I purchased one for my 250ex as well as the ssc pedal. I got the 25 ft power cables. Don't shy away from the 25 footer as it is so light and small it rolls up as easy as the standard leads that come with the welder. The first thing I noticed when I laid them side by side is the flex loc can not make the same 90 degree bend as the stock torch. So after getting the flex loc in my had and running the first pass I was amazed how the angle works so much better. It's like a 90 but the head sits up on top of the torch. My first pass looked like I had been a welder my whole life. I have a glass lense on it. What a difference this will make for me just because of the comfort of having a lighter torch with a better angle. I truly have more fun welding with it! If your on the fence about getting I hope I pulled you over. 100% worth the money.
Get the SSC foot pedal so much better. Just the motion being smoother is well worth the money.
I know a great welder can make great welds with any torch... But for me this makes better welds right from the word go.
