You will not be able to weld aluminum with a flux core only welder.
Mig welding aluminum without gas.
A normal contact may well jam the aluminum wire.
Because aluminum is a non ferrous metal it requires a 100 percent argon shielding gas.
You can find out why here.
You sure want to avoid circumstances like the ones i mentioned above.
And if you have bought or have loaned a true mig welder.

05 08 19metal inert gas mig welding uses a consumable wire electrode and shielding gas which is continuously fed through a welding gun.
What process should you use.
When welding keep the proper aluminum filler electrode or rod free of contaminants and melt it with the base material to create a constant welding puddle.
Flow rates of 20 to 30 cubic feet per hour are recommended.
Choosing your contact tip.
Aluminum as it heats up expands.
However the first thing to clarify about the no gas mig welders is that there are no so called gasless welders as the gas is always used to protect.
