Sure. Fcaw is like stick welding. It's always better penetrayion than mig per power level. But any issue you have with a bead and it's, clean all the crap off maybe grind it back, bla bla bla. Never gonna do thin sheet metal nice. I did my dual rear caliper handbrake setup with a 110v mig on probably 1/4" thick forged steel. Just set it up right and gouged it out for full penetration.
