Description

• Using updated inverter switch technology which has inverting frequency from *0Hz or *0Hz up to *0KHz, processes advantages of lower switching consumable, high efficiency of the power conversion, low input power.
• The high-power IGBT module as primary switching device, fast recovery diode as rectifier, solid-state circuit design.
• Adopt advanced waveform control technology and output curve to improve droplet transfer, Stability of the process, welding quality, appearance of bead and reducing spatter.
• Optimized arc-start sequence and feedback testing technology makes the possibility rapid arc starting, up-slope stable process, and wiping off small curve loop when ending arc.
• *-step/*-step/self-locking selector: By 4 step program, reducing labor intensity and improving the quality of weld joints is available in a wide range or long welding joint.
• Multiple protected functions: over heat, over current, short circuit, through corresponding abnormal indicator.
