EACO WSM-400D Digital Inverter Pulse TIG Welder
The EACO WSM-400D Digital Inverter Pulse TIG Welder is an industrial-grade 350A GTAW machine designed for high-specification process piping, power generation equipment, and automated fabrication lines. Featuring 99 programmable memory channels, it ensures 100% parameter repeatability across work shifts.
With comprehensive pulse parameter control (peak current, base current, frequency, and duty ratio), the WSM-400D achieves deep root penetration with minimal heat distortion. It incorporates cold welding for ultra-low heat input and integrates seamlessly with mechanized welding carriages and robotic positioners.
