2T downslope cut
This is a function that allows the user to end the current downslope ramp with a quick press of the torch
switch.
A
AC Balance
Function to adjust the positive and negative current cycles in AC TIG welding. Low percentage means
that, on average, the welding current is more on the negative side, and high percentage that, on average,
the welding current is more on the positive side.
AC Frequency
Function to change the frequency of the alternating current in AC TIG welding. This setting adjusts the
number of cycles per second. Used for changing the frequency of the welding current to best match the
welder's preference and application.
AC phase swap current
Changes the welding current point where crossing the zero begins. Affects only AC TIG.
AC TIG
Alternating current TIG welding process, where the polarity of the electrode alternates rapidly between
positive and negative. Used especially in aluminum welding.
AC Waveform
Function to change the wave form of the alternating current in AC TIG welding. Three options are avail-
able: sine, square and Optima. The wave form affects the shape of weld bead, penetration of the weld and
the noise of the welding process. Select the one that suits the application.
Arc force
Adjusts short circuit dynamics (roughness) of MMA welding by changing, for example, current levels.
Arc time
Tells how long the welding arc has been on.
Auto pulse
TIG welding process, where the welding current alternates between two current levels: base current and
pulse current. Only welding current needs to be adjusted and pulse parameters are preset automatically.
Used for optimizing the arc characteristics for desired welding applications.
B
Balance maximum
Sets the maximum value for AC balance setting.
Balance minimum
Sets the minimum value for AC balance setting.
