    • Amazing cable!
Color: 25ft
Wow primeweld is on another level this has to be the highest quality cord I've bought I have a primeweld welder and a ev that I charge so this cord is a game changer. Some people seem to have complained about the smell of the cord I can tell you that mine I got had no smell at all either it was manufactured a while ago and that's why there's no smell and it dissipated over time or their new manufacturing doesn't make it smell either way the cord has no smell The cord has no problem pushing max amperage though it's self I am using primewelds 6-50 splitter too with this cord and omg these are quality the cord is extremely flexible for how damn thick it is and when I plug things into it like my car charger or my primeweld welder it glides in and out like butter on a hot pan I really like that because with cables this thick the ends can sometimes be hard to insert into the receptical It weighs enough to give you a sweaty face moving it around but maybe that's just me the length is important and let me tell you why this cord is big enough that you really don't want to have a lot of extra cord laying around if you have a small building I have a small 1 car garage and the 25 feet is perfect for me but if you have a 2 car garage I would recommend 100 feet if you plant on having things plugged into this on the farthest point from your recptical. ... show more

    • This is a high quality cord worth the money it costs!
Color: 50ft
I bought this 6/3 50’ extension cord to run my Lincoln Inverter welders off of my Westinghouse portable generator. It is everything I hoped it would be and needed it to be. This cord is very pliable and a high quality addition to my welding equipment. I would buy this cord again in a heartbeat.

    • HEAVY DUTY!
Color: 25ft
Excellent cord. It;s freakin huge to handle the power, so it's a bit tough to handle and store. But it does exactly what it's supposed to. I didn't have the issue with the smell others have eluded to....
