  • Multi-arm weld gun
    Patent number: 6512194
    Abstract: A multiple arm weld includes at least two weld gun arms where one arm retracts away from mating work pieces while at least one other arm remains operational, thus allowing a multiple arm weld gun to act as a single arm weld gun. Once one or more weld gun arms is retracted, the remaining weld gun arms may be repositioned with respect to the work pieces in a space not previously accessible to the multiple arm weld gun before retraction of an arm.
