A 3D printer for printing with welding wire

I tried out spraying CO2 and Argon Gas on the melted metal while printing, but unfortunately I couldn't see any difference in print quality. Maybe I did something wrong or it has something to do with using resistance welding instead of arc welding. Will maybe test it again in the future...

I couldn't notice any difference, but maybe I did it wrong. I just sprayed it per hand on the melted wire. Maybe the gas has to flow throug a shielding gas nozzle to shield the melted metal as intended, but that would need a redesign of the toolhead. I think I will repeat the test with a shielding gas nozzle when the wire feeder works reliable.

Was metal finish better or did it still looked oxidised?
