- Starting arc capability: The arc can start directly at a distance of 1-2 cm without needing to pull. - Temperature and applications: The arc reaches about 1200 degrees Celsius, producing an orange-yellow flame. This enables copper wire melting and supports a wide range of metalworking and experimental uses. - Drive technology and performance: This driver board uses an H-bridge with a 4-tube MOS frequency-conversion resonance topology, delivering high drive efficiency and strong overall performance. - Thermal characteristics: Low heat generation means no radiator is required for operation. - Practical use scenarios: - In a workshop or lab, quickly ignite the arc without pulling equipment, streamlining setup for demonstrations or experiments. - For metalworking tasks such as melting copper wire, taking advantage of the 1200 C arc temperature in small-scale projects or prototyping. - As a development platform for evaluating resonant H-bridge MOSFET drive topology, benefiting from high efficiency and reduced thermal management needs.
