*As a general rule, set amperage using 1 amp for every
.001”
of metal thickness for aluminum. Less is required for DC.

COLOR
PROCESS
RECOMMENDATION
Pure
100% Tungsten
Green
AC
NOT RECOMMENDED!
Do not use in an inverter. Designed for use in
a transformer only.
Thoriated
(slightly radioactive)
2% Thorium
Red
AC/DC
YES. Great for all purpose welding. Most eco-
nomical. Best for DC, Good for AC. Excellent
arc starting.
Ceriated
2% Ceria
Orange
AC/DC
YES. Good for low amp use. Good for AC and
DC. Some fade out in performance at the
higher end of the range may be observed over
other types. Good arc starts.
Lanthanated
1.5% Lanthanum
Gold
AC/DC
YES. Best alternative to 2% Thoriated. Tough
performer. Good for AC and DC.
Lanthanated
2% Lanthanum
Blue
AC/DC
YES. Slight advantage over 1.5% Lan-
thanated. Best for AC and DC use. Good arc
starting. Holds point well in AC and DC.
Zirconiated
1% Zirconia
Brown
AC
NOT RECOMMENDED!
Do not use in an inverter. Designed for Trans-
former use only.

May be used with good results, but metal com-
position and quality may vary. Not an industry
standardized type. Many blend in Zirconiated,
which is typically not recommended for inverter
use. Personal experience and brand experi-
mentation may be required to obtain best and
most consistent results.
