MMA-I SERIES MMA Welder

Welding machine manufacturerSince 1988
MMA-I SERIES MMA Welder，Manual Metal Arc Welding Features Super micro-crystal magnetic material is applied in the main transformer for enhanced performance. Using single tube IGBT, the welder features better quality at a more affordable price than mold IGBT. Air passage is designed to protect against water, dust and wind erosion, increasing the stability of the inner workings of the machine. The fan heat diffusion efficiency can reach up to 100%, greatly increasing the duty cycle of the welder. When working in 40 degree environments, the duty cycle is no less than 55% The output efficiency can be up to 93%, the max, power factor can be up to 0.95. Stable welding current even when the input voltage is fluctuating. Hot arc starting as well as VRD function.
