DSW1600 Engine Driven Arc Welder with DC IGBT System
Industrial-Grade Submerged Arc Welding Solution
The DSW-1600 is a premium DC IGBT submerged arc welder engineered for heavy-duty industrial applications, delivering exceptional performance, stability, and energy efficiency. Powered by advanced IGBT module full-bridge soft-switching inverter technology, this welder ensures maximum energy savings while maintaining consistent output quality — making it the top choice for steel structure fabrication, shipbuilding, pressure vessel manufacturing, and large-scale pipeline projects.
With a wide welding current range of 200-1600A and compatibility with welding wire diameters from 3mm to 6mm, the DSW-1600 accommodates diverse welding needs, from thin-gauge precision work to thick-plate deep penetration. Its 100% rated duty cycle guarantees uninterrupted operation even during prolonged high-current welding tasks, while the 84±4V output no-load voltage ensures reliable arc ignition and stable weld pool control.
Key Features & Benefits
Advanced IGBT Inverter Technology - Full-bridge soft-switching inverter design ensures 93% high full-load efficiency and significant energy savings compared to traditional welders. The IGBT module delivers stable current output and fast response, ideal for high-speed welding applications.
Ultra-High Power & Wide Operating Range - Welding current range: 200-1600A (supports 3-6mm welding wire) with 84±4V output no-load voltage for reliable arc starting. 100% rated duty cycle enables continuous high-current operation without overheating.
Superior Weld Quality & Control - Integrated arc force adjustment function optimizes weld bead formation, minimizes spatter, and allows precise control over penetration depth — resulting in smooth, clean welds with minimal post-weld finishing required.
Robust Grid Adaptability - Exceptional immunity to power grid fluctuations (tolerates ±15% voltage variation), ensuring stable performance in industrial environments with unstable power supplies.
Heavy-Duty Industrial Build - Weighing 156kg with compact external dimensions (850*420*1440mm), the machine balances durability and portability. Its 83KVA rated input power and 153A input current deliver consistent power for the most demanding welding tasks.
