Features:
  1. VRD Adjustable (Voltage Reduction Device)
    The VRD safety feature reduces no-load voltage to a safer level, preventing electric shock hazards, especially in high-risk environments like damp or confined spaces. An adjustable VRD allows users to toggle this function based on workplace safety requirements, ensuring compliance with international standards while maintaining operational flexibility.

  2. Arc Force Adjustable
    Arc force control stabilizes the welding arc, preventing electrode sticking-particularly when using low-hydrogen or basic electrodes. By adjusting the arc force, welders can optimize performance for different materials and thicknesses, ensuring smooth arcs in various conditions, including overhead or vertical welding.

  3. Hot Start Adjustable
    A hot start function delivers an initial surge of current to ignite the arc effortlessly, even with difficult-to-start electrodes. Adjustable hot start lets welders fine-tune this burst based on electrode type or material thickness, reducing frustration and improving weld pool initiation.

  4. Recommended for 5.0mm Electrode
    This machine is engineered to handle 5.0mm electrodes efficiently, making it ideal for heavy-duty applications like structural steel welding, shipbuilding, or pipeline construction. Its robust output ensures consistent penetration and deposition rates for thicker materials.

  5. Suitable for Acid, Basic, and Cellulosic Electrodes
    Compatibility with multiple electrode types (acidic for mild steel, basic for low-hydrogen requirements, and cellulosic for high-speed vertical-down welding) makes this machine highly adaptable. Each electrode type demands specific current characteristics, and this unit's precision settings cater to all three without compromising arc quality.

  6. Tri-Proof Air Duct Design
    The tri-proof (dust-proof, moisture-proof, and corrosion-proof) air duct system enhances the machine's longevity by protecting internal components from harsh environments. This design ensures optimal cooling efficiency even in dusty workshops, humid sites, or corrosive industrial settings, reducing downtime due to overheating or part degradation.
