Bare minimum IMHO.

Not necessary, but variable speed is quite desirable.

The inductive ballast stores up energy in the inductance. This
provides raw power for extra-ordinary strikes. The energy is
stored in the mass of copper and iron core of the arc welder.

P.S. I am getting married in Las Vegas this weekend. Please wait
for additional replies until I return 5/2/95.

Thank You.
