AC NOT RECOMMENDED!
Do not use in an inverter.
AC/DC YES. Great for all purpose welding. Most eco-
nomical.
AC/DC YES. Good for low amp use.
AC/DC YES. Best alternative to 2% Thoriated. Tough
performer.
AC/DC YES. Slight advantage over 1.5% Lanthanated.
AC NOT RECOMMENDED!
Do not use in an inverter.
