Post up what youve got. I need to make a extension chord for welder power. It has to be 3 conductor of AT LEAST 10GA. I need 50 - 60 feet.
These guys might have that. It’s a big electrical supply house.

Or call Volland Electric. www.volland.com Kind of a sister company of mine. They might be able to hook you up. Tell them an engineer from OGSI (James Fry) referred you.
Go to Home Depot they sell power cable by the ft. then purchase 30A NEMA connectors and make your own. This is the cheapest way to do it trust me
