What do you do when it is Saturday afternoon the local hardware store closed at noon and you are right in the middle of wanting to run some 1" emt conduit when you run out of box connectors?
Well you can drop everything and drive 75 miles 1 way to the next open store then by the time you get back you are either out of time or out of the mood plus you spent $20.00 on diesel just for half a dozen connectors.
Or you do like I did you go to your pile of usable stock and someday materials dig out several cut off pieces of 1" pipe that already had threads on one end cut off what you need and bore them half way through to make your own box to EMT connectors
1" pipe is the same thing as what is called 1" ridged conduit. the threads are the same as well. you just need to bore it out large enough for the EMT to slip in this works for 1/2, 3/4, 1 1/4" 1 1/2" 2" and so on Only when getting above 1 1/2" the shell thickness may be thinner. I haven't ever had the occasion to try anything larger than 2"
My fit was almost a tap in fit and the conduit is going between 2 boxes so I really didn't need the locking screw but put in in anyway by making a weld glob then drilling and taping to 10-24

I just looked up your wire. Your using a wire feeder! I’m an old fashioned stick man myself. My dad was born in 28 and was a welder for 70yrs. He loved to torch weld. Even in a world of easier options he loved the feel of that torch in his hand. His welds would look like tig. He was a master at his trade. He taught me to stick weld first and the others came later. I always came back to the sticks. I loved what you could accomplish with them. You don’t have to worry about the air around you moving. Your base metal can be a little bit rusty or greasy. Not to mention super portable. No torch to over heat. I think it’s a lot easier to weld heavy trailer hitches and the like with stick. A mig machine big enough to weld 1in plate is not cheap. A used 300amp Lincoln Tombstone can be had for 200 bucks these days.

But ill regardless a tiny glob will never be anything more than a simple built up area to thicken for use as a means to hold enough threads to hold a screw LOL
In welding terms there are processes called short arc globular transfer Spray arc etc.
Most wire feed welders are used in the globular transfer mode. Short arc is usually only when welding real thin material at very low amperage with very small wire like .023" Spray arc is really hot and used only with certain shielding gasses such as trymix or 98% AR & 2% ox. this is done normally on tubing where the parent metal is thick enough to transfer the heat away from the weld area while the wire is almost being vaporized while being applied. the sound of the welding process will be a whistling sound.
globular transfer will if done correctly sound like the steady sizzle of frying bacon

I like the .045"duel shield flux core wire as my go to filler material for many reasons 1 I can adjust down to make welds on thin materials that would be difficult to do even with the McKay 1/16" rods or spin the setting up to lay down more filler than can be done with a 3/16"
I own several machines such as a 400 amp gasoline drive Miller 2 Miller 250 amp gas drives a Hobart 450 amp mig welder Miller 210 Amp mig 300 Amp Airco DC power supply a Lincoln 250 AC stick welder a 130 amp Hobart mig another little 130 amp mig that I can't even pronounce the name of and my latest addition is a 500 amp National AC/DC tig machine that I can't use yet because I haven't had 3 ph installed and to try and run it on a rotary phase converter would send the electric meter into orbit.I'me sure it would make my electric bill jump a 100 bucks every time I turned it on I think I may have at least 5 more welding machines that I have forgotten their names and sizes.
Like having 5 lathes 7 band saws 3 mills and 4 drill presses how many machines can 1 old man use at the same time is the question my wife always asks me.
I tell her it is not a matter of how many I use it is how well diversified and how wide of range of machines I have at my beckoned call. if I decide I have the need
