Ditch a 1 8 inch tungsten electrode for something much smaller like 1 16 inch tungsten.
How to weld thin sheet metal.
If you are welding thin sheets ignore the 1 8 inch tungsten electrode.
The wires in fcaw are direct current electrode negative.
While wire feed welding sheet metal go for short bursts of welding instead of a going on a long bead.
Try going for a wire of 023 inches when welding sheet metal.
Forget the larger 1 8 inch tungsten electrode and use a smaller one.
Only pause at the puddle and then move back to establish a puddle in the crater.
I use 6010 6011 for thin sheet metal.
The way around this is to weld in short pulses allowing a second or less between pulses for the steel to cool down.

In the video i ve left about a second between pulses.
For you first option use the ceriated tungsten followed by the thoriated tungsten.
