Welding different thicknesses of metal

I had difficulty welding two different thicknesses of metal together, I was blowing through the thinner metal, So I ran the arc along the thicker metal until it ran and then ran beads until the hot metal touched the thinner metal and made a final pass to stick the thinner metal to the thicker without heating it so much I blew through.


another tip for welding metals of different thickness is to preheat the thick side so amperage can be turned down to prevent melting away thinner member.
