Key Features & Benefits
1. Heavy-Duty 300kg Load Capacity
The BWJ-300Z is designed to support workpieces weighing up to 300kg in the horizontal position and 150kg in the vertical position.
Its reinforced construction provides stable workpiece support for medium-to-heavy fabrication tasks, helping reduce manual repositioning during circumferential welding.
2. Smooth Rotation with Adjustable Speed
Powered by a 120W motor, the positioner features a variable rotation speed of 0.5–5 RPM.
Stepless speed adjustment allows operators to select an appropriate rotation speed according to the workpiece diameter and welding requirements.
Forward and reverse rotation functions provide additional operating flexibility.
3. Adjustable 0–90° Tilting Worktable
The BWJ-300Z features a manually adjustable tilting mechanism that allows the worktable to move between 0° and 90°.
Clear angle markings help operators identify the table position and adjust the workpiece to a convenient welding angle.
The manual adjustment handle allows practical and controlled positioning during setup.
4. Integrated Welding Current Connection
The positioner features a conductive carbon brush assembly and welding current connection arrangement.
A 300A-rated connection cable is described in the standard product design, supporting the welding current return path during compatible welding operations.
This arrangement helps provide a dedicated electrical connection for the rotating worktable.
5. Convenient Foot Pedal Operation
The foot switch allows operators to control worktable rotation without continuously using the main control panel.
This hands-free operation is especially useful during repetitive circular welding tasks where maintaining the welding torch position is important.
6. Flexible Welding Automation Options
The BWJ-300Z supports optional welding accessories, including welding chucks, pneumatic tailstocks, torch holders and welding control systems.
Optional timer controls and welding machine linkage can support semi-automatic welding processes.
For more advanced applications, a compatible PLC touchscreen system may provide programmable rotation settings, pneumatic torch holder control and parameter storage.

Frequently Asked Questions
Yes. The BWJ-300Z can be configured with compatible 200mm, 250mm or 300mm welding chucks, depending on the workpiece and mounting requirements.
The machine can provide independent workpiece rotation. For synchronized operation with a welding power source, the available control interface and equipment compatibility must be confirmed.
No. The stated horizontal load capacity is 300kg, while the vertical load rating is 150kg. Safe loading also depends on workpiece size, center of gravity and mounting position.
Important factors include workpiece diameter, weight, clamping range, jaw configuration, chuck mounting compatibility and the required rotation speed.
Optional timer controls, welding machine linkage and PLC-based configurations may support semi-automatic or automated applications. Compatibility should be reviewed before ordering.
Please provide your workpiece dimensions, maximum weight, welding process, preferred chuck size, order quantity, electrical requirements and delivery destination.
