Spot Welding Machine Series

Our Spot Welding Machine series offers a complete range of reliable welding solutions — from compact bench-top models to high-capacity industrial units. This series includes DN-20KVA, DN-35KVA, DTN-63KVA, DTN-100KVA, DTN-150KVA, and DTN-200KVA Spot Welding Machine models.

DN-20KVA DN-35KVA DTN-63KVA DTN-100KVA DTN-150KVA DTN-200KVA

These machines are designed using proven mains-frequency resistance spot welding technology, delivering stable welding performance and consistent weld quality across a wide range of applications. Spot welding uses a controlled electric current to join metal sheet workpieces by heat generated through resistance at the contact points.

The machines can be equipped with different electrode types, foot pedals, and pneumatic controls to fit specific production workflows.

Key Features

Wide Capacity Range Spanning 20KVA to 200KVA, the range covers everything from light-duty metal parts to higher-strength industrial components without a gap in between.
Stable Power Frequency Welding Technology Built on mature mains-frequency resistance spot welding technology, it keeps current output reliable and weld formation consistent, run after run.
Strong Machine Structure A rigid body design keeps vibration and deformation in check during welding, which is exactly what long-term stable operation depends on.
Flexible Electrode Configuration Electrode tips, arms, and fixtures can all be swapped in depending on workpiece material, size, and welding position.
Optional Pneumatic Control Pneumatic models bring controlled electrode pressure into the mix, lifting welding stability across repeated production cycles.
Easy Operation and Adjustment Welding time, pressure, and current settings adjust to fit material thickness and whatever the welding job calls for.
Suitable for Multiple Metal Materials Commonly put to work on carbon steel, stainless steel, galvanized sheet, iron parts, and other conductive metal components.
Factory Manufacturing Support Backed by an experienced welding automation equipment manufacturer, with R&D capability, quality control, and technical service all built into the offering.

Application Areas

The Power Frequency Spot Welding Machine series finds its way into metal product manufacturing, hardware processing, sheet metal fabrication, automotive component production, household appliance parts, kitchenware manufacturing, wire product welding, frame welding, cabinet parts, metal brackets, stainless steel products, and general industrial metal joining processes across the board.

  • Metal product manufacturing
