Will a flux welder weld aluminum?

Could you elaborate on the capabilities of a flux welder when it comes to welding aluminum? I've heard that aluminum welding can be challenging due to its high thermal conductivity and oxide layer. Does a flux welder have the necessary features to overcome these obstacles? Are there specific techniques or settings required to ensure a successful weld on aluminum? Additionally, are there any limitations to using a flux welder for aluminum welding, and if so, what are they? I'd appreciate your insights into this matter.
