General View of Control Panel


Many machines claim they're powerful, but we make it real. Real maximum output is 400A@60% duty cycle. Real open circuit voltage is 70-80V. Everpro MMA-400i provides you more than enough.


Reliability is always the first thing for a welder. We use the latest inverter technology and stable IGBT module to ensure it. Based on the strong reliability, you can weld your imaginations.

Cellulose electrodes

Thanks of it's powerful and reliability, MMA-400i is not only good at welding regular electrode, but also special electrodes. It is specially designed for cellulose electrodes and it's 100% safe for vertical-down welds and with a professional welding performance.


function reliably ignites the electrode and melts perfectly to ensure the best quality even at the start of the seam.This solution makes lack of fusion and cold welds a thing of the past and significantly reduces weld reinforcement. Adjust the hot start current here and the time here.

Arcforce correction (welding characteristics)

Perfect for large construction sites and very tough assembly work with mains supply leads up to 50 metres or connected directly to a generator. High tolerance to mains fluctuations ensures a perfect welding result.
