creating a 220V extension cord
I am currently trying to make a 220V extension cord for a welder with an interesting plug and have an odd question. I am planning on having the male end be a 6 foot dryer cable (because I only have a dryer 220 outlet in my house) and have the female end be a NEMA L620 outlet. I have 12 AWG cable for the middle with green, white, and black wire colors. the male end is ready, but I do not know whether the white "neutral" wire should go to the X or the Y slot. The plug on the welder is labeled with a W where the X slot is on the outlet.

Stop
You don't seem to have enough knowlegde to continue and are going to hurt yourself and/or others.
Go by the proper size wire for the "middle"
Here is my suggestion. Make two cords. The longer one will be a proper cord for your welder...and a short "cheater cord" to go from the dryer plug to welder plug.
Please make sure ALL wire is able to handle the supply aperage!!!

Is there any reason why can't you just run new welder circuit ??
Oh by the way Ukraine1.,,
This set up is NOT allowed for safety reason the 12 gauge cable is way too small for welder useage.
For common stick arc welder they need at least #8 gauge or larger conductor to use properly. { The NEC have specal code for this and it will be diffrent than the genral circuits }
For other type of welder please let us know due there are quite few diffrent type of welder on market like Arc welder . MIG welder, TIG welder etc
Get the model number of that welder and the ampcapcity from the nameplate info like voltage , amp that two circital part { with welder please let us know the duty cycle as well it will affect the wire size as well }
Merci,Marc

I made an extension cord for my arc welder. I used #8 wire with a stove plug on 1 end and a stove recepticle on the other. I don't use it often but it works well when I need it.
You would use dryer plug/ends if using a 30 amp circuit.

I agree with the warnings posted above. Electric arc welders have specialized power supply circuits, depending on the complete nameplate data (amps, duty-cycle, etc.).
