(1) To estimate ESO, subtract 1/4” (6.0mm) from CTWD.
(2) For greater percentage of CO2shielding gas, increase voltage by 1-2 volts.
NOTE: Shaded areas are recommended procedures for short circuiting mode with 75-85% Ar/Balance CO2.

Subject to Change — This information is accurate to the best of our knowledge at the time of printing. Please refer to www.lincolnelectric.com for any updated information.
TEST RESULTS
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.
Material Safety Data Sheets (MSDS) and Certificates of Conformance are available on our website at www.lincolnelectric.com
