*As a general rule, set amperage using 1 amp for every .001" of metal thickness for aluminum. Less is required for DC.
METAL THICKNESS
1-3 mm/.040"-1/8"
3-6 mm/ 1/8"-1/4"
6-10 mm 1/4"-3/8"
METAL THICKNESS
< 1 mm/.040"
2 mm/.080"
3 mm/ 1/8"
4-5 mm/ 3/16"
6-10 mm/ 1/4"-3/8"
TYPE
Pure 100% Tungsten
Thoriated 2% Thorium
(slightly radioactive)
Ceriated 2% Ceria
Lanthanated 1.5% Lanthanum Gold
Lanthanated 2% Lanthanum
Zirconiated 1% Zirconia
NOTE: Thoriated tungsten is slightly radioactive, but is commonly used in the US. Care should be used when grinding so as
not to breath the dust. If you have concerns about Thoriated (red) tungsten, choose from Lanthanated or Ceriated tungsten.

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.
