Co2 Welding Settings. You can use it in its pure form to weld thicker metals and achieve a deeper weld penetration on steel. The use of the gas mixture of argon and carbon dioxide gives the weld a finer bead finish and creates less splatter than the pure carbon dioxide gas shield.
Youll find the green column splits into two main areas. In the USA co2 mig welding gas is often considered to be inferior to c25. Also if a mig welder is equipped with inductance setting control a higher inductance setting works better for me with co2 gas.
It is the only shielding gas that can be used without the addition of an inert gas.
CO2 is a good choice for welding thick material which requires deep penetration. 100 CO2 shielding gas I chose those settings because its the highest recorded values for 0035 wire dia. Different types of welding machines have various settings that you can change to adjust how they weld. In the USA co2 mig welding gas is often considered to be inferior to c25.
