  1. Lindaw

    After finally finding the correct pigtail, I am happy with my purchase. Only issue is plug in does not twist lock as expected. For my purposes, that feature is not absolutely necessary, so I’m ignoring that. Otherwise, everything I hoped it would be.

  2. Gale Walker

    I haven’t used the power cord yet, but the cord is heavy duty and well made!

  3. Ian Durham

    Cable is thick and sturdy. This cable allowed me to connect my welder to my generator no problem.

  4. Richard L Gholston

    I needed this adapter for my new inverter welder to run on my 30 amp 220 circuit. Perfect fit and functions for half the cost of making one from parts. I searched all local sources and this style was not available, so I was very happy to find an online source. Be sure to check male and female configuration to make sure this is the right adapter for you.

  5. Thomas Tobin

    I haven’t had the time or ability to use this product yet but after looking it over, I have no doubt that it will work as expected. Upon inspection, this adapter is build for long term use, The heavy gauge wire and ends are built with quality in mind. I did check to make sure the ends would fit on my generator and welder and they connected like I had hoped. You can’t go wrong with this adapter.

  6. Big Mama

    Holy cow! What a well built cable. I am very glad I have purchased this cable. I made one in the past but it was damaged in a field. The components alone minus the 220v cable I had added to almost the price I paid for this bad boy. The cable is super stiff, as my cable that I made is really for supplying equipment in a plant from the roof. I have read a review about it not twist locking in so we will see if that was just the reviewers generator as I would think the stiffness and length would cause a problem. I will leave a better review once I actually use and hook up.

  7. Ed Wisenbaker

    Needed an adapter for my Hobart welder because the 240 on my generator only accepted the round type plug. This works great!!!Update:When I first bought this it fit my cords really tight. But now that it’s broke in a little it installs and removes with relative ease.

  8. FJL

    We had to buy 3 separate plugs to connect the 220 on the wall to the TIG Welder via heavy duty extension cord. After comparing the various ends this was one of the components and it worked perfectly.

  9. JohnNY

    This cord is incredible. The quality of manufacturing is second to none. Gave me the ability to weld anywhere with my generator. No reason to pay more when this thing is the best in my opinion.

  10. PJDSR

    I’m in love with this pigtail! I attempted to build one, but mis-wired it somehow and was only getting 110v. This baby is fantastically well built; it will last me the rest of my life!!!!
