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.
