Stick welding aluminum

   / Stick welding aluminum #11  
Couple things I learned. Just before welding use a stainless steel wire brush on the weld zone. And a little preheat helps too.

It's interesting you have it labeled 0.0 arc force. This was the first time I was wondering if I could have benefited from adjustable arc force.

Personally I think a spool gun does a much better job.

I'm thinking the OP was just stating that for a small aluminum repair, aluminum stick is a cheap good fix. As far as aluminum mig welding goes, everybody that can mig weld steel, can mig weld aluminum, and it does come out a lot better, but to stick weld aluminum, you have to be good at stick welding, and then it's a challenge. Then you have the cost set up for aluminum mig welding.

I've welded a small aluminum project before with 1/8 stick on 1/4" thick angle bar, worked ok I thought, the welds was strong and lasted, I think I set my DC welder on DC straight, on the stop and starts, I cut the end of the rod for a better arc re-start.

I keep my stainless wire brush in the consumable drawer under my Lincoln TIG machine. Always handy.Right with my TIG finger and doeskin gloves.

This was playing with the pulse when I first got my Lincoln V350-Pro welder.

I've done some repair work with stick before. Actually, the first time I did it I was surprised how well it worked and how strong it turned out. However, unless it is something remote in the field, my spoolgun is the go to and that's after a good brushing with my stainless steel wire brush that hangs on the wall dedicated for aluminum.

I have used them in the past.
The learning curve is straight up!
KEEP the rods in a container! If you lay the rods down they will become wet in minutes!

That's no joke. I did a repair and left the remaining rods in the plastic container they came in. Next morning I had some overpriced short pieces of aluminum wire.
