1 Imported mosfet, IGBT power component, 2 Small in size, mini, portable, 3 inverter MMA arc welding machine - details see: https://www.machineto.com/small-portable-mma-arc-inverter-welding-machine-welder-10134407

Small MMA Mosfet IGBT Inverter DC Arc Welding Machine

MOSFET SERIES:

Adopting advanced PWM inverter technology, ensuring precise control

Built-in automatic protection from over voltage, over current and over heat, safe, reliable and durable

VRD electric shock proof function is addible, humanistic design. no load voltage is between 9v and 15v

Built-in hot striking arc starting function, easy to start arc

ZX7-250S runs on both 220v/380v, voltage can be converted automatically.

IGBT SERIES:

Adopting PWM technology, stable quality and reasonable structure

Driven by Monotube IGBT, safe, reliable and durable

Main transformer uses nanometer and non-transistor material, with high duty cycle, which makes welding machine of 3 phases is able to work continually in high temperature of 40c
