220V Multi-Function Stick Welder Mma-300Sic Digital Signal Control Inverter Arc Welding Machine Silicon Carbide

1. Input power: 3-phase 380V, 50/60Hz.

2. Inverter arc welder built around advanced Silicon Carbide (SiC) power core. It delivers stable current output, high energy efficiency and strong anti-interference capability, enabling reliable welding even under unstable and complex power supply conditions.

3. Compared with conventional IGBT solutions, SiC technology achieves higher energy efficiency, lower heat generation and faster dynamic response. It creates a stable arc with reduced spatter, supports higher duty cycle and offers better tolerance against input voltage fluctuation. It allows the machine to be compact and lightweight with extended service life, perfectly suited for heavy-duty MMA welding.

4. Supports dual welding processes: MMA and Lift TIG. Two welding modes satisfy various welding requirements. It can handle conventional manual electrode welding (MMA) as well as precision Lift TIG welding for thin materials, making it a multi-purpose welder for multiple applications.

5. Compatible with a wide range of welding electrodes including E6013, E7018, E6010 and more. Works great with carbon steel, low alloy steel and other commonly used industrial metals.

6. Equipped with practical functions and full safety protections: Hot Start, Arc Force, Anti-Stick and VRD plus overheat protection. Hot Start guarantees easy and reliable arc ignition. Arc Force increases weld penetration for clean weld beads. Anti-Stick function prevents electrode sticking to the workpiece to boost working efficiency. VRD reduces open-circuit voltage automatically below 30V for electric shock prevention, critical for humid or confined work areas. Overheat protection protects the machine and extends service life to ensure safe and stable welding.

7. It features fast dynamic response and outstanding welding performance with low spatter and smooth, uniform weld beads of high mechanical strength and durability. Fast response instantly adapts to varying welding speeds. Less spatter cuts down post-weld cleaning work, while consistent weld appearance delivers reliable welding quality for long-term operation.

8. User-friendly operation, suitable for both professional welders and hobbyists.

9. The machine comes with a complete set of accessories including:

• -electrode holder, 2.0m
• - earth clamp 2.0 m
• - Face mask
• - Brush

Specifications:
