TIPS: GET THE PUDDLE MOVING WITHIN 3 SECONDS.

Aim for an arc length that is equal or less than the diameter of your tungsten electrode.Torch angle can be forgiving provided your arc length is tight.  

For TIG welding 300 series stainless to high strength steels, either a 309L or 312L filler rod can be used.

Both work fine but 312 is very crack resistant

We have both 309 and 312 TIG rod at weldmonger.com
