welder for years), but sometimes mine looks like yours. I took a welding calss (stick) about 30 years ago, so I am learning as much here as you. Keep at it like they say. Everyonce in a while I turn out some pretty welds that are good welds, but not very consisitantly, unfortunately. But I keep trying.

Just like riding and working on the tractor, I learn more each time I do it. Plus this site (Tractorbynet) helps a HUGE amount, on both counts.
