(1)When used with argon gas. The current ranges shown must be reduced when using argon/helium or pure helium shielding gases.

(2)Tungsten electrodes are classified as follows by the American Welding Society (AWS):

Pure

EWP

1% Thoriated

EWTh-1

2% Thoriated

EWTh-2

Though not yet recognized by the AWS, Ceriated Tungsten is now widely accepted as a substitute for 2% Thoriated Tungsten in AC and DC applications.

(3)DCEP is not commonly used in these sizes.

(4)TIG torch nozzle "sizes" are in multiples of 1/16ths of an inch:

# 4 = 1/4 in.

(6 mm)

# 5

= 5/16 in.

(8 mm)

# 6

= 3/8 in.

(10 mm)

# 7

= 7/16 in.

(11 mm)

# 8

= _ in.

(12.5 mm)

#10 = 5/8 in.

(16 mm)

(5)TIG torch nozzles are typically made from alumina ceramic. Special applications may require lava nozzles, which are less prone to breakage, but cannot withstand high temperatures and high duty cycles.
