A narrow gap arc welding machine that has a shield box around a torch and protects the welding part by a primary shield gas injected from the torch and a secondary shield gas injected from the shield box. An arc monitoring notch is provided at the front of the shield box in the welding direction, and the shielding gas injection port of the secondary shield gas supply tube is opened toward the inside of the shield box above the notch. A narrow gap arc welding machine characterized by: 2. The narrow gap arc welding machine according to claim 1, wherein a gas lens that equalizes the flow of the shielding gas from the secondary shielding gas supply tube is provided between the shielding gas injection port and the arc monitoring notch. A narrow gap arc welding machine, characterized in that the narrow gap arc welding machine is provided in the shield box between the two. 3. The narrow gap arc welding machine according to claim 1 or 2, wherein the shielding gas injection amount from the secondary shielding gas injection port above the notch at the front in the welding direction is set in a direction perpendicular to the welding direction. A narrow gap arc welding machine characterized in that the amount of injection from a secondary shielding gas injection port is approximately twice that of the injection amount.
