I'm so glad you understand there is nothing difficult or technical about welding, or weld testing.
You literally do not know enough about it, to understand that you know nothing about it.
The destructive weld test has more to do with bending over a radius and stressing the weld by forcing it to curve, putting half in compression and half in tension. It's has very little to do with ram force.
Fwiw, I rarely see over 800 psi developed pressure to the IIRC, 2" diameter hydraulic ram in out tester.
Typical pressure are 500-700 psi bending 1.5" wide 3/8 A36. Do the math and get your tonnage required.
I have no problem with your machine or wire.
I have no faith in your competency in executing a sound weld.
The pictures I've seen looked like the metal still had not been prepped.
Also appeared to be torch cut with no cleanup. Welding material that has been flame cut, with no cleanup can be tricky as the cut surface has been subjected to rapid oxidation and is no longer the same composition as the base metal, usually resulting in weld porosity due to contamination by slag.
As well for your machine, you should be multipass welding nearly everything .188" and thicker, depending on the joint.
I see single pass welds with no post cleanup and inspection.
