POWER I-200 RECHARGEABLE BATTERY WELDER: FEATURE OVERVIEW

In this video, we take a close look at the COROTC MMA-200BL cordless stick welder and demonstrate how its dual power modes work in practice. You'll see the 20–80A output range, the 20–50A hot start function, and how the internal 36V battery pack compares with an external 40–84V battery input for extended operation. We also walk through the 72V no-load voltage, IP23 protection, and 2–10mm welding thickness so you can judge whether this 6.7kg portable welder fits your site work. Watch to understand the two operating modes and what they mean for repairs and installations away from mains power.
