The 300kg welding positioner is a small to medium-sized rotary welding auxiliary equipment. It firmly clamps workpieces using a four-jaw chuck, enabling 360° rotation and tilting adjustment to maintain welding seams in the flat welding position. This significantly reduces welding difficulty while improving welding quality and working efficiency. Ideal for circumferential welding of small tanks, pipelines, flanges, elbows, hydraulic cylinder heads, and other circular parts.

• Four-jaw self-centering chuck with strong clamping force for convenient workpiece fixing and centering
• Variable frequency speed regulation with stepless rotation speed adjustment for stable, shake-free operation
• Integral cast base with high structural rigidity, resistant to deformation during long-term continuous work
• Tilting angle adjustable from 0-90° for flexible adaptation to different workpiece welding angles
• Independent control box with hand-held control pendant for easy welder operation
• Voltage customization support: 380V/220V/415V 50/60Hz to match global power supply requirements

• Small pressure vessel fabrication
• Pipeline and flange circumferential seam welding
• Elbow and pipe fitting processing
• Hardware cylinder parts welding
• Stainless steel small tank production
• Engineering machinery parts surfacing welding
