Set up and operation for DC PULSE TIG Welding
EXAMPLE OF PULSE DC TIG WELDING - SETUP PARAMETERS:
Material = Stainless Steel x 2.0mm / Tungsten Electrode = 1.6mm 2% Thoriated / 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
example 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 un-
derstanding of how each variable affects the welding current.

The value selected is the number
of times the current switches
from Peak Amp to Base Amp per
second
The value selected is the % of
time the Peak Amp is on during
each pulse cycle.
