That's why the range from about 2-30 pps is no-man's land for me.

I'm using it primarily on aluminum to prevent burning holes. Without the pulse, I have trouble welding .032 aluminum sheet . . . I'm putting a new body on a Lotus 7. Pulsing makes it easier for me to control the size of the keyhole. YMMV.

Thanks for the reply,
