I am a newbe welder. Trying to weld in floor panels with HF beginner welder. Using .030 wire with internal flux. New panel is thicker than OEM floor. (Go figure!) Using low setting MIN with 1.5 speed. Both surfaces clean and even. Lots of splatter. OEM floor burns thru. Tried new clean piece of weldable sheet metal from Lowe's. Just trying to lay a bead. Nothing but splatter and holes. Help a newbe welder, please.
