The whole machine frame adopts high-quality carbon steel material. Integral welding structure ensures high hardness, good toughness and strong compression resistance, effectively avoiding deformation and cracking during long-term repeated operation.
The rotary table is made of premium cast iron, featuring high density, wear resistance and stable rotation. It is not easy to rust or deform, ensuring long-term positioning accuracy and supporting repeated clamping of workpieces.
The equipment surface adopts professional electrostatic spray painting process. Uniform paint layer realizes dust-proof, anti-corrosion and anti-rust performance, adapting to harsh welding workshop environment.
All welding joints and sharp corners are manually polished smoothly, no burrs. Effectively prevents scratch damage to operators and workpieces, improving overall equipment durability and appearance grade.


This desktop welding positioner is rated at 50kg, specially designed for light-duty small workpieces such as flanges, pipes and ring fittings, ensuring stable rotation and precise positioning.
Equipped with industrial VFD stepless speed control system. The rotation speed is adjustable smoothly with soft start and stop, effectively preventing workpiece shaking during welding.
It is fully compatible with TIG, MIG, ARC and other common welding processes, widely used for circular seam welding and auxiliary assembly of small metal workpieces.
Featuring compact structure and plug-and-play design. No complicated installation and debugging required. Ordinary workers can master the operation quickly.
Adopts carbon steel body and cast iron worktable with anti-rust surface treatment. It owns stable performance and low failure rate, requiring only simple daily cleaning and maintenance.
