Amperage Adjustment Control
To access the User Functions, press and hold
the Amperage (A) and the Gas/DIG controls
until [USER] [MENU] is displayed. To scroll
through the user menu functions, press and
release the Gas/DIG control.
Rotate amperage adjustment control to ad-
just parameter setting.
To exit user menu, press Amperage and Gas/
DIG controls at the same time and then re-
lease, or turn power off.

Description
Tungsten Diameter Selection
[TUNG] [3/32]
Each tungsten size has preset starting parameters specific 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.
Output Trigger Mode Functions
[RMT] [2T]
See Section 9-3 to reconfigure RMT functions.
Independent Amperage Control
[ENEP] [SAME]
Standard mode of operation for controlling 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
[AC] [WAVE]
Use Encoder to select between advanced squarewave [ADVS], soft square-
wave [SOFT], sine wave [SINE], or triangle wave [TRI]. The default is Soft.
Application: Use advanced squarewave when a more focused arc is re-
quired for better directional control. Use soft squarewave when a softer arc
with a more fluid puddle is desired. Use sine wave to simulate a convention-
al power source. Use triangular waveshape when the effects of peak amper-
age with reduced overall heat input is required to help control distortion on
thin materials.
AC Commutation Amperage Selec-
tion (Dynasty Only)
[AC] [COM.A]
Use Encoder to select between [HIGH] or [LOW] AC commutation amper-
age. 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.
