MMA welding machine is a handheld welding equipment, also known as manual arc welding machine. It adopts IGBT inverter technology, melts and joins metal materials together by electric arc. Metal transfer waveform control provides stable electric arc, easy arc starting, little splashing, stable current and well-shaped welding lines.MMA electric welding machine is suitable for welding various metal materials, such as steel, copper, aluminum and so on. Applicable to welding wire of different specifications of 1.0-5.0mm. It can be widely used in acid and basic electrode welding. It has the advantages of easy operation, high portability and low price, and is widely used in construction, manufacturing, automotive repairing and other fields. Features: Premium Material: Compact design makes the overall shape more attractive. The front and back panel are made of high-intensity engineering plastics, with high insulation, which effectively ensures reliable performance of the machines in severe conditions. Light weight and portable, economize energy and high efficient. Digital Display: With large digital display, the display of welding current provides a visual and convenient operation, you can see the data clearly. IGBT Technology: Adopts IGBT inverter technology, the high inverter frequency greatly reduces the size and weight of the welder. And greatly reduce the magnetic and resistance loss obviously enhances the welding efficiency and energy saving effect. MMA Manual Wleding: Efficiency, energy saving, portable, stable arc, high no-load voltage, and with high compensation of arc force, are able to meet various welding requirements in field work. Multifunctional Design: Switching frequency is beyond audiorange, which almost eliminates noise pollution. Metal transfer waveform control provides stable electric arc, easy arc starting, little splashing, stable current and well-shaped welding lines. LED Indicator Lights: Equipped with two indicator light, the power light indicates that the power switch of the machine is on, and the overheating light on indicates that the temperature inside the machine is to high and the machine is under overheating protections status. Cooling Fan andamp Exhaust Holes: With a built-in high-efficiency cooling fan, with fine heat dispersing capability, long hours of work can be ensured, extending the machineand 39 s service lifespan. The design of multiple exhaust holes can effectively dissipate heat and avoids the harm caused by overheating of the machine. Multiple Protections Functions: With over-temperature, over-current, and over-voltage protections, it is safer to use. Perfect protective circuit and fault display function provides safety, reliability, and convenience to locate a fault. Wide Applications: Applicable to welding wire of different specifications of 1.0-5.0mm. With high efficiency, high stability and high reliability for all kinds of welding work. It can be widely used in acid and basic electrode welding.
