I havent thought of that (great idea) but what I did do with the stud welder was connect a ground clamp to the outer ring (like a mig grounded to the car) and short the tip so it didnt need to be pressed ,it welded as soon as it touched the steel (no spring pressure) That was one of my closely guarded secrets..Now the whole world knows and that feature will be out on the next model...
.but the whole point is to modify the mig so everyone can do it not just the lucky few with stud welders...Keeping in mind this is only for small dents...
