Core Heavy-Duty Features
Ultra-Rigid Cast Steel Base: Anti-deformation long-term use thick integrated casting base + reinforced rib structure, eliminate shaking under full 300kg load, no frame deformation after years of continuous production.
High Torque RV Reducer: Zero patchy weld seam large torque worm gear reducer with self-locking tilt function; uniform low-vibration rotation avoids uneven, patchy weld surface on thick metal workpieces.
Enlarged Turntable & Multi-Hole Mounting Platform: 400/500mm optional turntable with dense mounting holes, easy to fix large flanges, boiler end caps and medium storage tanks without auxiliary fixture.
Dual Control Mode: Foot Pedal + Digital Panel standard foot switch for hands-free welding; digital panel stores 99 groups heavy-load welding parameters, one-click recall for mass heavy workpiece processing.
Global Voltage Custom & Full Safety Protection: Support 220V single phase / 415V three phase for Middle East, Southeast Asia; overload, overcurrent and emergency stop safety system for heavy workshop operation.
Stable Welding Effect Comparison
Ordinary light positioner under heavy load: Obvious vibration, patchy weld bead, uneven fusion, high reject rate
Our BWJ-300 heavy positioner: Smooth constant rotation, uniform full weld, no secondary polishing, reduce scrap rate by over 60%
Secure heavy flange/boiler barrel on large turntable via fixture or 3-jaw chuck
Adjust tilting angle to 45°/horizontal for optimal welding posture
Set stable rotation speed matching thick-wall welding parameter
Step foot pedal to start uniform rotation, complete full circumferential weld
Emergency stop button available for sudden heavy-load abnormal situation
Target Heavy Industry Applications
Medium pressure vessel & boiler manufacturing factory
Thick steel flange, pipe fitting, chemical storage cylinder workshop
Construction machinery, water treatment tank production line
Overseas engineering traders for palm oil, chemical, heating equipment production
Frequently Asked Questions
Q1: What is the maximum horizontal load of BWJ-300 positioner? Can it bear full 300kg thick boiler barrel?
A: Rated horizontal load reaches 300kg, equipped with reinforced cast base and high torque reducer, stably support full-load thick boiler, chemical tank and large flange continuous welding.
Q2: Will thick heavy workpiece cause vibration and patchy weld seams?
A: Built-in large torque self-locking reducer and shock-absorbing base, extremely low vibration during full-load rotation, weld surface uniform without patchy uneven marks, meet pressure vessel production standards.
Q3: Can this heavy positioner coordinate with your 500mm longitudinal seam welder for complete tank production?
A: Perfect matching, form automatic production line for medium cylinder straight seam + circumferential welding, one-stop solution for overseas tank factories.
Q4: Can we customize three-phase 415V voltage for Middle East industrial workshop?
A: Support full voltage customization, 220V single phase standard, 415V three-phase industrial power supply optional, complete CE certificate for customs clearance in Qatar, UAE, Indonesia.
Q5: Does the machine have overload protection for heavy workpieces?
A: Equipped with overload, overcurrent and emergency stop triple safety protection, automatically cut power to avoid motor and gearbox damage under abnormal heavy load.
Q6: How long is the warranty of core heavy-load transmission parts?
A: Servo motor, RV reducer and digital control box enjoy 1-year free warranty, lifelong online technical guidance and spare parts supply.
