Mig Flux Welder

Is that welder decent for a beginner? I would mostly do aluminum and don't want the gas.

Can you get aluminum welding wire with a flux coating?

You need gas to be able to weld aluminim and both are capable if you purchase a regulator and gas which is not included.
You would also need a cable liner as the aluminum wire is soft and will bind on the rough metal sleeve.

The Princess Auto one has a higher duty cycle at 20%@105 amps.....the Can Tire one is 20%@80 amps.
I also think you would get better support at Princess Auto where you will surely need accessories and spare parts.

You should know that mig is not that great for aluminum welding even though you can get the wire and gas to do so.
You might want to reconsider and get a TIG welder instead which is the commonly accepted way to weld aluminum.

I agree with Greg. If you want to weld aluminum you should be looking at a TIG.

I would also suggest taking a welding class. Aluminum is not the easiest to weld and could lead to frustration if trying to learn welding on your own.

I guess I'm gonna have to wait for a deal. Most "cheap" store don't carry TG welders not at Canadian Tire anyways. AS for Princess Auto they carry Lincoln but they are over $500. I basically would use it maybe once or twice a month my next project is to build an aluminum box (no front) so I guess for the seams I can use some angle aluminum with rivets!!!

I am not sure if this would work for your application but check out Alumaloy. It appears to be designed for repairs but it might work for you.

Also look at aluminum brazing rods. Kind of old school but much cheaper than a TIG

At the risk of dredging up an older thread: there are no flux core wirefeed solutions for aluminum welding. TIG is ideal, but there are gas-shielded MIG solutions too: you'd need 100% pure argon shielding gas and a separate MIG gun. The separate MIG gun holds the aluminum wire spool because the wire is too soft to travel from inside the welder, which pushes wire a fairly long distance through the cable and out the gun. Aluminum stick electrodes are available, but you'd need a DC welder and they cost about $25 per pound last time I checked; they would work best on a "field repair" basis and require some practice to get proficient.
