Metal Body
DC Constant Voltage — mild steel, stainless steel, and aluminium with minimal spatter.
Dual output mode — uniform penetration and consistent weld quality during continuous MIG welding operations.
Seamless switching between MIG/MAG and ARC/MMA — one machine for multiple applications.
Constant current / constant voltage output ensures uniform penetration and clean weld bead finish.
Uses up to 50% less electricity than older transformer-based systems — reduces operational costs.
Intuitive digital display and controls make setup and parameter adjustment fast and easy.
Operates from 330–500VAC — compatible with DG set / generator power on Indian construction sites.
Auto thermal cutout and overload protection ensures long equipment life in continuous operation.
The 365–500V wide input voltage range makes it particularly well-suited for construction sites in India where DG set or generator power is the primary supply — a common challenge for heavy infrastructure projects.
