309l is ideal to join your stainless steel to mild steel because this welding wire is made to weld both metals. After you are finished welding make sure to clean up the slag with a brush made of stainless steel. Your wire feed speed also plays a huge role in welding stainless steel with normal mig wire. But for much thicker stainless steel a faster wire feed speed is required to create a larger welding pool.

To stick weld stainless steel make sure to set amperage low enough so that you get a smooth arc from start to finish. These include the mechanical properties chemistry and ability to resist corrosion as taking the right decision can prevent any trouble that might creep in overtime. Focus on the properties of the metals you intend to weld. Firstly before you weld stainless steel to mild steel you need to consider the properties both metals have.

If you re welding mild steel it s more comfortable to manage as you d use a lower wire feed speed. Browse suggested weld parameter settings for stick welding.
