Patent ID: 6927357

Claim:
A weld gun having a base, first and second arms supported on the base for pivotal motion about a common axis extending laterally between the arms, a pair of laterally opposed electrodes carried on the arms and engageable upon pivotable motion of the arms moving the electrodes toward one another to a closed position, and the improvement comprising: a lever supported on the base and pivotable on a second axis spaced longitudinally from the first axis, the lever having ends spaced in opposite directions from the second axis; the ends of the lever being connected one with each of the first and second arms; and an actuator connected to actuate at least one of the arms in a pivotal motion; whereby actuation of said one arm is operative to pivot the lever to oppositely actuate the second arm in a predetermined manner so that the arms move the electrodes toward and away from one another; and wherein at least one of said ends of the lever is connected with an associated one of the arms through a rod and the rod connects with a resilient member that compresses to allow limited variation of the electrode closed position.
