Large Diameter 600mm Pulse MIG Light Pole Welding Machine with 12m Welding Stroke for Street Light Poles

CNCS600/12000 CNC pole shut welding machine is an upgraded large-diameter automatic welding solution designed specifically for oversized street light poles. Adopting full CNC servo drive and advanced Pulse MIG welding technology, this equipment supports pole diameters up to 600mm, covering most large-size conical and octagonal lighting pole production demands. Featuring non-hydraulic mechanical structure, intelligent adaptive clamping and low-spatter welding performance, the machine delivers high-precision seam forming with minimal post-processing. It is a highly efficient, low-maintenance automated welder for modern large-scale light pole manufacturing.

• Large-Diameter Adaptability: Upgraded structure supports 600mm maximum pole diameter, perfectly catering to oversized street lamp pole production that ordinary models cannot handle. Compatible with both round tapered poles and multi-sided octagonal poles with strong production flexibility.
• High-Quality Pulse MIG Welding Output: Uses professional argon-rich mixed gas formula (85~90% Argon + 10~15% CO₂). Produces ultra-smooth weld seams with minimal spatter, eliminating heavy post-polishing work. Welded poles maintain perfect roundness without burning or deformation.
• Intelligent CNC Adaptive Clamping: Equipped with three sets of servo-controlled presser feet and precision V-groove workbench. The system dynamically adjusts clamping pressure, foot position and running speed according to real-time pole taper and diameter changes, ensuring consistent seam closing effect for every workpiece.
• Zero Hydraulic Failure Design: Fully mechanical servo structure abandons traditional hydraulic systems, completely avoiding oil leakage, oil contamination and frequent hydraulic maintenance. Machine stability is greatly improved with lower factory operating costs.
• High Tolerance for Workpiece Errors: Self-developed adaptive algorithm compensates minor diameter differences in mass-produced poles, ensuring stable welding yield even with slightly inconsistent raw materials.
• Near-Zero Edge Welding Gap: Optimized welding stroke design realizes full-length welding from top to bottom. The residual unwelded edge is extremely narrow, greatly reducing or even eliminating manual repair procedures.
• Surface Protection & Low-Labor Operation: Multi-point pressure dispersion design avoids pole surface indentation and extrusion marks. Fast trolley reset and ergonomic loading structure effectively reduce operator workload.
• Precision Weld Positioning System: Rear pole guiding structure stabilizes workpiece running track, reducing repeated weld gun calibration and improving continuous production efficiency.
• Visual Weld Monitoring: Onboard camera transmits real-time weld images to the control screen, allowing operators to observe and track seams easily and improve welding accuracy.
• Rich Expandable Functions: Support rotary flipping device, dual welding system upgrade, automatic loading/unloading and remote network diagnosis, meeting diversified and intelligent production upgrade needs.

• Independent Submerged Arc Welding System: Professional configuration for thick plate heavy welding requirements.
• Automatic Loading & Unloading System: Matched material storage racks realize automatic feeding and discharging, saving manual handling cost.
• Rotary Roller Device: Automatically flips workpieces to complete double-seam welding, specially designed for dual-seam lamp poles.
• Remote Network Function: Supports remote fault diagnosis, online parameter modification and system upgrade to reduce equipment downtime.
• Complete Welding Spare Parts Package: Customized spare parts for different welding configurations to ensure continuous production.

This equipment is specially applicable for automatic longitudinal seam welding of 6–12m extra-large diameter street light poles. It covers oversized conical poles, wide-spec octagonal poles and thick-wall lighting poles, widely used in municipal engineering, road lighting and large-scale pole manufacturing factories.

It supports a maximum 600mm pole diameter, covering large-size lamp poles that standard models cannot process. The upgraded servo structure and adaptive algorithm ensure higher stability for oversized workpieces.

No. The argon-rich mixed gas welding produces extremely low spatter and flat weld texture. Most finished poles can be directly used without polishing, greatly improving production efficiency.

Yes. Equipped with optional rotary roller device, the machine can automatically rotate the pole to finish the second seam, realizing one-machine multi-process production.
