(1)To estimate ESO, subtract 1/4” (6.0mm) from CTWD.

(2)For greater percentage of CO2 shielding gas, increase voltage by 1-2 volts.

NOTE: Shaded areas are recommended procedures for short circuiting mode with 75-85% Ar/Balance CO2.

T E S T R E S U L T S

Test results for mechanical properties, deposit or electrode composition and diffusible hydrogen levels were obtained from a weld produced and tested according to prescribed standards, and should not be assumed to be the expected results in a particular application or weldment. Actual results will vary depending on many factors, including, but not limited to, weld procedure, plate chemistry and temperature, weldment design and fabrication methods. Users are cautioned to confirm by qualification testing, or other appropriate means, the suitability of any welding consumable and procedure before use in the intended application.
