seems that you have a ground issue. make sure the ground clap is on barte metela and secured tight. make sure your tungsten electrod is about 1/8 of an inch form the edge of the cone. you will find that you will get a faster arc this way.

It sounds like you need to change out your SCR chip on your motherboard; Miller makes one that i have installed on all our 350xl's, I don't have the number on hand but i can get it for you tomorrow.

Testimonial: "appreciate the help."
Common problem with the SUPER series of Chinese machines. If you can provide some photos of the internals I might be able to help you.
