Key Features:

 

Advanced IGBT Inverter Technology

Offers stable performance and up to 85% energy efficiency, reducing power loss and operating costs.

 

Heavy-Duty Operation

With a 100% duty cycle at normal temperatures, the machine is capable of continuous welding for 24 hours. Even in high-heat environments (up to 40°C), it maintains a 60% duty cycle at full current.

 

Precise PWM Control System

Equipped with a closed-loop Pulse Width Modulation (PWM) system for exact arc control, ensuring smooth, high-quality welds.

 

Wide Current Range (20–300A)

Suitable for light to heavy-duty jobs with a stepless adjustable current, allowing maximum control for a variety of applications.

 

Supports 1.6mm to 5.0mm Electrodes

Works efficiently with a wide range of electrode sizes for versatility across welding tasks.

 

Multi-Layer Protection

Integrated system protections prevent damage from overload, overheating, and electrode sticking for safe and extended operation.

 

Lightweight & Portable

Compact, easy to carry, and ideal for fieldwork or remote site welding.
