∗ These values are applied when the cleaning control knob is set to
Standard. Reduce the current value when it is set to Strong.
Note: In the welding current range of AC and DC electrode negative, the
lower limit indicates the minimum operational current for the pure
tungsten electrode, and the upper limit indicates the maximum
operational current for the thoriated tungsten current.
