A widely used tig welding technique for stainless steel is called “walking the cup”. But it does not always work best. And for some applications, it is not permitted because it leaves scratches on the surface of the metal sometimes. A Tig Finger comes in handy for situations where walking the cup does not work or for where those scratches the tip cup makes on and around the weld are not tolerate.
Both Tig welding techniques are shown along with a shameless plug for my Tig Finger product.
