Features & Benefits
-
Advanced Technology: Uses soft switch technology. This provides high efficiency and reduces power consumption.
-
Stable Performance: Delivers a very stable electric arc. This creates a quiet molten pool and produces fine, high-quality welds.
-
Comprehensive Protection: Built-in systems protect against overcurrent, overheating, and over/under voltage. This ensures operational safety and machine durability.
-
User-Friendly Controls: Features a digital display for real-time monitoring of current and voltage. Allows for easy current presetting.
-
Adjustable Arc Control: Separate controls for arc-ignition current and thrust current. This optimizes arc starting and prevents the electrode from sticking.
-
Wide Compatibility: Works with all standard MMA electrodes up to 5.0mm. Suitable for almost all welding applications.
-
Robust Power Supply: Designed for 3-phase 380V input. Tolerates voltage fluctuations up to ±20%, ideal for unstable power grids.
-
Portable Design: Compact dimensions and light weight (35kg). Integrated handle allows for easy movement between job sites.
-
Optional Accessory: A remote control box can be supplied. This adds convenience for the operator.
