Importance of tungsten condition

Poor condition of your tungsten can be compared to putting bad gas in your car; it’s that simple. TIG or GTAW is a precision process that requires attention to all areas in the system, but the tungsten is the last piece that the electrons flow from, and if it is not maintained in a sharp or clean condition, it will affect the arc. Two of the most important areas are arc staring and directional control, which can have an effect on increased heat input when it is critical to keep this as low as possible. Whatever you do, take the time to recondition your tungsten if you touch it to the work of the fill material.
