Oxy-fuel welding is considered a totally manual process because it relies on the welder's skill and direct control to manipulate the torch and filler metal during the operation. In oxy-fuel welding, the welder uses an oxy-acetylene flame to melt and join metal pieces, and the entire process requires the operator to adjust the flame and apply the material as needed. This hands-on approach allows for precise control but also places the responsibility on the welder to execute the weld correctly.

In contrast, gas tungsten arc and gas metal arc welding can involve automated or semi-automated techniques that assist the welder, which reduces the degree of manual control required. Submerged arc welding is typically more mechanized, using a continuously fed wire electrode and an automatically controlled arc, which minimizes the need for manual intervention. Therefore, oxy-fuel welding stands out as the fully manual option among these choices.
