Enwere ike ikewa ịgbado ọkụ Pulse TIG na:

DC usu TIG ịgbado ọkụ

AC pulse TIG ịgbado ọkụ.

Dị ka ugboro ole, ọ nwere ike kewaa:

1) Obere ugboro 0.1 ~ 10Hz

2) Ọ bụrụ na 10 ~ 10000hz;

3) Elu ugboro 10 ~ 20kHz.

DC pulse TIG ịgbado ọkụ na AC usu TIG ịgbado ọkụ bụ adabara otu ịgbado ọkụ ihe dị ka nkịtị TIG ịgbado ọkụ.
