Safety features are well-covered with protections against over-current, over-voltage, and over-heating.

A standout feature is the synergic control, which automatically adjusts settings based on the welding wire and gas material, making it user-friendly, even for beginners. For professionals, the manual MIG mode allows for custom settings. The welder comes with a comprehensive set of accessories, so you can start welding right out of the box.
