PURPOSE: A turning gun apparatus is provided to smoothly perform a spot welding using a welding unit by rotating the welding unit in a hundred and eighty degrees through converting a linear motion of a turning cylinder to a rotational motion. CONSTITUTION: A turning gun apparatus comprises a body(100), a turning unit(200), a welding unit(300) and a power supply unit(400). The turning unit is mounted to the upper side of the body and changes a linear motion of a turning cylinder(220) to a rotational motion. The welding is installed to the turning unit to rotate. The power supply unit supplies an electric power to the welding unit. The turning unit includes a turning housing(210), the turning cylinder, a rack bar and a rotator(240). The rotator includes a pinion gear which couples with the rack bar.
