Keygree TIG-400PACDC-W Analysis of core technology features
Full-Function Welding Mode Integration
The TIG-400PACDC-W utilizes advanced inverter technology to truly achieve full process coverage:
AC/DC TIG Welding: Provides professional solutions for aluminum-magnesium alloys (Ac Tig) and stainless steel/carbon steel (DC TIG)
AC/DC MMA Manual Arc Welding: Adapts to diverse needs for different materials and welding positions
Multi-Waveform Output: Selectable sine wave, triangle wave, and square wave waveforms to meet the special requirements of different metal materials for arc characteristics
- Precision Current Control Technology
DC Initial Current as low as 10A: Enables fine welding of ultra-thin materials (above 0.3mm)
AC Initial Current 20A: Provides stable arc ignition capability for thin aluminum alloy plates
Fine Pulse Frequency Adjustment: Wide range adjustment of DC pulse 0.2-500Hz, AC pulse 0.2-200Hz, and AC frequency 20-250Hz
- Intelligent Operating System
Process Parameter Storage/Recall Function: Saves frequently used welding processes for one-click recall, significantly improving efficiency in repetitive tasks.
Diverse Operation Modes: Four modes: 2T/4T/4T2/spot welding, adaptable to welding tasks ranging from simple to complex.
Comprehensive Remote Control:
6-pin foot pedal/TIG welding torch current adjustment
50-meter MMA wired remote control, suitable for large workpiece operations.
- Innovative Cooling and Safety System
Water-cooled/Air-cooled Dual Mode: Integrated water tank design supports long-term high-load operation.
Multiple Insulation Protections: PCB and main circuit utilize multi-layer insulation materials to ensure long-term stable operation.
Pressure Protection Mechanism: Water/air pressure monitoring and automatic protection to prevent cooling system malfunction
Application scenarioss
- Aerospace and Precision Manufacturing: The TIG-400PACDC-W's high-frequency pulse capability (up to 500Hz) and micro-current control characteristics make it ideal for thin-walled structural components and engine parts in aerospace applications. The square wave output mode is particularly suitable for precision welding of difficult-to-weld materials such as titanium alloys and high-temperature alloys.
- Aluminum Alloy Structures and Pressure Vessels: A wide range of AC frequency adjustment from 20-250Hz, combined with AC square wave output, effectively breaks down the oxide film on aluminum alloy surfaces, achieving high-quality welding. A water-cooling system ensures stability during long-term continuous welding of large workpieces such as aluminum storage tanks and ship structures.
- Artistic Metal Creation and Restoration: This equipment offers unprecedented control precision for metal sculpture, decorative art creation, and artifact restoration. Storeable welding parameters allow artists to accurately reproduce specific texture effects, while multiple waveform options provide technical possibilities for creative expression.
- Piping Engineering and On-Site Construction: The trolley-style integrated design combined with 50-meter remote control functionality makes the TIG-400PACDC-W ideal for outdoor operations such as pipeline installation and power plant construction. The MMA remote control function allows welders to remotely adjust parameters when working in complex positions.
- Diverse Production EnvironmentsFrom welding plates of varying thicknesses in automobile manufacturing, to the fabrication of stainless steel containers in food machinery, and busbar connections in the power industry, this equipment's full-process coverage reduces enterprise equipment investment and achieves a highly efficient "one machine, multiple uses" production model..
