The PT-500 Plasma Tube Welding Machine is an industrial-grade solution for clean, precise, and reliable welding of metal tubes and pipes. Using advanced plasma arc technology, it produces a concentrated, high-temperature arc for deep penetration and stable single-sided welding with double-sided formation, making it ideal for stainless steel, aluminum alloy, carbon steel, and copper. With a 100% duty cycle enabled by external water cooling, the machine supports continuous operation in demanding production environments. Its dual-mode function allows seamless switching between plasma and TIG welding, providing exceptional flexibility for various materials and thicknesses (0.2–12 mm).
Main Features
Dual-mode Operation: Supports both plasma and TIG welding.
Minimal Heat-Affected Zone: Keyhole effect allows for stable single-sided welding with double-sided results and minimal heat impact.
High Duty Cycle: 100% duty cycle with external water cooling ensures stability and reliability, extending equipment lifespan.
Flexible Power Source: P and T sources can be used separately or together for welding various thicknesses.
Easy to Use and Maintain: Simple operation and easy maintenance reduce worker training time.
