12m Pulse MIG CNC Pole Shut Welding | 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 integrated straight seam welding for long light poles.
No welding deformation, no burn-through, ultra-low spatter and no manual repair welding required, ideal automated equipment for mass production of municipal street light poles.
Core Advantages
Premium Welding Finish: Pulse MIG welding with Ar85~90% + CO₂10~15% mixed shielding gas. Minimal spatter, smooth weld seam, no post polishing needed. Welded poles maintain perfect round shape without deformation, burn-through, indentation or flattening.
Full CNC Self-Adaptive Adjustment: Full servo system with 3 sets of precision presser feet and V-slot worktable. Automatically adjust clamping pressure, foot position and welding speed to match pole taper and diameter differences, zero manual tuning during production.
Hydraulic-Free Design for Low Maintenance: Remove traditional hydraulic unit to eliminate oil leakage completely. Lower breakdown rate and daily maintenance cost for stable long-term running.
Ultra-Short Unwelded Edge: Optimized welding travel achieves full-length welding from pole top to bottom. Barely short leftover unwelded section, no extra repair welding work.
Easy Operation & Less Labor Burden: Built-in weld monitoring camera for real-time seam viewing and tracking. Fast trolley return and simple pole loading support single-person operation with low skill requirement.
Wide Production Compatibility: Swapable molds fit 60-400mm round tapered poles and octagonal poles. Standard unit works for 2.5-6mm plates; optional heavy-duty model supports up to 8mm thick material.
Stable Continuous Production: Custom smooth-moving worktable and rear guide plate reduce frequent welding gun adjustment. Constant 1~3m/min welding speed fits standardized mass production lines.
Frequently Asked Questions
Q1: What mixed gas is matched with the pulse welding system?
It adopts mixed gas of 85~90% Argon + 10~15% CO₂, which can greatly reduce welding spatter.
Q2: What optional upgrades can expand the machine's production capacity?
You can choose automatic loading & unloading system or remote network diagnosis function to improve production efficiency.
Q3: Is it available to weld thick wall heavy light poles?
Yes, select the CNCSM400 heavy-duty version, which supports maximum 8mm thick steel plate welding.
