Mma Welding Machine

Product Detail

Product description:

1, the adoption of advanced inverter technology can ensure the welding current in the grid voltage fluctuations and arc length changes in a high degree of stability, arc self-regulation ability, arc soft

2, with overheating protection function: when the machine overload operation, appear internal parts overheating and other abnormal circumstances, the main circuit of the machine stops working, protect itself, and the abnormal indicator light "bright"

3, welding spatter is small

4, it is easy to start the arc

5, welding deposition rate is high

6, welding deformation is small, weld formation is good

7, light weight, small size, easy to move

8, high efficiency, high power factor, is a highly efficient energy-saving equipment

Mma Welding Machine Maintenance Methods

The power indicator light is normal, the fan rotation is normal, no welding output

 

1) check all kinds of connecting and inserting wires in the machine for bad contact;

 

2) there is a disconnection or bad contact at the output terminal;

 

3) overheat protection lamp is bright;

 

A. indicates overheating due to protection. In this case, you do not have to unplug the power plug to cool down the fan for sustainable work. Cool the welder and re weld it when the indicator goes out;

 

B. check if the heat switch is damaged and replace if it is damaged
