This is my first post. I am new to welding generally and very new to aluminum. My aluminum welds are just absolutely horrendous and I’m not exactly sure what I’m doing wrong. Would love to get some advice!
I’m using a pretty cheap welder that I bought off Amazon which is probably part of the problem. But it I’m also imagining that my voltage and speed settings must be really off as well. I’m using argon as the shielding gas.
I was using the aluminum spool that came w/ the Lotos (and was unmarked in terms of alloy). Right after I posted this and switched to ER4043, and it seems to be much better, although still pretty horrendous compared what I'm sure any of you could do!
Your WFS is terribly low. You need a lot of amperage for aluminum due to spray transfer method required. I would simply max both out and then dial it down from there if you are able to obtain spray transfer...but before you do that......
It's a MIG box, therefore DCEP. A more important question is what GAS are you running? Many people use 75/25 with their MIG machine which is correct for steel but not for aluminum. Aluminum requires 100% Argon.

Some MIG boxes can have the polarity switched internally, so it's a fair question to ask.
