Why choose the power and precision of the STAHLWERK ARC 200 MD Digital?
This welding machine stands out for its versatility and integrated technologies that make work easier, even for less experienced users. It features a digital display for clear reading of all parameters, as well as an intuitive menu for quick adjustments.
Among its key features are Hotstart for optimal arc ignition, Anti-Stick to prevent electrode sticking, and ARC-Force to stabilize the electric arc. For enhanced safety, the VRD (Voltage Reduction Device) function can be manually activated to reduce the open-circuit voltage. In addition, this model includes a reference current function that suggests the ideal amperage depending on the material thickness (1.0–10.0 mm) and electrode diameter (1.6–5.0 mm). Its compact structure, weighing only 3.4 kg, makes it perfectly portable.
