Arc630t Inverter DC Arc Welding Machine

IGBT Module for Stable and High-Power Performance
The welding machine utilizes an advanced IGBT (Insulated Gate Bipolar Transistor) module, ensuring stable performance and high power output. This technology enhances energy efficiency, reduces heat generation, and provides precise control over welding current, resulting in smoother arcs and better weld quality. The IGBT module also improves durability, making the machine suitable for heavy-duty industrial applications.

Three-Proof Air Duct Design for Enhanced Reliability
The welding machine features a three-proof (waterproof, dustproof, and wind erosion-proof) air duct design, significantly improving the reliability and load endurance of internal electronic components. This design prevents moisture, dust, and harsh environmental factors from damaging critical parts, ensuring stable operation in challenging conditions such as construction sites, shipyards, and outdoor welding tasks.

No-Load Voltage of 75V with Wide Welding Compatibility
With a no-load voltage of 75V, this welding machine can efficiently weld both acidic and alkaline welding rods, offering versatility for various welding applications. Additionally, it supports long cable extensions of up to 100 to 150 meters (with a conductor cross-sectional area ≥50mm²), providing flexibility in large-scale welding projects without significant power loss.

Adjustable Thermal Arc Current for Consistent Welding Performance
The machine includes an adjustable thermal arc current function, addressing the issue of inconsistent thermal arc currents when using different types of welding rods. This feature allows welders to fine-tune the arc characteristics based on the electrode type, material thickness, and welding position, ensuring optimal performance and minimizing spatter or sticking.

Ideal for Butt Welding of Steel Bars Below ∅25mm
This welding machine is particularly suitable for butt welding of steel bars with diameters below ∅25mm, making it an excellent choice for construction, reinforcement welding, and metal fabrication. Its high power output and stable arc ensure strong, clean welds even on thick steel bars, improving productivity in structural welding applications.
