Technical Features & Performance Advantages
-
Wide-Voltage Resilience: Specially engineered to handle input voltage fluctuations between 260V and 440V. This ensures consistent welding penetration even when operating on unstable construction site power grids or long-distance cable extensions.
-
100% Heavy-Duty Duty Cycle: Designed for continuous, high-intensity workloads. The internal cooling system and F-class insulation allow the machine to maintain peak performance during 24/7 industrial operations without overheating.
-
Precision Digital Control: Features intuitive stepless adjustment for both welding current and time. The digital interface provides high-accuracy settings, ensuring repeatable, defect-free welding results for every single stud.
-
Three-in-One Versatility: Beyond specialized stud welding, this power source supports Manual Arc (SMAW) welding and Carbon Air Gouging, providing a cost-effective, multi-purpose tool for metal fabrication and maintenance.
-
Advanced Safety Interlocks: Built-in intelligent sensors monitor for over-current, under-voltage, and thermal overload. The system automatically triggers a protective shutdown to prevent equipment damage and ensure operator safety.
Steel Structures
Professional stud welding solutions for industrial plants and steel frameworks, ensuring high-strength structural integrity.
Bridge Construction
Reliable welding for shear studs and anchor bolts in bridge engineering, designed for 100% duty cycle in outdoor projects.
High-rise Buildings
Efficiently weld shear connectors for steel floor decks and embedded parts, optimized for high-intensity construction.
Shipbuilding
Perfect for welding insulation pins and outfitting components in shipyards, featuring a compact design for flexible operation.
High Efficiency, Low Labor Cost
Rapid Learning: A regular welder can master basic operations in just 30 minutes and achieve professional proficiency within 1 hour.
Superior Productivity: Delivers a welding speed of 10-20 pieces/minute (depending on stud diameter), significantly accelerating your project timeline.
Broad Material & Process Compatibility
Multi-Material Support: Perfectly suited for low-carbon steel, stainless steel, galvanized sheet, alloy steel, and even copper or aluminum.
All-Position Welding: Supports flat, vertical, overhead, and oblique welding, adaptable to complex structural requirements.
Surface Flexibility: Capable of welding on smooth surfaces without the need for extensive pre-treatment (oxide layers, oil, or primer removal).
