I still have not tried it after the last response. My Lincohn 100 has 3 settings for heat: B, C, and D I think. And wire speed from 1 to 10 (or 9). I tried all heat settings. On wire speed, I tried between 4 to 7. On welding thin metal, maybe 1/16", I felt that the wire was moving faster than my hands. I usually use flux wire 0.035.
When I pull the trigger without welding (without touching the metal), I see/feel that the wire coming smooth.
Sometimes I got good bacon frying sound and laying dimes nicely, but rare.
