1. Precision display of present current.
2. Discrete IGBT inverter technology in characterized by steadiness, less splashing, low electricity consumption, high working frequency, high efficiency, low noise and high performance of interference protection.
3. Perfect self-protection function in cases of over-voltage, low-voltage, over-current, over heat, safe and reliable.
4. Thrust current can be adjusted continuously with intensive are thrust force and prevent to be stuck.
5. Applicable to acid and alkaline welding rod, can be used to weld in any position and for carbon are air gouging.
