Weld Al with a stick welder

[petersenj20]

I checked out a Arc welding book at the library and it has a technique for welding Al with a stick. I still have to buy the rods but can I be successful with an AC machine. It gives the directions (Don't weave the electrode, scratch to start, and keep a short arc) but says will work best with a DC machine. Does that eliminate my machine or just not as good welds. I am just talking about learning here, not welding on a trailer or anything important.

Yes you need a DC machine. I welded alot with stick and its fine for castings but sucks for pretty much everything else you want to look nice. Unless you just give some little tacks...Bob

I've done it to practice and be ready for an emergency job with it. I've not tried it on AC, but with as difficult as it is, DCEP was tough enough.

I would never recommend or use the SMAW process for welding aluminum on purpose. But I keep the rods around, just in case all else fails on something.

I threw all my aluminum SMAW rods in the garbage and I hope someone I don't like finds them.

I nearly bought the electrodes but chickened-out when quoted $19 /lb. I have never welded Al with any weldor. I just wanted to try something new. I assume mig is the medium of choice? Thanks.

Pulsed mig [thin], or tig is best for aluminum. I use tig on everything thin and pulsed mig on thicker stuff. I didn't have much luck with stick for aluminum. Somebody must or they wouldn't sell them.
