anybody have some tips on 1/4" thick aluminum? Been messing around with some outside corners and butt joints. I can't get the weld to hold by what I mean I would but the piece in a vice and be able to break the joint the weld cracks right in the middle. running about 200-215 amps getting a good puddle while welding and looks good when done but when tested it breaks. using 3/32 4043 and 3/32 tungsten on the dynasty 280

4043 rod is the problem. Found it out doing test welds for a project in the shop with aluminum gmaw switched to 5356 and it held waaay better.
Give that a go. I'm sure 4043 welded on both sides would hold but I don't think it's made for that kind of force application.
I may be wrong but that's my experience with it.

The pieces were small. 5"X1" 1/4" thick. Took a few hits with the hamer I know the heat build up is a lot on the small pieces it was just some scrap I had laying around. If I put more heat into it would become a melted mess. Had the machine at 150 herz then tried it around 230. With 68% balence I will try some 5356
Should we assume 6061.
Stone knives and bearskins.....and a NEW EVERLAST 164SI !!!
That's my newly shared work welder.
At home I got a Power Tig 185 DV. Nice, but no plasma cutting... Nice tight arc after a second.

Nice looking weld first off.
In my opinion, when you say it breaks in the middle of the weld, that's normal for what you have pictured.
The weld isn't fully done yet. The corner is still flat and would break in the middle.
If you imagine the corner of angle material you'll see that this weld still needs more reinforcement. Unless you like this look, then you are done
