advanced inverter technology, use quality imported power devices with high frequency, small size, light weight using pulse width control technology by overheating, over current, over voltage, under voltage protection device contacts using contact or non-cutting, strong arc performance

High-frequency transformers using ferrite materials, loss, conversion rate, high efficiency

simple structure, process quality, durable and reliable, easy to maintain cutting current stable, smooth and slotted lose up with power lack of phase, undervoltage, overvoltage devices, welding safety more practical.
