KEYGREE Welding Machine Model ARC-500Z/ARC-630/ARC-1000/ARC-1250

The ARC series (ARC-500Z/ARC-630/ARC-1000/ARC-1250) represents a new generation of high-performance welding systems designed for professional and industrial applications. Utilizing advanced full-bridge inverter soft switch control technology with dual IGBT modules and quick recovery diode modules, these machines deliver exceptional arc stability and energy efficiency while minimizing power loss. The built-in protection system safeguards against undervoltage, overvoltage, and overcurrent conditions, ensuring reliable operation in demanding environments.  With versatile functionality including Gouging, MMA, and LIFT TIG welding modes, the ARC series adapts to various welding requirements across different industries. The adjustable arc-force and hot start features allow for precise control over welding performance, while the anti-stick function prevents electrode sticking for uninterrupted operation. The inclusion of VRD (ON/OFF option) and wired remote control capability enhances both safety and convenience.  Engineered for extended reach, these welders support welding cables up to 100 meters without compromising performance. Multiple insulation materials protect critical components such as PCBs and main circuits, ensuring durability even in harsh working conditions. Combining robust construction with intelligent features, the ARC series offers professionals a powerful, adaptable, and dependable welding solution for challenging applications.

OVERLOAD PRODUCTION

Automatically cuts power when current or temperature exceeds safe limits to protect the welder and components.Prevents damage from overheating or overcurrent.Extends machine lifespan.Fault codes display on LCD for quick troubleshooting.

3-IN-1 VERSATILITY

Due to its functionality, the device allows you to carry out the following types of work:Gouging / MMA / LIFT TIG.

VRD FUNCTION

The VRD (Open Circuit Voltage Reduction) feature improves safety and eliminates the risk of electric shock to the welder. The welding process becomes safer in confined spaces and when welding in high humidity conditions.

ARC FORCE

ARC FORCE dynamically adjusts welding current to stabilize the MMA arc, preventing sticking and improving penetration. It automatically boosts current during arc length changes for consistent performance, especially in vertical/overhead welding.

REMOTE CONNECTOR

During arc welding, when both hands are occupied, allows the welder to control the welding current during operation. This creates the conditions for obtaining the highest quality of the weld and increases productivity.
