Flux core aluminum wire

[FX4STROKER]

Hey everybody got a few questions. Ive got a miller bobcat arc welder and have some aluminum rods. has anyone tried these aluminum rods for a arc welder. I also have a little 120 flux core gasles wire welder. Does anyone have any sugestions about either. thanks

if you are able to put gas(100% argon) on your wire fed that would be the cleanest weld out of the both, also many suggest to run a new lead and trigger just for the aluminium

I have used the aluminum rods before......not a pretty weld but it will hold.

You need to practice on some scrap pieces first.....nothing like welding steel.


Good luck with this endevor...just make sure you practice first.

There is thiso other stuff out there its like brazing rods for alluminum. The nice thing is all you need is a propane torch. i used that stuff with good success. i welded up a case for my buddys dirt bike saving him 600$ 3 years ago and it still holds up fine.
There is a place by my house that sells it its 8 rods for 12$.
if youre gonna weld steel you should add gas to the welder you have. i have a cheapie welder also well it was 200$ so it wasnt cheap cheap but I added gas and its a WORLD of difference in welding as far as finish. Way cleaner welds

Make sure they will even work on your welder. I bought some once and they were AC and I had a DC welder or vice versa...

the gun for aluminum on a mig welder is not cheap either, thats the only thing holding me back from aluminum...

If you are going to weld aluminum, ONLY use AC! It will work on DC (straight or reverse), but use AC unless it's an emergency. And make sure you brush the area down good with a stainless steel wire brush...make sure it's stainless steel, because a regular steel wire brush may contaminate the surface.

Not cheap at all. Miller is good machine though. Get Gas, (Argon preferably as previously stated) And practice, practice, practice on scrap. You have to "roll" a lot faster when welding aluminum as compared to steel.
