The Razorweld TIG machine has digital pulse frequency control. All the parameters for DC Pulse Tig

welding - Peak Amp, Base Amp, Pulse Frequency and Pulse Width are easy to set via the digital control

panel.

EXAMPLE OF PULSE DC TIG WELDING - SETUP PARAMETERS:

Material = Stainless Steel x 5/64 / Tungsten Electrode = 1/16 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.

Time = 1 Second (Hz)
