PrestonEastin welding manipulators hold the welding head in position relative to the workpiece. They integrate with manual and automated welding positioners and save money by improving welding productivity and quality. They support a full range of manual and automated welding processes.

Our welding head manipulators use a column and boom design to reach over and around the workpiece. They’re often used for welding pipes, tanks and other large fabricated structures.

Unlike side beam carriages, manipulators offer up, down, in and out movement. They also pivot at their bases, which makes them infinitely variable and ideal for a broad range of circumferential and longitudinal seam welding.


Supporting the lightest and heaviest welding heads

Welding manipulators are commonly paired with turning rolls, headstocks / tailstocks and 2-axis positioners. A manipulator paired with a positioner can provide an added level of control to your process, improving quality and repeatability. In manual processes this means better ergonomics for the welder, which raises productivity and quality. In automated welding processes, consistency is higher so there are fewer defects and less rework.

PrestonEastin classifies manipulators into five types based on load capacity:

  • Whitetail 200 Series at 200 Ibs (91 kg) to 400 Ibs (181 kg)
  • Light duty at 300 Ibs (136 kg) to 600 Ibs (272 kg)
  • Medium duty at 650 Ibs (295 kg) to 1200 Ibs (544 kg)
  • Heavy duty at 750 Ibs (340 kg) to 1500 Ibs (680 kg)
  • Super heavy duty at 1100 Ibs (499 kg) to 2600 Ibs (1179 kg)

Collaborate with us for a customized manipulator

Our team’s collaborative process guarantees a customized manipulator that will easily integrate into your welding process. Integrating wireless controls is also possible.

PrestonEastin carefully considers capacity and environmental factors when selecting the right manipulator configuration for your application. To this end, we offer customizations for:

  • Cable Management
  • Control Preferences (e.g., wireless and multiple positioner integration)
  • Input voltages
  • Lift motors
  • Mast / Ram speed ranges
  • Mast / Ram stroke
  • Paint color
  • Ram motors


We offer two standard options for your manipulator’s base: an X-base or travel car.

An X-base provides rigid stability for manipulators supporting heavy loads. They are ideal for cellular manufacturing where relocating your manipulator isn’t a requirement.

Travel cars provide your manipulator with additional versatility by allowing it to traverse between multiple manufacturing cells. PrestonEastin offers two types of travel cars: non-powered travel cars for manual movement and powered travel cars with standard variable frequency drives for an additional level of automation.

Consult with PrestonEastin

Adding a manipulator to welding operations improves productivity and quality, but only if it’s right for your welding operation. Expectations for a pipe welding manipulator differ from those for a unit for tanks, drums or machine bases, so ask the experts at PrestonEastin for advice.

Don’t spend hours evaluating every welding manipulator that’s for sale, save time by coming to PrestonEastin. We’ll help you evaluate your needs and understand your options.
