ARC-220H/ARC-280H/ARC-350H/ARC-300Q/ARC-400Q ARC WELDER 1/2/3PH 160-450V MULTI BOARDS

The ​ARC-220H/ARC-280H/ARC-350H/ARC-300Q/ARC-400Q​ series represents a line of advanced ​DC inverter welding machines​ designed for professional ​MMA and Lift TIG welding​ applications. These units feature ​automatic voltage identification (160-450V)​​ with comprehensive ​undervoltage, overvoltage, and overcurrent protection, ensuring stable operation across various power conditions. Equipped with ​adjustable arc-force control, ​hot start, and ​anti-stick functions, the machines deliver superior arc performance and easier operation. With ​generator compatibility (2-layer and multi-board types)​​ and optional ​VRD (Voltage Reduction Device)​, this series offers versatile solutions for both workshop and field welding applications, combining robust performance with operational safety.

	OVERLOAD PRODUCTIION
	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.
	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.
	2-IN-1 VERSATILITY
	In addition to the main MMA mode, the model also has an additional LIFT TIG welding mode.
	INFORMATIVE DASHBOARD
	A digital display on the control panel shows the value of the current and additional cutting parameters. With the help of knobs, you can set the values of the main current and additional parameters. Switch buttons and a clear cyclogram allow you to adjust all stages of the welding process.
