A welding information providing apparatus comprising:

• a main body provided to be worn by a user;
• a display unit arranged in the main body and including a display for displaying a welding image to the user;
• a primary lens member arranged on a path through which the welding image provided from the display travels and including a convex surface for adjusting a size of the welding image to allow the welding image to reach both eyes of the user, wherein the primary lens member is rotatable about an axis located within the primary lens member and extending between a first end of the primary lens member and a second end of the primary lens member and wherein a surface of the primary lens member facing the display is adjustable in angle with respect to the display;
• at least one camera mounted on an outer side of the main body and configured to obtain a welding image frame with respect to a welding operation;
• a processor configured to control the display to display the welding image generated based on the welding image frame,
• a front body protruding from the main body, in which the display unit and the primary lens member are arranged, wherein the front body is configured to maintain a state in which the display unit and the primary lens member are spaced apart from each other such that the display unit and the primary lens member are arranged along an imaginary center line passing through a center of the display unit, and
• a lens frame coupled to the front body, wherein the lens frame is configured to support the primary lens member and rotate the primary lens member relative to the front body about the axis.
