CNC Pole Shut Welding Machine | 12m Pulse MIG Street Light Pole Welding Machine

CNCS400/12000 CNC Pole Shut-Welding Machine is a full-automatic longitudinal straight seam welding machine specially designed for conical round light poles and octagonal light poles. Adopting full CNC and full servo control, non-hydraulic structure and advanced Pulse MIG welding system, this equipment realizes automatic clamping, self-adaptive taper adjustment and one-piece straight seam welding for long light poles. It features no welding deformation, no burn-through, ultra-low spatter and zero manual repair welding, which is the ideal automated equipment for mass production of municipal street light poles.

This welding machine adopts modular integrated structure, including the following core components:

• V-slot mobile trolley with gear and rack driving mechanism
• Long stable worktable with guide wheels at both ends
• High-precision servo drive system for trolley
• 3-direction clamping roller main machine head for tapered & octagonal poles
• Complete Pulse MIG welding system (AOTAI welding power source, wire feeder and welding torch)
• CNC electrical control system & real-time weld monitoring system
• Matching clamping roller molds for different pole types

• Heavy-duty Model CNCSM400: Support max 8mm thick plate welding, suitable for heavy specification light poles.
• Dual Welding System (Pulse MIG + Submerged Arc Welding): Double welding functions for multi-working condition switching.
• Single Submerged Arc Welding System: Professional thick plate welding configuration.
• Automatic Loading & Unloading System: Equipped with left and right storage racks, realizing automatic pole feeding and discharging to improve production capacity.
• Remote Network Function: Support remote fault diagnosis, parameter adjustment and software upgrade, reduce equipment downtime.
• Complete Welding Spare Parts: Optional dedicated spare parts for different welding systems to ensure continuous production.

Suitable for automatic longitudinal straight seam welding of 6-12m municipal street light poles, conical poles and octagonal light poles. Widely used in standardized mass production of various steel lighting poles.

Yes. Full CNC servo system supports automatic adaptation to pole taper and diameter changes. Replaceable molds fit 60-400mm round and octagonal light poles without manual adjustment.

Basically no need. Pulse MIG mixed gas welding ensures ultra-low spatter and smooth weld surface. Ultra-short head-tail residue avoids manual repair welding, with no deformation or surface indentation.

Very easy. Intelligent CNC automatic control supports one-person operation with no professional technique required. Non-hydraulic design eliminates oil leakage faults and reduces maintenance work. Remote diagnosis function simplifies after-sales service.
