Welding some 20ga 304 stainless with my Miller Econotig. Since it's too thin I'm constantly turning the arc on and off. "Stitch" welding I believe it's called.
Anyway it seems like an electrical connection/switch has melted or something because now it won't start the arc properly at low pedal. It sort of buzzes and has a really weak arc and makes a noise like when the arc won't start. It arcs ok with 3/4 to full pedal but that's way too hot.
I used to stitch weld all the time with my Hobart Handler but this is the first time I've really done it that much with the Econotig.
Has anyone seen this and know the fix?
Will the Econotig handle stitch welding?
