I've been using the Everlast Powertig 250EX now for a while and really love the darned thing.
I'm welding aluminum like I never had before and really enjoy learning everything I can about the settings and what they do. Now I've got to figure out how I work!
It seems to me that I have a better control of my foot pedal when I use my left foot. I am right handed and when I weld using my right hand holding the torch, I find that my right foot is not as accurate as it can be as compared to my left foot. It just seems more natural to me for my left foot to run the pedal than the right while holding the torch with my right hand. Maybe it is the right side of the brain vs left side of the brain thing? I do notice that when I weld aluminum using the pedal, I can better sinc my pedal to the adding of rod better when using the left foot and my left hand adding the rod while moving the torch with my right hand.
If I hold the torch with my left hand, then the exact opposite. I can better use the pedal with my right foot while adding rod with my right hand.
Anyone else notice this also? Try it right now by pretending to hold the torch and using a foot pedal. Do it right handed and then left. Switching feet. Pretend to add rod......It may surprise you.
Or maybe I am crazy? ...Don't answer that!
