I have some sheet steel 1000 x 500 x 1 that has been painted and is quite rusted, I want to weld a barrier of 16mm RHS around the edges to for a barrier. I have ground all the rust and paint from the sheets. I tried a test and the weld does not seem to be sticking and seems to be in small balls along the join.

I am using a CIG Arc Inverter 140 amp welder.

Are my rods too old?
Does the sheets need to be cleaned with something else?
In short, what am I doing wrong?

Thanks
