  • 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

  • Definitely worth the price.
Color: 25ft
Really heavy duty welding extension cord. It handles my needs and was a fair price. Bonus, it smells like cherry candy for some reason.

  • Nice and flexible
Color: 50ft
Super nice cord. Very flexible thanks to it being EPDM insulated. Works as intended. But man this thing STINKS. Like literally smells so bad I had to take it out of the house. The chemical smell is very overwhelming. Hopefully that goes away with time. Be prepared too cause this thing is heavy.
