Set up and operation for AC PULSE TIG Welding
EXAMPLE OF PULSE AC TIG WELDING - SETUP PARAMETERS:
Material = Aluminium x 3.0mm / Tungsten Electrode = 2.4mm Zirconiated / Gas = Argon
The following steps are a guide as a starting point for you to set the machine up in Pulse mode to give an ex-
ample of welding in Pulse mode function. You can experiment by changing any of the variables to see what
effect it has over the welding and what the end result can be, but it is suggested to change only one variable at
a time and then check the welding to see what the result is, in this way you acquire a better understanding of
how each variable affects the welding current.

1. Select Pulse Mode
Select Pulse welding
mode by the pushing the
PULSE button to select
and illuminate the pulse
icon.
Selecting Pulse Parameters
Select pulse parameters by turning the
encoder to cycle through the front
panel to select the pulse parameter
icons and make settings as show in the
following step by step procedure.
Turn the Encoder to set
the Base Amperage
The setting shows on the digital
display.
Push the Encoder to
lock the icon ready for
adjustment.
Base Amp : Turn the
encoder to cycle through
to illuminate the Base
Amp icon.
3. Select Base Amperage
Turn the Encoder to set
the Base Amperage
The value selected is the number
of times the current switches
from Peak Amp to Base Amp per
second
Push the Encoder to
lock the icon ready for
adjustment.
Pulse Hz : Turn the en-
coder to cycle through to
illuminate the Hz icon.
4. Select Pulse Frequency Hz
Turn the Encoder to set
the Base Amperage
The value selected is the % of
time the Peak Amp is on during
each pulse cycle.
Push the Encoder to
lock the icon ready for
adjustment.
Pulse % : Turn the
encoder to cycle through
to illuminate the Pulse
%
icon.
5. Select Pulse Width
2. Select Peak Amperage
Peak Amp : Select by
turning the encoder to
cycle through to illuminate
the Peak Amp icon.
Turn the Encoder to set
the Peak Amperage
The setting shows on the digital
display.
Push the Encoder to
lock the icon ready for
adjustment.
