0370250852 - ESAB RT5 5-Ton Fixed Height Welding Positioner

Industrial-Grade Automation for Heavy Fabrication

The ESAB RT5 Fixed Height Welding Positioner is a cornerstone of efficiency for heavy industrial fabrication shops. Designed to handle substantial loads up to 5 tons, this machine is engineered to manipulate large workpieces—such as pipes, vessels, and complex structural assemblies—into the optimal position for welding. By utilizing the RT5, facilities can transition vertical and overhead welding tasks into the flat (downhand) position, which is critical for maximizing deposition rates, ensuring weld integrity, and meeting stringent code requirements.

The "Fixed Height" designation indicates that the rotational axis remains at a set elevation, providing a rigid and stable base that is mechanically simpler and often more robust for specific repetitive workflows compared to adjustable-height models. The unit features motorized rotation and tilt, driven by high-torque AC motors and precision gearboxes. This drive system is designed to minimize backlash, ensuring that the rotation is smooth and consistent—a vital factor when performing continuous circumferential welds where any stutter could lead to defects. The variable speed control allows the operator to fine-tune the rotation to match the required travel speed of the welding process, whether it be MIG, TIG, or Submerged Arc.

Safety and durability are paramount in the design of the RT5. The table is equipped with a high-amperage grounding system that bypasses the bearings and gears, protecting the machine's internal mechanics from the high welding currents typical in heavy fabrication. The control system is housed in a robust enclosure, and the remote pendant allows the operator to control tilt and rotation from a safe vantage point, ensuring full visibility of the workpiece without being in the immediate hazard zone. For shops looking to increase throughput and weld quality on heavy parts, the ESAB RT5 is an indispensable asset.
