This blend is primarily used for spray transfer on stainless steels. One percent oxygen is usually sufficient to stabilize the arc and improve the droplet rate and bead appearance.

This blend provides a more fluid but controllable weld pool. It is the most commonly used argon-oxygen mixture for general carbon steel welding. The additional oxygen also permits higher travel speeds.

When welding thicker metals or in specific environments, a mixture of argon and helium is used to improve the welding process’s overall performance.

Balance the heat intensity of helium with stability & control by Argon.
