• Single-Wire & Twin-Wire/Tandem Capability – Supports advanced SAW welding strategies (including single and twin wire tandem configurations) to improve productivity and deposition rates.

• Power Supply: 3-phase AC (typically 380–480 V ±10%)

• Rated Input Capacity: ~55 kVA

• Output Current Range: ~60–1000 A

• Duty Cycle: 100 % @ 1000 A (continuous heavy-duty operation)

• Output Voltage Range: ~22–44 V

• Wire Size (SAW): 3.0–6.0 mm

• Protection Class: IP21S (protection against dust and water spray)

• Insulation Class: H (high thermal endurance)

• Dimensions: ~788 × 366 × 815 mm

• Weight: ~95 kg

• MCU + CPLD Control System: Precise electronic control for stable welding performance and flexible parameter adjustments.

• 100 % Duty Cycle: Suited for continuous industrial welding operations without overheating.

• Embedded Parameters: Built-in expert database with preset welding parameters simplifies setup.

• Reduced Voltage Sensitivity: Less affected by fluctuations in input power, maintaining stable output.
