Welder/Plasma supply wireing, need homework graded

I agree with Dale about it making sense to use the bigger wire and the economics and the performance not affected and maybe even improved. If he would have said,,, you must or else he would have got an argument of sorts and in some cases its suggested not to, doesnt matter on his welder, doesnt hurt a thing and he seems to have a grasp he is plugging something with a 14 cord in to it anyway.
I actually copie more old timers now than when I started and thought I knew. First welder outlet I install had 3 conductor and was 6, I eventually put a panel on it which worked but I hav essentually wired wrong in some sense and then I go look at my neighbor, a true master holds every license can be had in this and his welder outlet is the same cable, still there, a number 10. Been there 40 years now and this is a guy who knows and could have any wire or pipe they ever invent for free and his outlet is a simple cable.
We know each other a long time, I study under him a little but he says,,, I know a hundred electricians and you are someone I would let wire my house. Its not cause I am a genius but because I will slow or stop to fix something not right. Doesnt mean I wont hook up something with a range plug but I know the difference and knows I dont hide mistakes or dont have a fuggit no one will know attitude. He also know if I dont fully understand I would ask why.
But this,,, its obvious some dont know and they got it,,,, I know and you dont and I aint gonna learn position. Whole reason I started code stufdy, so many quoting it didnt know squat I had to find out. Bought the book, followed code forum with the book. There were a couple eld timers were frustrated but it took a while for it to make some sense and I still dont know all of it, really focused on the stuff I used.

I am not sure how they deal with licenses in other states. Here contractor is slightly different and a guy could get it if he employed a master. But I am suspect that it really doesnt involve a masters test or maybe even a journeymans. But the fact that the first guy comes on and describes his wire that has a problem then the next jumps on it with,,,, thats what I did has me wondering wtf.
Gotta love the logic, picks a part of the code say you are allowed to do this and tries to make an interpretation says it isnt then does in stall where they expressly say,,, do not do this but its ok cause,,, I did it that way. Thats my whole point with this.

I wish I had a prize for the answer for this but an "attaboy " might have to do.
What is the correct term for he white wire in a 120V circuit?

As for locals, they rarely fool with amendments, there is a lot of lore about it. Some have adopted the IBC (is that right) which says, only 1 240V outlet to a circuit above 20A for residential. When internet exploded there was a quite a bit of pondering about 630 and several suggestions about requiring a 8 pipe or 6 cable for 6-50 to residential, there was a suggestion it be labled for welder use only, which is not in the code, its not a bad idea, neither is 6 wire really due to the fact you never know when a booger be wired on but what the ultimate move was,,,, nothing. According to one on the board was,,, because we got a bunch of internet diy types dont understand it is not reason to change. It would be different if it was a problem contributing to fires which it hasnt been. They are a pretty serious bunch, it wouldnt have taken many incidents for it to be looked at harder and maybe sometime they will.

The reason the IBC did this wasn't cause they worried about overloading the wire but expressly due to the questions at the start of this thread
So many assume all "220" the same and they were changing the ends and hooking equipment on circuits with improper ocpd. Sposed to have 20 or 30 and they hooking it to 50 often with "creative" adapters
As best I recall there is only 1 legal 50 to 30 adapter and that is 14/50 to TT30.
Thebteason they don't allow 30A on 120 isn't primarily due to wire heating but that all the shat that comes 15A cord and plug is designed to be connected to 20A max breaker.

A guy asked me how I'd add a 100a panel to a barn and bury 300' of wire to it. (still no 240v used 25 yrs later) I suggested he plan his loads/outlets/breakers, refer to NEC for wire size/ampacity, and check state/local codes for burying depth, wire type, conduit or not, etc.

For mere suggestions I got a 25 min throttling for writing codes that were never considered, much less my doing, before I wished him luck. He ok'd a 14 ga line to a Grandson's garage & 100a sub-panel with four 20s breakers on four 14ga circuits therein.

Everybody has their own opinion. Sometimes it's just fun hearing what folks add to a conversation.

btw, LouNY and Dale think like I do no matter what others say. Doesn't mean we're always right, but we're in sync for the same reasons.

Neutral.... But from a non certified electricians point of view.... But could it not also be a neutral wire in a 240V circuit (unless taped)? ... And yes I know it's understood the white wire is a "load" conductor in a three wire 240V circuit (maybe technically it should be taped red, but again maybe not) ....

I also think what set me on edge is the phrasing of 12/2 or 14/2 of maybe 6/2 or 8/2 for describing "Romex"... I hark back to old days when XX/2 was literally 2 conductors and no ground.... Would really like it if people would use "12/2 W Ground" and the emphasis on "With Ground".... I know new modern "cable" is generally equipped with bare ground wire.... But the old school learning from when I was a lad still stays with me..... And for some 240V circuits (that also use 120V) X/3 wire w ground (ie 4 conductors).....

Dale,,, I gotta let the question run farther yet. The wire doesnt know if you are certified or not.

Breakout boxes forever, unless you got busduct.
I got both.
