Abstract
A spot welding gun adapted for use in robotic welding in which the electrode holding arms of the gun are each turnably journalled on an attachment means. One of the electrode holding arms or an operating lever thereof supports a cam member with a cam surface thereon. A pressure roller acts against said cam surface during transport of the welding gun between welding points and thereby holds each electrode holding arm in a respective fixed position relative to the attachment means.
