My landlord put in a couple 50 amp 14-50R's for his sons' Teslas to charge at night. He said I could plug into them to weld and I want to make sure I'm making a proper extension cord. I have a 30 amp Eastwood MIG 180 and am only working with up to 1/4" material with 2"-6" beads with a lot of prep / propping myself between each bead usually.

I'd like to convert a 10 AWG 5-15 100 ft cord I have to a 14-50P on one end and a 6-50R to go between the house and my welder. Input on my welder is 240 VAC; 29.6 AMP and 120 VAC; 24 AMP.

I couldn't find much info on how to do this but on weldingweb.com this post described the opposite of what I want to do (6-50p to 14-50r vs what I want) but I think it would be the same just opposite on the R and P:

"I relive I'm dredging an older thread but I have a question on this since it didn't seem he got his final answer.

I have a similar issue with my welder having a 6-50p so I am making a conversion cord from 10/3 wire. It has the 6-50R for the welder to plug into and at the other end, I will wire a 14-50R. My question is...how to wire the 14-50R.

The cord has black (hot) white (hot?/neutral?) and green (ground) wires. At the 6-50R I have the cord wires as follows---black=hot white=neutral green=ground...as shown in the directions. Am I to wire the 14-50P as follows?----the top ("U" blade) as ground (green wire)...the left blade the hot (black wire)...and the right blade neutral (white wire) and leave the bottom blade empty?"

The response was that is right and label the white wire as red / black to let people know it's hot as well. That look correct?

Thanks,
