I forgot Runs, your Bonifide, but I don't think in welding. Maybe the lumps in the welds are from running it too cold like your setting for 5/32.

That weld is 4 welds.
2 tacks, and then two beads running along the lug sides.
Done with a mig gun on a jig. Mild steel wire.

Since the material below the weld is very thin, the gun is aimed at the side of the lug to put enough heat on the lug for fusion, but not burn through the tubes. More of an overlap onto the tubes as opposed to a full wet out situation. I don't see a ribbon of silver next to the bead.
An inch on each side of that lug would give substantial purchase. Like in the thousands of pounds to tear it loose. Taking a section of barrel with it.
The little dimple at the ends of the welds with the spot in the center is a dead give away for a shop wire weld where the operator didn't let the gun cool the weld after releasing the trigger. You have to let the gas patch cool the puddle or it dimples.
I'm guessing there was a time/production constraint regarding welding model 24 barrel lugs.
I think Mr. Fox misspoke. 5/32 takes at least 150 amps to run, and even on my best days, I would never weld a thin tube with 5/32. I hope he meant 3/32, and about 55-60 amps.

At Ford Rouge Steel (Severstal) I once poured 50lbs of 5/32 7018 rod (with flux, almost 3/8" dia)into the sides of a run-off trough in 1 shift. All vertical stringers. 9 stringers deep. 5/32 typically runs 3 rod widths in puddle, so a 3/8 to 1/2 inch wide puddle is typical. As fast as I could run it (never lifting my hood between rods changes), the guys running LN-25's with innershield wire walked away from me.

The gun is just a lowly winchester model 24 in 16 gauge.

You both don't read, and know welding-for sour owl shit, dude- using 1 amp as a ROT (rule of Thumb) you would run 1/8" = .125 at 125 amps- varies from welding machine and also the AWS code for the rod in 1/8th- 7018, a down-hand position only high iron powder fluxed rod- runs and lays down a bead best on AC- whereas Lincoln's iconic 5P -- 6010 pipe rod, will only run on DC reverse polarity, and as it has a thinner flux coating, about 112- to 115amps, depending on what position you are running the weld pass(es)- If you only have a Lincoln 180 or the later 220 Amp AC only transformer "buzz box", use Lincoln 6011- basically 5P but with a stabilized flux for AC current- If, as my son-in-law and I have in our machine-welding shop, you have a newer series Lincoln with the rectifier and both AC, and DC straight and reverse polarity selector feature, you can run any rod up to about 3/16" dia-- 1/4" and up- like the real heavy deposition 7018 rods and also 1/4 8018-90-18, etc (Lo-Hu Code rods) you need a 60 to 100% duty cycle 220 or 440 single or three phase power input industrial grade welder that has a minimum of 300 amp output rating--I do use some 5/32" and you will see that as a general ROT- 130 to 135 amps-

I spent my whole working life after my stint in the USMC welding to various codes-don't come to me with your cheap shit comments, I've pissed away more knowledge about welding both ferrous and non-ferrous metals in all positions with SMAW, MIG in mainly 1G, some 2G and 3G positions, and TIG- 90% of that on the bench, so 1G position-- And the welds show evidence undercut- a dipshit like you probably thinks that means a loaf of French bread cut from the bottom side first- and the weld beads are non "lumps"-- they are crowned- a slightly longer arc gap when running weld passes in the I G position is the main cause, also running rods like 7024 on the "cold" side of the possible amperage range- get it???

"only know the term bonafide from my father's usage. When he said "so and so is bonafide", that was his shorthand version of saying "bonafide [censored]." Legit. I wouldn't want to put those words in JDW's mouth. I'm sure he meant something else."

I had used this term which was taken from the movie "On Brother Where Art Thou". Where Clooney's wife said her suitor was Bona Fide.
"Bona fide pronounced [ boh-nuh fahy-d] means to be presented in good faith; without deception or" ...............which we know that most times Runs with the mouth is not.
