AC Aluminum help

[christian]

Well,

There may be some other issue.

I'd check the torch collet seating. And ensure that the tungsten isn't fouled.

Upload a pic of the torch head all ready to go.

And upload a pic of those "tiny pock marks" too, please.

Also, what color tungsten are you using for aluminum? Green is no good for an inverter on AC.

Oh Lord I bought the green. Could it be that easy?
I'm using red on steel, is that right?
I will go fish the parts out of the bin.
Tungsten is not fouled, I have learned better after doing that the first 1000 times on steel lol.

Yeah,

I've never used Green on AC, but that could be your presenting problem, as it's a well-known no-go.

Red will work on AC, and is fine for DC.

Blue is good on DC and AC, too.

Thank you for your help. Fabricator guy at work told me to buy the green. For as a good as a welder he is, probably not familiar with inverter machines as he has been doing this for a very long time..... you get my meaning lol.
So, preferred tungsten for steel, stainless steel, and aluminum? I don't care if there's three different ones I need to get just want to do it right.
Thank you

Just called another guy, he said use blue for everything with my machine....

Yeah,

Blue is probably a best "one color" tungsten solution that's reasonably priced.

But, Red may actually be a tad better on steels, while Blue may be a tad better than Red on aluminum.

Otherwise, I most often use a "Cream" color TriMix for both. They cost more, as they're German produced. But they're undoubtedly the best, and I don't weld a whole bunch, so they're easily affordable.

So, Cream, Blue, or Red are all a good one-color solution, and in that order.

Make sure you have your torch in the negative, not the positive. Set balance for 30, and set frequency for about 90-100.
