TIG: Bi-level option and Pulsing

[Rotosan1980]

Ciao,

I'd like to know when the bi-level option should be used in TIG welding. What this option consist in?

About Pulsating: how should the pulsing frequency be set? Is possible to set the minimum and the maximum value of the current and which are the criteria to set them?

Thank you very much for your help

Ciao Gianluca

Try this thread. Some cheaper kit has little to no adjustments, peak (maximum) to background (minimum) amperage ratios are fixed, some have stepless frequency adjustment others just a choice of 2 pulse frequencies. Full featured kit EVERYTHING is adjustable- minimum/maximum amperages, pulse width (time spent at each amperage) and pulse frequency

A lot of it is personal preference from experimentation, generally used on thin and/or heat sensitive materials
