Compact 30kg Welding Positioner | Bench-Mounted Rotary Table
Compact Tilt & Rotate Welding Positioner for Pipes, Flanges & Small Fabricated Parts
The MecBase BWJ-30 Welding Positioner is a compact bench-mounted rotary welding table designed for controlled positioning and rotation of small workpieces during welding.
With a 30 kg horizontal load capacity, Ø310 mm rotary table, 0–90° manual tilt and variable-speed rotation, the BWJ-30 provides a practical solution for small pipe, flange, fitting and component welding.
A center through-hole allows suitable long workpieces to pass through the table, while optional 125 mm, 200 mm and 300 mm welding chucks provide flexible workpiece clamping.
Available in both standard variable-speed and PLC-controlled configurations, the BWJ-30 can be used for manual welding or integrated into a compact semi-automatic welding workstation.

Compact Welding Positioner for Small Workpieces
The BWJ-30 combines workpiece rotation, angular positioning and optional chuck clamping in one compact machine.
Instead of repeatedly stopping and manually repositioning a pipe or flange, the operator can secure the workpiece to the positioner and rotate it at a controlled speed during welding.
The table can also be manually tilted from 0° to 90°, helping place the weld joint in a more accessible working position.
For applications requiring more automation, the BWJ-30PLC version adds programmable rotation speed and angle control, pneumatic torch-holder control and parameter memory.
Key Features
30kg Compact Load Capacity
- The BWJ-30 is designed for small and medium-size workpieces that do not require a large industrial welding positioner.
- The rated load depends on table orientation:
- Horizontal Load: 30 kg
- Vertical Load: 15 kg
- This distinction is important when selecting a welding positioner because tilting the workpiece changes the load and moment acting on the rotary mechanism.
Ø310 mm Rotary Worktable
- Stable Mounting Surface with Center Through-Hole
- The BWJ-30 features a Ø310 mm rotary worktable, providing a mounting surface for the workpiece, fixture or compatible welding chuck.
- A center through-hole is available in: Ø25 mm or Ø65 mm depending on configuration.
- The through-hole design is particularly useful when working with suitable pipes, shafts and other elongated components that need to extend through the center of the positioner.
Variable-Speed Rotation
- Match Table Speed to Your Welding Application
- The standard BWJ-30 uses a 60W DC motor with stepless speed regulation.
- Available rotation ranges listed by the source include: 1–15 rpm or 0.5–7 rpm
- The PLC version provides: 0.1–10 rpm
- This allows the rotation speed to be selected according to the workpiece diameter and welding requirements.
0–90° Tilting Worktable
- Position the Weld Joint at a More Convenient Angle
- The rotary table can be manually tilted from: 0° to 90°
- The original design uses a worm-gear tilting mechanism with a manual handle, allowing the operator to adjust the table angle according to the workpiece and welding position.
- This combination of rotation + tilt makes the BWJ-30 more versatile than a simple horizontal welding turntable.

Product Details – Complete Functionality
Cast-Iron Rotary Table
Stable Workpiece & Fixture Mounting
The BWJ-30 uses a cast-iron rotary worktable with a center opening.
The Ø310 mm table provides a stable mounting surface and can be combined with different chuck sizes for different workpiece requirements.
High-Copper Conductive Carbon Brush
Dedicated Welding Current Path
The BWJ-30 incorporates a conductive carbon-brush system for welding grounding.
The source specifies: 300A Continuous Welding Current
This provides an electrical path for welding current through the rotating system.
Manual Worm-Gear Tilt
Quickly Adjust the Worktable Angle
A manual worm-gear mechanism allows the operator to adjust the rotary table from 0° to 90°.
This provides flexible workpiece positioning while maintaining a compact machine structure.
Foot Switch Control
Hands-Free Start / Stop Operation
The BWJ-30 is supplied with a foot switch, allowing the operator to control table operation while keeping both hands available for welding and torch handling.
This is particularly useful during manual circumferential welding.
Typical Applications
- Small Pipe Welding
- Use a compatible chuck to hold and rotate suitable pipe workpieces during circumferential welding.
- Flange Welding
- Controlled rotation helps maintain continuous movement around suitable flange joints.
- Fitting Welding
- Suitable for elbows, sleeves, couplings and other small rotational workpieces where the geometry and weight fit the machine capacity.
- Small Vessel & Cylindrical Component Welding
- The rotary table can support small cylindrical fabrication tasks within the positioner’s rated load and moment limits.
- TIG Welding
- Variable-speed rotation can be used to maintain controlled workpiece movement while the torch remains in a suitable welding position.
- MIG/MAG Welding
- Can be integrated with a torch holder and appropriate welding equipment for repetitive circumferential welding.
- Welding Training & Small-Batch Production
- The compact bench-mounted design is suitable for training facilities, fabrication shops and production cells where a large industrial positioner is unnecessary.
