MIG-250K/350K MIG Welder

The MIG-250K/350K MIG welder is a piece of welding equipment designed for civil and industrial uses. Featuring a great protection system, the machine can operate safely, reliably and has a long service life. It has automatic undervoltage, overcurrent, overheat and phase lack protection functions. Under protected conditions, the machine will automatically stop wire and gas feeding. In addition, the anti short circuit design of the control wire effectively prevents the welder from damage when wire over cover gets ripped or torn. Moreover, the machine has good anti interference ability, which uses CBB anti explosion capacitor as filter capacitor, ensuring high power factor.

More Product Information
Precise Control System
1. Due to the PWM controller, closed loop control system, the machine works stably under strong power fluctuations. It can still perform normal welding operation when the minimum input voltage is 330 V.
2. The MIG-250K/350K MIG welder is multifunctional, which also has MMA welding function.
3. The separated welder and wire feeder design makes it easy to adjust wire feeding parameters.
Advanced Inverter Technology
1. The adoption of full bridge inverter power conversion technology with 20 kHz high frequency significantly reduces the size and weight of the power supply.
2. The waveform control technology with inductor regulating function makes it possible to adjust inductance in accordance with the welding process requirements. This helps to achieve softer arc, greater depth of penetration and fewer spatters.
3. Slow wire feeding and small ball peeling at the arc ending state contribute to increasing success rate of next arc starting.
4. The spot welding function makes the MIG welding machine ideal for thin plate welding applications.

As a professional MIG-250K/350K MIG welder manufacturer and supplier in China, we also offer KIND TIG welder, MIG/MMA-250Y MIG welder, CUT50C/70C/100C plasma cutter, and much more.
