EXAMPLE 1 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
understanding of how each variable affects the welding current.
(1) Prepare the machine for DC TIG welding as per the DC HF TIG operating guide on page 18
(2) Set the Peak Current at 110 Amps
(3) Set the Base Current
