TIPS: EXTEND ELECTRODE ENOUGH TO GET A DECENT ANGLE SO THAT WALKING THE CUP OR FREEHAND WELDING BOTH WORK WELL.
trail out on thicker part of pipe wall before snapping out to avoid a crater eye. aka fish eye
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.Keep the hot tip of the filler wire shielded by the argon envelope from the tig cup
Snip oxidized tip of filler metal before each restart
