AC Commutation Amperage Selection (Dynasty Only)
Use Encoder to select between [HIGH] or [LOW] AC commutation amperage. Default is High.
Application: Use High commutation amperage when a more aggressive arc is preferred. Use Low commutation amperage when a less
aggressive and quieter arc is preferred.
Arc Starting Mode Selection (Stick)
[HOTS] [ON]
Provides additional amperage while striking the electrode to prevent the electrode from sticking.
[HOTS] [OFF]
No additional starting amperage to assist in starting the electrode.

Tungsten Diameter Selection
Each tungsten size has preset starting parameters spe-
cific to that diameter for optimized starting. Range is
0.020−3/16 in. or 0.5−4.8 mm. To manually set starting
parameters, see Section 15-3.
Output Trigger Mode Functions
See Section 9-3 to reconfigure RMT functions.
Independent Amperage Control
[ENEP] [SAME] - standard mode of operation for control-
ling AC amperage setting.
[ENEP] [INDP] - for AC TIG welding allows the user to set
the EP amperage independently from the EN amperage.
When [INDP], the user can set the EP waveshape (sine,
square, triangle) independently from the EN waveshape
(see Section 6-4).
AC Waveshape Selection
Use Encoder to select between advanced squarewave
[ADVS], soft squarewave [SOFT], sine wave [SINE], or
triangle wave [TRI]. The default is Soft.
Application: Use advance squarewave when a more fo-
cused arc is required for better directional control. Use
soft squarewave when a softer arc with a more fluid
puddle is desired. Use sine wave to simulate a conven-
tional power source. Use triangular waveshape when the
effects of peak amperage with reduced overall heat input
is required to help control distortion on thin materials.
