Gouging machine
ND-500 Inverter Multi-functional Welding Machine
The ND-500 welding machine is a high-performance, industrial power source. It is very reliable. This one system does MMA, TIG, MIG, and Carbon Arc Gouging. So, it is a complete solution for heavy work like shipbuilding and petrol-chemical jobs. It uses advanced special technology. This means it gives precise results even in tough places. It has a 100% duty cycle and can start an arc at only 5A. Because of this, the ND-500 welding machine has a very stable arc, little spatter, and enough power for big steel structures.
ZX7-800 IGBT Inverter Gouging Machine
The IGBT Gouging/MMA Welder is a cutting-edge, dual-purpose industrial tool engineered to deliver unmatched performance in carbon arc gouging and manual metal arc (MMA) welding applications. Built with advanced IGBT inverter technology, this machine ensures superior arc stability, energy efficiency (up to 30% reduced power consumption), and precise control across demanding tasks like metal removal, joint preparation, and heavy-duty welding.
Designed for durability, its rugged construction withstands harsh environments, while features like hot-start, anti-stick, and overload protection enhance operational safety. The welder supports electrodes up to 6.0mm for MMA welding and gouging carbons up to 8mm, making it ideal for industries like shipbuilding, construction, pipeline fabrication, and machinery repair. With a wide input voltage range, it adapts seamlessly to global power grids, and its compact, portable design ensures ease of transport to job sites.
Engineered for professionals, this welder combines industrial-grade power with user-friendly controls, including adjustable current settings and a digital display for real-time monitoring. Whether removing defects in steel beams or welding thick plates, the IGBT Gouging/MMA Welder guarantees productivity, precision, and long-term reliability.
