i'am, been doing so for close to 20 years now. have several pipe certs, which also carry over to plate.
your machine is set too "cold". if you used the chart that is likely in or on it, it's close but still cold. how much color is on the back side of the plate behind the blocks?
if you put a bevel on that, it wasn't much of one. that weld is what, a quarter inch or so? actually looking again, right at the corner i can see the little bevel you had. that falls under, under cut. something that small, with a cold machine can do more harm than good. it's very likely that the very bottom of the bevel is now a void the length of the block.
the better way to mount that, instead of just setting it on the plate. would have been to cut a hole out the size as the block, and set the block through the plate, in order to weld both the front and the back side.
the third "tack" down from the top, you can see a dimple in the center of it, compare that to the tack on the joint visible in the back ground, same dimple. thats from the pubble cooling off. there is no need to "whip" hard wire on a horiz run, just push it. since the machine was cold, when you whipped(way too far i might add. you don't even throw 5p that far), the puddle cooled off, so while you may not have let off the trigger, the steel says otherwise., but more importantly, will think otherwise. it looks like there might even be alittle cold lap going on there.
like i said, i wasn't calling it bad, just what i saw. i doubt it will come off.....you asked for this post.
