    It’s a great heavy duty extension cord. I use it for my welders around the house. I have had no problems with it. Highly recommend. Just wish they made a 100ft option, if they did I’d buy immediately.

    Was not expecting it to be as heavy duty as it described! Worth every dollar! Been using it for my welder and works very well!

    This is for sure a heavy duty extension cord. Price is also competitive for length and gauge of this beast.

      We don’t joke about it being heavy-duty 🙂 This cord is quite tough and at 6 AWG it can handle more power than others that use smaller wire. Glad you are pleased with your purchase.

    This cord is very heavy; well made; and quick service…highly recommend!

    A number 6 cord may sound like overkill but it’s not if you want 50 amps 50 foot out without to much voltage drop effecting your weilder. The only downside is its bigger and heavier than most garden hoses, a lot heavier.

    Cannot beat it for the money IF you could even find one! One item of note and I think this is misleading. The main leads are 6AWG. The ground is 8AWG. Nowhere in the description is this mentioned. It SHOULD be spelled out IMO. So far works excellent though.

      Thank you for the helpful review. I’m glad you’re pleased with the quality and value of our heavy-duty cord. I have also edited the description now to clarify that the power leads are 6 AWG but the ground is 8 AWG.

    Very heavy-duty. About 1 inch diameter, this will last for many years, long after I’m gone.
