2-Axis Positioners
Efficient and precise welding depends on the
right positioning.
PrestonEastin two-axis welding positioners
are ideal for construction, OEM, oil & gas, and
contract manufacturing applications where
increased efficiency and safe operation is strongly
desired. Our robust product line delivers precise,
repeatable, and safe operation. Better positioning
yields higher quality welds, improved productivity,
and a lower risk of operator injury.

Rotational Torque Calculation
1. Determinetotalweightofworkpiece,includingfixtures.
2. Calculate the load center of gravity distance (LOAD C.G.) in inches, from center of table.
3. Multiply information from step 1 times the information in step 2 for required rotational
torque.
4. Compare the required rotational torque with the rated rotational torque from the table.
5. Select a positioner with a rotational torque rating equal to or greater than the required
rotational torque.
LOAD X DISTANCE = ROTATIONAL TORQUE REQUIREMENT
(LBS.) X (INCHES) = (LBS. – INCHES)
Tilt Torque Calculation
Positioner
Tilt Capacity
1. Determinetotalweightofworkpiece,includingfixtures.
2. Calculate the load center of gravity distance (LOAD C.G.) in inches, from
thetableface,includingthefixture.
3. Add inherent overhang distance (INH. OH.) in inches to step 2.
4. Multiply information from step 1 times the sum of step 2 and step 3 to
determine the required tilt torque.
5. Compare the required tilt torque with the rated tilt torque from the table
below.
6. Select a positioner with a tilt torque rating equal to or greater than the
required tilt torque.
LOAD X DISTANCE + INHERENT OVERHANG = TORQUE RATING
(LBS.) X (INCHES) + (INH. OH.)
= (LBS. – INCHES)
