Abstract
A connection member in a welding gun for a robot having a cradle of the welding gun generates less stress by directly connecting the cradle with a robot wrist, whereby the welding gun is positioned as close as possible to the robot wrist. The welding gun for robot can be shortened by accommodating a welding transformer inside a hollow frame defined in the cradle.
