2.energy saving .

3.Hot start ,arc force

Detailed Product Description
  Mma Welding Machine (General)
Model No.: MMA-315(IGBT)

  Details: 1.Equipped with imported IGBT of high power to output high welding current. 2.The Tri-proof(water, dust and eroding proof) cooling system raised the reliability and duty cycle of the key components. 3.The duty cycle is higher than 50% when the temperature of the operation surrounding is around 400C.Capable to operate outdoors. 4.The maximum output efficiency is 85%. By using the advanced electro-circuit for power factor compensation, 5.With the functions of Arc-Force, adjustable Hot-Star current. With digital display of the welding current and remote control for option.
