Description
EN Amperage and EP Amperage TIG only:
Controls both electrode negative and positive amperage value.
�
Both EN Amperage and EP Amperage LEDs will be lit.
�
See Section 6-3 to select Independent EN and EP Amperage control.
Balance Control (%EN) TIG Only:
Controls oxide cleaning. Increasing the setting reduces cleaning. Range is BALL, 50
- 99%. Stick is fixed at 50%. "BALL" sets the Balance to 30%. This is to allow the op-
erator to form a ball on the tip of the tungsten. It is not for normal welding operation.
AC Frequency (Hz): Controls arc width. Increasing the setting narrows the arc width.
Range is 20 to 400 Hz.
