1.) Providing the forum with the specific Al alloy would help in your selection of filler metals.
2.) Try adding helium to your shielding, it will increase arc voltage and heat input to your Al casting. Try also preheating (not excessively) your part. How is the part being prepared prior to welding? What process are you using?
3.) Finally, what is it specifically the material "...dosen't like..."? Is it difficult to adhere filler metal to, contamination, etc.
