SELECTING THE PROPER POSITIONER
ROTATING CAPACITY (Fig. 1)
TILT CAPACITY (Fig.2)
Distance Distance Inh.Oh
Load CG
Load(lbs) x Distance(in) = Rotational Torque (in/lbs)
Load(lbs) x (Distance(in)+Inh.Oh(in)) = Tilt Torque (in/lbs)
  • 1. Determine the weight of the item to be welded using the Positioner (including fixtures).
  • 2. Calculate the center of gravity of the item to be welded.
  • 3. Using Fig.1, calculate the rotational torque required.
  • 4. Using Fig.2, calculate the tilt torque required.
  • 5. The Welding Positioner must have the Load Capacity equal or greater than requirements.
