DNT Series Table Type Resistance Spot Welding Machine 50~200KVA

DNT Series Table Type Resistance Spot Welding Machine 

The DNT Series Table Type Resistance Spot Welding Machine represents a revolutionary advancement in manual resistance welding technology, specifically designed for flexible, precision welding of diverse workpiece shapes and sizes. With a power range spanning 50KVA to 200KVA, this innovative desktop spot welder features a unique flat-bed design that replaces the conventional lower electrode with a stable, adjustable welding table. This allows operators to place workpieces directly on the table surface and manually position them under the welding gun for spot-by-spot welding. Ideal for prototyping, small batch production, repair work, and complex component assembly, the DNT Series combines operator-friendly flexibility with professional-grade welding performance.

Product Overview:

The DNT Series Table Type Spot Welder operates on the resistance welding principle but introduces a groundbreaking table-based design. Unlike traditional spot welders with paired moving electrodes, the DNT Series features a stationary, height-adjustable flat welding table (acting as the lower electrode) and a multi-joint articulated welding gun (the upper electrode). Operators simply place the workpiece on the table, manually maneuver it to the desired welding position, and activate the weld cycle. This innovative approach eliminates workpiece handling constraints, reduces fixturing requirements, and enables welding at virtually any point within the table's working area. The system is particularly valuable for irregularly shaped components, mixed-material assemblies, and applications where traditional fixturing is impractical.

Machine Structure & Key Components:

• Heavy-Duty Welded Steel Frame with Integrated Welding Table – Provides exceptional stability with a flat, robust welding surface that serves as the universal lower electrode.
• Adjustable Height Welding Table – Features a 200mm vertical stroke (750-950mm total height range), allowing quick adaptation to different workpiece thicknesses and operator ergonomics.
• Multi-Joint Articulated Welding Gun – A flexible, balanced welding gun with multiple articulation points, enabling easy manual positioning to reach any spot on the workpiece without moving the component.
• High-Capacity Welding Transformer – 380-440V AC input, 50/60Hz compatible, rated for continuous industrial operation across the 50-200KVA power range.
• WELTOUCH CT-110C Intelligent LCD Controller – Advanced microprocessor-based control system with full-color LCD display, offering precise programming of welding schedules, current, time, and monitoring functions. Features error diagnostics, step programming, and real-time parameter display.
• Programmable Pneumatic Pressure System – Delivers consistent electrode force through the welding gun, with adjustable pressure settings for different material types and thicknesses.
• Modular Table Surface – Standard 1000mm x 800mm welding table (custom sizes available) with replaceable surface plates to accommodate different welding applications.
• Ergonomic Operator Interface – All controls and displays are positioned for comfortable operation, with clear visual feedback and intuitive programming.
• Integrated Safety Systems – Includes safety interlocks, emergency stop, and protective guarding to ensure operator safety during manual positioning and welding operations.
