Dc Standing Spot Welding Machine Multipoint 3mm Point Resistance Galvanized Tube Multi Head
Dc China Made Standing SpotWelding Machine Multipoint 3Mm Point Resistance Galvanized Tube Multi Head Point Spot Welding Machine
This DC multi-point resistance spot welding machine is engineered for high-quality joining of galvanized tubes. At its core is an integrated intelligent welding system, precisely tailored to overcome the challenges of galvanizing. Its dual welding heads are synchronized by an independently adjustable smart controller, achieving millisecond-level precision. The system auto-compensates for variations caused by uneven galvanized layers or workpiece tolerances, eliminating defects like weak welds, burn-through, and spatter. Coupled with an efficient water-cooling system and high-hardness electrodes, it guarantees stable, long-duration operation. Simple to use, it produces two consistent, perfect weld spots per cycle, delivering both efficiency and quality for multi-point welding of galvanized tubes.

-
Expert in Galvanizing: Process-optimized for galvanized layers. Intelligent waveform control effectively breaks through the zinc layer to form strong, clean weld nuggets.
-
Robid & Stable Construction: Heavy-duty steel frame offers high rigidity and stability, resisting welding impact to ensure precise spot location and high repeatability accuracy.
-
Efficient Man-Machine Collaboration: Combines manual loading/unloading with fully automatic welding cycles, significantly reducing labor intensity and ensuring consistent quality.
-
Durable & Serviceable Design: Features a high-flow internal water-cooling system and high-wear-resistant chromium zirconium copper electrodes. Rust-proof waterway components with independent drainage allow for easy monitoring and maintenance, supporting continuous high-volume production
Dual-Head Synchronization, Doubled Efficiency: Two precisely calibrated welding gun heads complete two high-quality weld spots simultaneously in a single cycle, increasing production efficiency by nearly 100% compared to traditional single-head spot welding machines.
All waterway components undergo surface treatment to prevent rusting, and waterway drainage is independently discharged to the water tank. Based on the outflow situation, blockages in the waterway can be observed and eliminated.
Pressure & Auxiliary Systems
- Cushioned Pressure Control: The descent/ascent speed of the pressure head is adjustable, cushioning impact on the workpiece and reducing noise.
-
Stable Welding Force: A dedicated air storage tank helps buffer pressure fluctuations, ensuring consistent and stable welding force output for more uniform weld quality.
