It comes with a thermal overload protection system. If you push the duty cycle too hard (welding for too long without a break), the machine will shut down the output and trigger a warning light, protecting the internal components from burning out. While the duty cycle is limited by its 120A max output, it is honestly rated (unlike many imported competitors that claim "200A" but deliver 140A).
(often labeled as the "Due MIG 120") is a classic, Italian-engineered transformer-based welding machine built by . Celebrated for its rugged dependability in light fabrication, automotive sheet metal repair, and home DIY projects, this dual-purpose welder operates on standard single-phase mains power. It can handle both gas-shielded solid wire (MIG/MAG) and gasless flux-cored wire . cem dual mig 120 manual
The manual states 15% at maximum output (120A). That means weld for 1.5 minutes, then rest for 8.5 minutes. If you weld below 90A, you can achieve a 30% duty cycle. It comes with a thermal overload protection system
