TIPS: KEEP A TIGHT ARC ..practice restarts until they blend in

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
