Performance characteristics

✱ MCU control system, reacts immediately to all changes

✱ Adopt IGBT high-frequency inverter technology.

✱ High-definition digital display screen, simple and convenient operation.

✱ High reliability: After long-term practical testing, the technology is mature and stable. It can maintain good working performance in various harsh environments and is not prone to malfunctions.

✱Easy to operate: The technical requirements for operators are relatively low. With a certain amount of training, they can start operating. It is suitable for welders of different levels.

✱ High weld strength: Under correct operation, welds with high strength and good sealing performance can be obtained, meeting the quality requirements of most projects.

✱ Built-in arc control lets you get in tight without sticking the electrode.

✱ Hot Start Function reliably ignites the electrode and melts perfectly to ensure the best quality even at the start of the seam.

✱ Arc Force makes it easier to weld large-drop melting electrode types at low current strengths with a short arc in particular.

✱ 110V/220V dual voltage design.

✱ Light in weight and suitable for scene welding both indoors and outdoors.
